Technology Posted October 7, 2012 Report Share Posted October 7, 2012 (edited) This could be moved to E&P Mods section. More people will see it here though. SO! I grew tired of the constant groan from the A1000. It impresses people at first, but I can get better performance from two stock-replacement wally 255s. I bought one from a friend, and the other from an SQC member! You can get them for under 100 dollars. Here I am drilling out the inlet fittings to 1/4" so they can flow more, ya heard?http://i.imgur.com/Vpo1d.jpg And here is the finished inlet side with new copper crush washers, and as you can see, I had to order a new foam sleeve for the left pump. It came with two rubber coated straps. I will probably use one for each pump.http://i.imgur.com/i3AZo.jpg I ordered 110 bucks worth of fittings and hose to keep the high pressure side all AN aluminum stuff. it will go -6AN from the pumps into a Y fitting with a -8AN outlet into a big fuel filter canister, then -8AN hardline up to the engine bay (that hardline is already in place). That junk should be here in a couple days, then I can assemble. Edited October 17, 2012 by Technology Link to comment Share on other sites More sharing options...
Komeuppance Posted October 7, 2012 Report Share Posted October 7, 2012 Thread title win. Wal-BRO 255's aren't stock replacement, they're an upgrade aren't they?? You could not use the foam surrounds to keep the impressive fuel pump whine/vibes... lol... -Robert Link to comment Share on other sites More sharing options...
psu_Crash Posted October 8, 2012 Report Share Posted October 8, 2012 Looks like some good stuff Tech! Was the whine/vibration the only reason you are changing things out? Or were you reaching the limits of the A100? BTW on my latest Wally install I didn't use the foam insulation ... seemed trivial at the time. Now ... well I guess it's just singing to me Link to comment Share on other sites More sharing options...
Technology Posted October 8, 2012 Author Report Share Posted October 8, 2012 lol, I liked the title as well. I meant stock replacement as in size and fit. As for my reasons, I was no where near the limit of the A1000, it's good for 650 awhp on a DD, so maybe 730 or so on a rear drive car. These two wallys will support more than that (supposedly this type of setup has made more than 800). I am going to run a wire from the ECU and switch on the second pump at something like 5 psi of boost so that it's not always running. It's a nice aside that having two pumps will make it a great backup incase of primary pump failure. all you'd need to do is stay out of boost, or keep it at wastegate pressure until you got a replacement walBRO.

You have a good high quality check valve? Otherwise all your fuel follows the path of least resistance back to the tank via the non-running pump. I have used double pumper setups in an EVO VIII and EVO X and loved it in both due to the lower noise over a massive single pump, and you don't over run a stock FPR at idle with a double pumper like you can with a large single pump... I saved more money by keeping the stock FPR than I spent on getting the double pumper setup. Keith Link to comment Share on other sites More sharing options...

Technology Posted October 10, 2012 Author Report Share Posted October 10, 2012 AN fittings have arrived sans the Y fitting, which shipped from Georgia and should be here tomorrow. I'm going to buy a couple "standard" wrenches that fit the fittings so I don't mess anything up. http://i.imgur.com/OThVl.jpg Link to comment Share on other sites More sharing options...
Skullzaflare Posted October 11, 2012 Report Share Posted October 11, 2012 im interested to see how you set it up, hurry up and get everything lol Link to comment Share on other sites More sharing options...
Technology Posted October 13, 2012 Author Report Share Posted October 13, 2012 I got the other thingy, I'm going to work on it today. I need to mount the filter, re-do the hard line to intercept the filter outlet, get a new in-tank filter from mitsu and install it all. Should go fairly easy.

Technology Posted October 14, 2012 Author Report Share Posted October 14, 2012 Went to my friend's house today and worked on the setup a bit more: Cleaned up the pump bracket.http://www.imgur.com/JZiU9.jpeg Then made a brace for two pumps. http://www.imgur.com/Fz4fZ.jpeg I got the -6 lines made as well. Pics of those later. Link to comment Share on other sites More sharing options...

Technology Posted October 17, 2012 Author Report Share Posted October 17, 2012 Ok, I haven't done a ton of work, but I did some important "by-the-way" stuff today. Earlier I put together the pumps and the -6 feed lines into the Y fitting for a little test fit.http://i.imgur.com/VLSXv.jpg I got the suction side mocked up, I just bought some brass fittings and made up a simple T. Hope it works out. http://i.imgur.com/WM2Hu.jpg But today I just did the new poly diff mounts, don't worry about that dirty diff! I am going to change the fluid pretty soon, and give it a once over with a rag.http://i.imgur.com/oy6L7.jpg Link to comment Share on other sites More sharing options...
Komeuppance Posted October 17, 2012 Report Share Posted October 17, 2012 I'd leave that grease and oil on that diff cover... slow that rust down LOL. Pumps look good though. -Robert Link to comment Share on other sites More sharing options...

