If the vehicle is carbureted, the pressure in the gas lines
is much lower. Fuel injected, runs at a much higher
pressure.

You mention a return line. Which is most likely rather low
pressure. I'd try the JB weld. as the other writer mentions.
The are needs to be clean and dry. And allow 24 hours for
curing time befor using the vehicle.

I know JB Weld will fix most anything except some plastics
and holds
well on metals. I have heard it being used on gas tanks and
never
heard of it leaking after it was used. However, someone
told me that
modern gas will eat thru it. I dont see where modern gas is
much
different than the gas was 10 years ago. I guess most of it
has some
alcohol in it, but will alcohol hurt the JB Weld?

I have a 91 Chevy truck and there is a pin hole leak in a
gas return
line in the fuel pump outlet, right before it enters the
hose. I'm
not going to spend $250 to buy a new in-tank fuel pump
(that's what I
was quoted), when the pump works fine. I would have thought
the JB
Weld would be fine, but if not, I will have a guy solder it
or braze
it (after all the gas is flushed out by pumping water thru
it). But
the JB Weld is the easiest and cheapest method to fix it.

Also, these lines have a gas hose with some really weird
fittings that
need some special tool. The guy at the parts store told me
I cant
just use regular fuel hose and clamps because fuel injection
engines
have high pressure. How high can it be? I doubt it comes
even close
to the 100psi rating of the gasline hose, and if it does,
I'll use air
compressor hose rated at 300psi. At the same time, I had a
guy who
works on cars as a hobby tell me that he has used gasline
hose for
fuel injection lines. So, who is right? I tend to think
that auto
parts store guy wanted to get his grubby hands into my
wallet with his
$250 fuel pump, $20 special tool, and $28 special hose.
$300 to fix a
damn fuel line leak is insane (not to mention the hassle of
removing
the whole gas tank).

I hate working on these newer cars. Give me something prior
to 1970
to work on, when things were still simple and parts were not
sold by
crooks.
