Forward Fuel Lines??

The rubber part on my 90 coupes forward fuel lines is looking very bad. I dont want to risk one giving out. Does anyone have a part number for the forward parts for the send and return? Has anyone repaired these? I picked up a used pair from an 89 cheap on Ebay and was thinking of cuttting them and replacing the rubber part with braided. I have never done anything with braided lines either though. Anyone have any ideas, pointers or help with this situation?

Thanks,
Doug

you are talking the rubber lines that lead up to the block, then hook up with metal lines to the rail?

If so, there is nothing special about them, just fuel injection rubber hose. Can get it by the foot at your local autozone. Just need the right size.

Mine are only rubber for about a foot. They are molded into the solid metal lines with some sort of crimped joint. I can't replace just the rubber part from what I can see. The local NAPA does hydraulic line repair but wont do these as they are fuel lines.
I saw it awhile ago, but cant find it in a search of the Archives. Anyone?

Thanks,
Doug

ps, does anyone know if the 89 lines are a direct replacement for the 90?

yes you can. On the 87, the rubber lines are held on by clamps.

Unless this changed...

call Chris May at Superior Chevy, 1.800.728.8267.

Forward Fuel Line Repair Questions???

I called Chris and the lines for the 90 were discontinued in 01..

I had notes on this but they got lost somewhere between computers and hard drive crashes.....

I cant find the info through the search of the archives either. I guess I am going to have to resort to pulling them and cutting, flanging, and putting a small piece of braided in there. Any pointers or tips on braided/AN fittings welcome as I have never worked with it before. Also I am figuring on AN-6 (should this work for both send and receive?), any idea as to the max radius bend for a fuel line? Are all the hose/fittings the same or is there a difference in quality between the manufacturers? Don't wanna cheap out as it looks to be a ..... to pull the lines. Do I need to drain the fuel tank prior to this? The Helms doesnt mention it, but i dont want to end up with $50 of gas in the driveway either. How can I test the fuel lines for leaks before I put them back on?

Thanks,
Doug

For a fuel application I would go with Aeroquip fittings and braided hose. You can find a local industrial supply store that fabs hydraulic hose make up the hoses for you, they should be able to pressure test them as well. Shouldn't be too hard or cost more than $50 for the fittings and hose.
