at 171k miles, i needed a new fuel pump on my 91 RS 305 TBI. I went the easy way out and cut an access panel for the fuel pump, and had to cut the fuel lines to do so. the fuel line and clamps i got from lowes looked pretty weak, does anyone have any suggestions for the permenant fix?

I am open to any ideas so that i don't have to worry about this ever again

I have seen the AN adapters they sell on Jegs, do they work pretty well, if so what sizes do i need?

 

No one?? Really?!?!

 

Use brass compression fittings. Especially on the high pressure line. If you must use hose, use fuel injection hose not regular cheap gas line.

 

Okay, so i used the brass compression fittings, secured everything down, and go hit the key, the pump primes, and i hear a hissing noise which was gas spewing from the fittings. Didn't work very well, I'm running out of ideas here

 

TBI should not be to high as fuel pressures go. (vortech are up to 60 psi !) A pic may help. Also plumbing for water is done with compression fittings-so it should work. I can tell you that AN adapters to hard line are available in some sizes but they do work like the compression fittings though. Maybe you are not getting the comp ring in the right spot-they should go where the angled edge so that as they get tighter they "compress" on the outside of the tube. I use them on 80 psi paint lines at work and they do work. HTH

AN fittings also use an inverted flare union and all the adapters and ect can ad up$ fast.

 

Not to sound like a total ******* here, but this is exactly why those of us who have lots of car knowledge always belittle poeple doing this exact same thing. Then dozens of hacks come in and enourage it, now you get to deal with the problems. You forever have butchered fuel lines on the car. YOur best bet at this point would be to get some decent quality hose clamps and use some good quality fuel line and double clamp it. Dont look for a lot of help.

 

Thanks for nothing!

Please don't reply if you do not have useful information

 

Tighten them down more. I'm assuming the line was clean and you used the right size fittings. They will work if used right.

 

If this is what you want to do, go for it. i did and have no regrets.

There's a picture of my so called "hack job" on my second reply to this post https://www.thirdgen.org/forums/tech...-question.html
I used fuel injection hose on all, but the supply line. The 3/8" coupling you see is a carbon steel Swagelok tube to tube fitting. You can find a distributor here http://www.swagelok.com/distributors...nited%20States

 

Thanks guys, for the info,

jv, I tried tightening them down more, but i think i stripped out the brass fittings so this complicates things a little. I'm going to try rgarcia's way and go with carbon steel fittings. The website you sent me for swagelock gives the closest dealer to me about an hour away, going to try to go there this weekend and pick up all the fittings.

I'll keep you posted on my progress.

PS rgarcia, your "hack job" looks pretty clean, good job, did you polish your gastank while you were in there? its shiny

 

Got an update,
Went to parts store and picked up 2ft of fuel injection rated fuel line, double clamped everything with fuel hose clamps (not pressure clamps from hardware store) and everything is secure, no leaks, car runs great.

 

I guess my useless information was good for something huh?

BTW, those are called hose clamps and rubber line. Labeling it as fuel injection is to make people feel good about using it. It doesnt matter what psi the hose is rated for, its the hose clamps at the end that dictate its potential.
