Hey guys, question.

I have a 1994 XJ with 240k, slight modifications but engine is mostly stock. Here's the short question. I had to put on non-fuel injected fuel line from the lowest quick disconnect all the way to the fuel rail (it's the pressure line and not the return line). It's been working just fine the past few days and can't think of any reason why I should change it back to stock. Has anyone done this? Does anyone recommend immediately changing it back to stock?

Here's the long story. Running errands the other day, I get out at the store and fuel is pouring out the bottom of the Jeep right below the driver side door. Just past the steel fuel line and the quick disconnect the fuel line ruptured on the rubber part. So the fuel line goes from a steel line, to a disconnect, to rubber, which becomes steel again, and then to rubber again, to a disconnect that goes to the fuel rail. This all seems like a complicated way to get fuel to the fuel rail. That is a lot of areas to fail. There was an auto parts store up the street so I bought some 5/16 fuel line (regular fuel line, not fuel-injected line) and just disconnected both quick disconnects and ran the fuel line along the original line and and used some hose clamps on the steel fuel line and fuel rail. Took all of 15 mins to do that. I smelled of fuel as it ran past my glove and onto my sweatshirt, but I was able to fix it and get home. That was a few days ago and there's no leaks and everything seems to be fine. This seems to be a simple and better fix. So what do you guys think?

Thanks,

Standard regular rubber fuel line is fine for a carb and the 3 psi that mechanical fuel pumps make. EFI runs 40 to 50 PSI and uses different spec hose. It's your life to do with as you please. I know which hose I would use.

 

I'm using a rubber fuel line but I did use fuel injection fuel line and where it passes the exhaust I put a heat shield on it and it has been there for for over a year with no problems .

 

After looking at the fuel line, it says it’s for non-fuel injected use, but it also says it’s rated to 50psi. Once the weather gets better I may swap it out for actual fuel injected line and double clamp it. Heat shielding probably wouldn’t hurt either. So far there’s no leaks or anything.
