corroded rear fuel lines - replace with hose ?
My ex Canadian vette has some corrosion in the rear fuel lines.
I've got the spare tyre carrier off and removed the fuel lid. Had a good look and there's a tricky kink in the fuel lines as they go up into the dark - it will be a lot easier to replace with hose but I don't know how reliable two lengths of hose about a metre long would be.
Are there any easy ways to fit some s/s pipes and join them ?

My 87's gas line corroded through and leaked. We put a hose on it and it lasted about a year and got replaced. Now it looks like I'll have to cut some more line off, or better yet, pull the tank (UGH) and replace the lines. Whaddya expect for driving every day for 17 years?

Thanks for your replies jfb and TM. Why did the hose only last a year ? Unlucky? Poor Quality ?
I'm looking for a more permanent fix than that. Keeping my vette running is a constant battle to stay ahead of worn out or faulty parts - mine's a daily driver too, it's hard when I have to take it off the road for repair.
I'm going to check today to see what kind of fuel injection hose is available in my part of the world. It would take about 1 metre each hose.
Obviously replacing with S/S pipe is the correct solution - I can see a good place to join the new pipe to the old, under the car, but a few clues about squirrelling the pipe up to the tank would be handy.
bogus replied to my first post about this and said someone had done this a few months ago but I can't locate that post - if anyone else knows of it or can send it to me by email, please do.
Firstly, just knowing it IS possible would be very handy - it doesn't look possible without removing the tank - and that looks like a big job.
The hose longevity is a concern - so far there's one vote each way. I'd rather use s/s pipe but I'm not sure I'm prepared to remove the rear bumper and tank to do that, maybve there's a trick to getting the pre-bent pipe up to the fuel filler on top of the tank - it doesn't look easy.

If you’re talking about the “old style� rubber hose, I don’t think it works in the high-pressure fuel injection applications. The rubber type was used with carburetors where the pressure is normally only 6 – 10 PSI. In time they would bulge and burst.

I think 87SAM has the answer to my hose that lasted about a year. That hose failed in a manner I have never seen. It was split longitudinally with several splits. Maybe I need a higher pressure and gasoline rated hose.

Ok, that explains your hose problem jfb - I'm amazed, I'm sure I've got you down as an electrical 'guru' - but apparently not so hot in the fuel department!!
I did already know that fuel injection hoses are rated for much higher pressure - I believe they have to be 60-70psi although I think the vette doesn't go much above 44psi - hose is going to be so much easier to instal, it's very expensive here though.

Hot dang, I can blame that one on my vette mechanic because he selected the hose to use. I asked him if it was for gasoline and he said it was. I probably would have used the same type of hose if I had done the repair though and not considered the pressure the fuel is under from the fuel pump. I will tell him about using a better hose because even the replacement hose leaked right away.
