Preludedude Posted May 14, 2015 Report Share Posted May 14, 2015 (edited) Anyone running the nylon line that is supplied with most mechanical oil pressure gauges? Ive heard stories of them breaking due to heat, etc and spilling oil in engine bay, or worse car interior... Any one using one with success? Or go braided for $60ish? or copper tubing for $15ish? I dont know and was going to use the nylon and route it wherever the best way away from all heat sources..

speedyquest Posted May 14, 2015 Report Share Posted May 14, 2015 I'm guessing most everyone is going to say avoid the nylon line for exactly what you just described. If it breaks you are going to have a problem on your hands and that line isn't difficult to break or melt. Link to comment Share on other sites More sharing options...

Power ram 50 turbo Posted May 14, 2015 Report Share Posted May 14, 2015 I've been running them for years best advice I can give you if you plane on running one is keep the line away from any heat and keep them straight and use nylon retainers to hold them in place iv never had one fail on me and have used them for about 30 years just takes good planning even copper can fail if installed wrong .

Dad Posted May 14, 2015 Report Share Posted May 14, 2015 Copper on mine Link to comment Share on other sites More sharing options...
BC_99 Posted May 14, 2015 Report Share Posted May 14, 2015 Stainless braided on mine. The extra $60 is cheap insurance that will last forever. BC_99 Link to comment Share on other sites More sharing options...
dmyers151 Posted May 14, 2015 Report Share Posted May 14, 2015 I ran the nylon for years with no issues at all, regularly saw 100+ psi on cold morning starts. I ran it inside a length of vacuum hose for most of the run inside the engine bay, to keep it from rubbing on something and failing. Link to comment Share on other sites More sharing options...
speedyquest Posted May 14, 2015 Report Share Posted May 14, 2015 That is a very good idea using vacuum line. Nice job on that idea dude. Link to comment Share on other sites More sharing options...
techboy Posted May 14, 2015 Report Share Posted May 14, 2015 I have nylon ones installed in both my Eclipse and my truck and never had a problem. Probably had it on there close to 12 years. If you run it smart (like mentioned above) you won't have issues. Link to comment Share on other sites More sharing options...

mstieg Posted June 7, 2015 Report Share Posted June 7, 2015 (edited) I've never had a problem with nylon lines, but have copper for my outside cowl-mounted oil press. gauge due to heat at source near oil filter housing/turbo. If copper line, be sure to add a few loops at mount to allow for vibration flex else any sharp angles will be taking on all vibrations at a single spot which "could" lead to softening or a break. Overbending when installing or working with can of course mess that up. I'm considering a braided line or elec. gauge for this reason and already switched to elec. fuel press. gauge. If nylon was't safe when done right, they'd not be on the market. Edited June 7, 2015 by mstieg Link to comment Share on other sites More sharing options...

I avoided using the nylon lines for fear of a cat-asstrophy in the engine bay. Link to comment Share on other sites More sharing options...
Crazy larry Posted July 31, 2015 Report Share Posted July 31, 2015 liability is the key,,, They would not sell if it could not stand up... in cased in vacuum line is a good idea. Vibration and Heat are the main reasons for failure Link to comment Share on other sites More sharing options...
