I finally got in contact with Walbro. The 400-952 is supposed to have two copper washers in the kit. I'll get a washer out to those that ordered kits in the past few days. Sorry 'bout that. It wasn't my fault. We'll get it sorted out soon. Ron Gregory Auto Performance Engineering http://apeusa.com/

I noticed that my latest batch of 400-952 kits had only one copper washer. I didn't think much about it until I saw your note. I contacted Walbro engineering, but the "engineer in charge of copper washers" is on vacation. I'm pretty sure that kit needs two copper washers, so I'm ordering some of those washers today. I hope to get them the middle of next week. FYI, I'm out of install kits again. The warehouse said that Walbro has to make more. I'll make sure this next batch has the proper number of washers. Sorry 'bout that.

I guess the confusion is my fault.... sorry. I updated the WWW site. It now states 400-952. Hope that helps. Ron

They are all physically the same size and shape. The only differences are the flow characteristics. Go to the "External" page of http://apeusa.com and click on the "flow graph" links under each part number. For example - at 60 psi with a 12 volt source GSL393 - ~29 gal/hr - enough for about 300 hp GSL391 - ~33 gal/hr - enough for about 350 hp GSL392 - ~52 gal/hr - enough for about 600 hp If you send 13-14 volts to the pumps, you'll get even more fuel

If you only need the 400-952 installation bag-o-bits, it's $10.50 - 15% = $8.92 plus $2.00 for shipping. That's a total of $10.92. I will take paypal funds for that, too.

The problem that most folks have is the fact that the Walbro pumps have 10mm x 1.0 threads. You probably won't find fittings at AutoZone with those threads. Most hydraulic shops don't carry metric fittings, either. I haven't been able to find 'em in the aftermarket; I have to get mine from Walbro. If you can find the fittings, you'll also need those special aluminum washers to get your outlet fitting to seal properly. I don't know of anyone that carries those.

I'm going to attempt to avoid all the paperwork nightmare that a Group Purchase generates. I'm going to offer a June Special. Now through the end of June, APE is giving StarQuest members a fifteen percent discount when you order an external fuel pump and install kit for your car. So, that means GSL393 w/ 400-952 = $120 + 10.50 = 130.50 - 15% = 110.93 GSL391 w/ 400-952 = $130 + 10.50 = 140.50 - 15% = 119.43 GSL392 w/ 400-952 = $140 + 10.50 = 150.50 - 15% = 127.93 Just add the pump and installation parts to your shopping cart, then use the promotion code STARQUEST to get your discount. I don't currently have any 400-952 kits in stock. They don't move too quickly so I don't stock more than a couple. You guys are going to change that. I just ordered 25 more. The warehouse has 7 that they are shipping tomorrow, and they'll have more from Walbro by the end of the week or early next week. If you guys order more than 25, I'll get more. If you have non credit card paypal funds you'd rather use, send 'em to my personal paypal account - ron@gregoryusa.net. Be sure to tell me what you want. I'll fill all the orders that arrive through the end of June. If I run out, I'll ship 'em as soon as I can. Prices include shipping via USPS Priority Mail. Orders that have to go outside the US will be shipped via USPS Global Express, and you'll need to pay a bit more to cover that... check http://ircalc.usps.gov/ for shipping details. A single pump is two pounds when it's all packed-up. If you have any questions, let me know. Ron Gregory Auto Performance Engineering http://apeusa.com/

Greetings, The Professor called me today, to get some information. He said that members of this forum are being told they can get a Walbro fuel pump kit for their Starion/Conquest. When then get the kit, they find that the kit is not a bolt-in replacement. Please don't blame Walbro. blame your vendor. The Professor asked me to do my best to clear things up. I am NOT here to sell you something. I am only here to provide you information. A few years ago Walbro saw the need for an external fuel pump line that would replace Bosch and Denso pumps. They created the GSL39x pumps. They are all the same size and have 10mm x 1.0 threads at each end. Walbro then created some kits that would be OE replacements for certain vehicles. Those kits contain the GSL39x pump that is closest to OE specs and a plastic bag with any other parts an owner would need to do the swap. Those kits have part numbers GCL6xx. For example, the Starion/Conquest OE replacement kit is GCL616. That kit contains the GSL393 pump and the installation bag-o-bits 400-952. http://apeusa.com/pics/gcl616.jpg The installation bag-o-bits contains a 12mm inlet fitting [128-3025] along with a 12mm threaded fitting [128-3075] that is sorta like a banjo fitting [but different]. The kit also contains the wiring terminals and nuts, and a foam sleeve. Plus, there are a couple unique aluminum washers that are only used in the 400-952 kit. They are used with your OE fittings to connect the outlet. Since most of you are looking for performance upgrade pumps, you can't just order the GCL616 kit. If you call a vendor that doesn't deal with these pumps all the time, and ask for a kit that contains the high pressure 255 pump [GSL392], you'll probably end up with the wrong installation bag-o-bit. You really need to get the 400-952. Summary ----------- Get the 400-952 installation bag-o-bits and then whatever external pump you'll need to support your power level. You can find flow graphs for all the GSL39x pumps on the "External" page of http://apeusa.com Thanks, Ron Gregory Auto Performance Engineering
