fuel line from gas tank help

Jvan · #1 07-18-2014, 07:15 PM

The metal fuel line from the tank to the inside fuel lines has started to leak. The factory instruction require dropping the rear sub frame as well fuel tank/exhaust as well as many other parts. I've checked w/ many mechanics and the cost is too high. I had this problem w/other SVX while on the road and local mechanic was able to lower tank enough to snake high strength rubber fuel line over tank and connect to fuel pump/inside fuel lines. Looks like I need to do this myself, so can anyone offer some advice? How is the metal line connected (w/clamps-threaded nuts), what length/diameter hose do I need (I'd like to use flexible hose covered w/stainless steel or other protected lines but these use ANA connectors). Any info to help purchase the appropriate hose/connectors is welcome.

Remove the rear seat back. ( you can actually do it just by lifting the trunk rug with seat folded, but easier to work with seat back removed ) You can get to the pump out put lines. Go get High pressure fuel line. ( a little pricey but necessary ) Connect your new rubber fuel line from the pump in and out to the old steel line where you can find a good solid place. I hope I explained this correctly. You get the idea? I had this done by my machanic on my old perlite.
Similar to this but not sure of ID of hose needed

When you connect to a solid part of the hard line, what type of clamps is required; will a worm clamps work or is something else required because of the pressure?

You should use hose injection clamp.

Have you made sure that it's the metal lines and not the rubber hoses? There are a few short pieces that join the tank hard lines to the ones that run through the body. They aren't particularly hard to replace without tearing the car apart.

I'm not sure what line is leaking. I'm recovering from a couple of surgeries and didn't want to climb into the trunk/under car but I've tried 3 local mechanics and no one wants to commit unless I tow the car to their shop and then they may decline to do the work unless I agree to the factory procedure or if the parts are rusted. I had a similar problem w/ my other SVX and it was the metal line. I won't know until I pull access panel and take a look.
