Replacing fuel lines.

Fuel Line replacement.

I have a 1995 S10 with a 262. + I live in Michigan, and the bottom of this car has been rusted to Pakistan and back.
My tank had a large rust patch on it and started leaking.
I figure while I'm in there swapping in a new tank, I might as well replace the fuel lines before they take a dump on me too. They are pretty rusty.

I called up the dealership. The only line parts they have are the pressure line and return line from the tank up to the gray filter can mounted on the frame rail. The rest on from that point has been discontinued.

PS: They want $150 for a pressure line, which I think is bullshit, because an entire new gas tank is only $100 including shipping to my door.

Suggestions?

Try a place like S10warehouse @ebay or some other junkyard.

You may also want to consider how you route your lines. If you can add a fuel heater, i think you can have some pretty decent mileage gains.

Re: Replacing fuel lines.

Anyone know if I can use a segment of rubber fuel line hose in place of the return line?

Pseudo Science. The fuel is already pretty hot just from radiant heat off the engine block. I'd imagine heating it too much could vaporize too much of it, which would just cause problems with the fuel injectors.

Besides, where do you get the energy to heat fuel to get better gas mileage? By burning more fuel. Believe it or not, but the more electricity you pull from the alternator, the more resistance on the pulley, and the harder the engine has to work. That's precisely why all of these HHO generators and the like are BS. They pull power to make power + inefficiencies at each step.

This is a new one on me. Where do/did you get your information about heating fuel inline gets better "fuel mileage"? The only thing that you'll get from hot/heated fuel inline is vapor lock.

I'm not sure as to what part of your fuel line needs to be replaced. All auto supply stores sell steel fuel lines of various lengths. All you have to do is...............MAKE YOUR OWN!

Re: Replacing fuel lines.

Hopefully you've resolved this by now, but...

I replaced fuel lines on mine. You end up buying standard straight tubing from the store and bending it yourself. The only tricky part I ran into was where it lands on the fuel pump. If the top of the fuel pump is rotted, I believe there are kits to replace that as well, but its a more specific part.

Re: Replacing fuel lines.

^ I did the tank and the pipes coming out were all rotted. Turns out the sender unit can be bought seperately for at least my 1994, $57 at advance auto. Kept my old electric pump, moved it over.

Also the lock ring was a mess. As I was trashing the old tank I just pried the outermost ring off which saved a needed inner-more ring (the "cam ring") and the o-ring. But of course the new sender came with all that again.

Re: Replacing fuel lines.

95 4.3 liter is a vortech, which is about 60 psi. i wouldnt use worm screw clamps on a pressure line like that at all. they have the rubber replacement lines in aftermarket for the high pressure, and the low pressure.

i fortunately have a tool that will flare gm fuel style.

where in michigan are you?
