Old rusty fuel line..

[H.G.P.]

Old rusty fuel line in beater car. Some drops after driving. Can I DIY replace without messing things up?

1. 1994 (going on 18years) GM LaSabre fuel line=18 years old. Appears to be steel.

2. Can I "splice" out the worst place ?

3. Can I "splice" out without spilling gas all over the place?

4. What type of fuel line do I use?

5. How do I connect to old line to a splice (if possible)?

6. Anything else to look out for?


(Note: This project would be easy with my old 911E)

I replaced the fuel lines in my old truck. I used steel brake line from the local FLAPS. I got a tubing bender, and a tubing cutter. You might be able to get some fittings that would allow you to cut out the bad part and replace. But I think it would be better to just replace the entire line. You can buy brake line in different diameters, at about 5' long. Easy enough. good luck.

PS . Drain the gas tank first! Drive till it's low, then drain into a gas can when you take the first connection apart!

A friend of mine fixed part of a rusty steel line on his car, which has CIS, so the pressure is probably lower. He just got high pressure fuel line, and used hose clamps to secure the splice. It has held together for a few years so far...

It,s routine to repair rusty fuel lines with sections of fuel injection rated hose. The Lesabre is probably rusted out under the firewall /front seat area.
There is a special hose clamp available which doesn,t cut into the hose like an ordinary gear type clamp does. No need to drain the tank The fuel pump won,t be running and only a small amount of fuel will leak out when the line is cut. .Use a small tube cutter ,not a hack saw blade.

There is a slight drip that stops after driving around the fuel filter, which is located at the outside bottom beneath the passenger rear.

Rusty lines under there. So along your idea, since the pump won't be running, I'll check with Advanced or NAPA and see if they have FI hose. It's dry under there right now with the car sitting.

I'll also have to see how far I can get the car up safely to work under there.

Thanks for all the information everyone.