Technology Posted October 17, 2012 Author Report Share Posted October 17, 2012 I'm more excited about the mounts than the pumps actually. But it'll be so nice to have quiet pumps now. BTW, the tank holds way more fuel in the far reaches than I thought. Good thing e85 doesn't stink as bad as gas, plus it evaporates quickly and doesn't leave stains on the driveway.

Technology Posted October 18, 2012 Author Report Share Posted October 18, 2012 Now I'm excited about the pumps, because they are cool looking and pretty much ready to bolt in. I got the hard part done and that was mounting the fuel filter and connecting the hardline to it. All that's left after mounting it in place and getting lines and wires in place is running a signal wire from the ecu to the trunk and installing a second relay for the secondary pump. Enough talking.http://i.imgur.com/UIs6g.jpg http://i.imgur.com/qWGi5.jpg http://i.imgur.com/6hdYu.jpg http://i.imgur.com/tH4z4.jpg And my favorite:http://i.imgur.com/T5vQn.jpg Link to comment Share on other sites More sharing options...
Komeuppance Posted October 19, 2012 Report Share Posted October 19, 2012 Plexiglass fuel pump cover, with LED's to glow them up. It'll be sweeeeeeeeet. That filter looks like it'll act as mini surge tank. It also looks like you've ran all new fuel pump wiring, correct?? -Robert Link to comment Share on other sites More sharing options...
Technology Posted October 21, 2012 Author Report Share Posted October 21, 2012 Yes, the small gauge wires are short and only go from the relays inside the trunk to the pumps. The main supply wire is a 10 gauge amp wire. I think it will be fine this way. By the way, I got the tank bolted in, I just have to connect the y fitting to the filter and test for leaks. I sure hope there aren't any. Link to comment Share on other sites More sharing options...

Technology Posted October 21, 2012 Author Report Share Posted October 21, 2012 Ok, so I made the last -8 line I needed and put it together, made sure the return line and all that was connected properly, got to hooking up the wires and tested the primary pump. It works, sucked fuel up the hose without any trouble, pressurized the system, and I found my first leak. The O-ring for the filter canister was broken. That was my fault for not greasing it up before installing. I took the o-ring out and put the can on, it didn't really leak again from there, so I decided to check the system again. I did, with next to nothing seeping from that filter, I noticed the second leak. The compression fitting after the filter was leaking. So I took off the filter can and tightened the crush fitting. Leak fixed. Testing a third time, I let it pump for a few seconds and it seemed like there wasn't anything else, but then I saw it. Coming from the -6 hose ends at the pumps. Both sides are dripping. I don't know if it's the connection to the hose, or the flared connection. I'll have to take them off the pumps and re-do them. Not hard, just a pita. So, since nothing was spraying out, I checked the fuel pressure gauge, and lo and behold, it was making pressure and holding! (slowly dropping because of those drips, but still holding). That's proof positive that these pumps have internal check valves. Don't let anyone ever tell you differently. So then I started it up, and it seemed like it started really well, very quickly. I think this setup is much better than the A1000, the car was incredibly quiet and doesn't sound like a drowning shop vac. I can't wait to fix the leaks and take it for a drive. I have to run one more wire, install one more relay and connect the power wire for the secondary pump, set the switch to come on at 5 psi of boost and let 'er buck.

Technology Posted October 30, 2012 Author Report Share Posted October 30, 2012 Whoa. Just test drove it for the first time. No leaks. That's cause I had to wait a week or so for a new o-ring for the fuel filter canister. I also soldered and heat shrinked the signal wire. It's a programmable 12v switch. I can set several parameters, so I set it to come on at 5 psi, I added a new field to the main tuning screen to show whether it was on or off, that works, and the fuel pressure gauge shows pressure is very high when in boost, so that's good. It might possibly be too much fuel for the regulator, haha, I will have to do a little more testing, but it was rush hour so I didn't get much space to get on it. If I convert it back to gasoline, I'll just disable the secondary pump. Spins 3rd gear all day every day. I didn't even think about trying a launch to test the diff mounts. But it all works, so that's great. No leaks, that's greater. 1 Link to comment Share on other sites More sharing options...

Technology Posted November 1, 2012 Author Report Share Posted November 1, 2012 indeed! Fuel pumps were just to make the car nicer to drive, and while providing more fuel than the single A1000 can do, they won't make any more power by having them instead. The whole setup is now capable of somewhere around 600, I'd say. But yes, the major bottle neck (that I can perceive) is the exhaust manifold. I also haven't ported the head or anything.
