Pushlock hose fuel line ?

[KWIKR 1]

anyone use Pushlock hose on the return and supply on the complete run from the tank to the fuel rail ??

I have used push-lok hose for may applications. HOWEVER.........Push-lok hose is NOT rated for gasoline use. At least the hose available from Parker and Jegs that I have used. It works, but it does get brittle over time. Keep an eye on it, and it will be fine. I would suggest TFE braided for a run that long.

Won't pass tech inspection at the track....but then again lots of tracks dont even check for test and tune night.
But if you compete in class racing all bets are off.

Thanks for info .

NHRA does allow push loc fuel line, just check the rule book to verify acceptable brands.

I have used it for years with no problems. Check all fuel lines frequently.

If you use push loc in the engine area, the heat may cause it to "age" quickly.:smile:

Since braided fuel lines have a history [to me anyway] of short life, we use as much metal line as possible. It is easy to put through the frame rails, and then use short braided or push loc lines at each end.

I agree with all of the above. Metallic lines are the prefered way to route fuel lines. I typically use annealed 1/2" stainless tubing, and use a mandrel bender, when feaseable. It takes a little more time, but it lasts darn near forever. They make nice steel compression fittings that are rated at 3,000 psi., so you don't need a 37* flaring tool to get an AN fitting on the end of the tube. Don't fear compression fittings. We even use them ALL-OVER comercial and Military jets, these days. (though it takes a certified operator to install them) The system pressure that I work with are 5,000 psi. Compression fittings work GREAT! Just DON'T use brass compression fittings. They are not nearly as good (or as SAFE) as the high pressure hydraulic compression fittings. Here's a good source: Steel Fittings

why doesn't anyone use the plastic fuel lines like the oems have been using for almost 20 years now? my 94 Caprice had plastic pressure and return lines from the tank to the fuel rail, and after 227,000 miles, they were still not brittle or otherwise looking worn out at all.

Some interesting discussion, on LS1tech:
Aeroquip socketless hose (FC598) - anyone else with issues? - LS1TECH
I use it, and have not had a failure. [several hotrods going on >10 yrs w/ it]. Sounds like this guy is going to take on the law dept @ Aeroquip over this deal...
Personally, I think he screwed it up when he put it together. I use a bit of "sneaky cream" on the fitting, and as the name says.. "pushlok" it together.
