Have the 'stock' rubber fuel lines going from my frame rail (where the 3/8" hard line ends) up to the steel lines that connect to the TPI fuel rail.........and want a better alternative. These lines can leak (my original ones started dripping the day after I got back from a 200 mile camping trip), and guess where they are located - on the drivers side right about 8 inches from the headers. Anyone using any aftermarket or trick braided stainless supply and return lines? When I had these made they only had high pressure rubber available at the oil filter supply house.

Sounds like the lines arent long enough to me. I have the stock lines from the rails, connected to a set of factory hoses that I cut off one end of and hooked that up to the lines that were on the car. Only thing I did to the lines on the car was bubble the ends so the hose wouldnt pull off, and just clamped it in place. Its been like that for 7 years and 12k miles and hasnt leaked one bit.
I have seen some people here say they found that stupid saginaw flare fitting the factory uses, so you could hook that up to the rail, run some hard line to the frame, bubble the ends and clamp a piece of high pressure fuel line inbetween that and the line on the car.
If you want fancy, there are flare fittings and stuff available for flexible line, and then you just have to flare the hard lines which isnt difficult with some experience and the right tools. You can spend big bucks and get aeroquip or earls fittings, or something along those lines (others make stuff, like Russell and probably others I am forgetting) and use all their stuff to hook it up.

 

Actually the lines are plenty long, and are the stock length IROC ones.........what I am after is a more robust hose - maybe a stainless steel braided line that will NOT leak ever (if that is even possible). The dealer said he couldn't even get the stock lines for a month!

Thanks.

Stainless steel lines wear out too. so there is no such thing as never leaking unless you go to something like plain hardlines. Stainless is probably more abrasion resistent and may last somewhat longer than normal rubber hoses. I believe that you should be able to order the ends you need to fab up a supply and return line to replace your factory one.

You might want to look at using AN braided steel lines. On the two conversion's i've used these fittings Accel makes that adapt the saginaw fittings to AN-something (6 maybe.) I then took the AN out to hose barbs, but you coudl just run steel line from there down to some more adapters and then to the stock fuel line.

 

I've got a mini-ram in my 89 IROC. On this intake the fuel line hook-ups are in the back. I bought the stainless braid and AN fittings from Summit. TPIS sent some trick fittings to connect the hard line to the hoses(they may be the Accel fittings mentioned above). It looks real nice and cost under a hundred dollars.
