stock replacements I'm not sure...you can buy fuel line by the foot at some auto parts houses or you can order it from summit or jegs....use to be able to atleast...prolly still can....then bend it yourself...not sure how you make the stock connections though...may have to make flare fittings and splice the stock type ends on....
ok well under the car where they run along the frame rail right before where it starts to go up into the engine compartment one of my lines looks smashed not sure if its stock and supposed to be that way but during tunning i had no problems with fuel tunning? Its been like that since i have had the car. Can anyone verify if thats how one of their lines are? Again this is under the car at the bottom very front before it starts to go up, thanks
i will need to take a pic it seems thits the return line to me since the pressure one is a little fatter? there are a total of 4 lines running next to each other any one know which ones are the fuel and are the other 2 brake
any suggestions???? are your guys like this or am i screwed funny it seams smashed shut but if it is the return line wouldnt too much pressure build up
Thats actually more of a jobber kit I think than what he would want....if it were me I would go to the local parts house, buy a piece of steel line whatever size that is(maybe cut a piece out to get it right) then buy a bender and a flaring tool....and all the right brass connections which they should have....then with the piece cut out, bend you a replacement and put it inline....simple to do even if it sounds difficult.....total cost with tools under 20 bucks....if you know someone who has tools maybe 2 bucks....
do make sure where you cut out have enough straight line to make the flares and put the fittings on...takes a coupel inches usually....

is it for sure a fuel or is it a brake line? Im pretty sure its the return since its smaller than the one next to it. I guess its still flowing back to the tank since i havent had any problems im not sure how it got smashed because none of the other lines are like that and the bigger diameter one hangs a tad lower? Its been like this since i had the car
* on a side thought can i do a -8 and -6 hoses and do away with the steel lines? but how would they hook to the factory fuel rail manifold and pickup in the tank?

sounds like i will probably do that i have a bender/cutter/double flare tool
I just put -8 and -6 lines in my 97... I bought it as a roller and it had no fuel lines. I got the fuel rail adapters from Summit. The hardest part I had was finding the fitting to go on the fuel hat. I also did away with the stock fuel filter and used a summit filter with -8 fittings.

cool what are the part numbers for the adapters? im having trouble looking fot the ones for the hat as well
I'm not sure on which line it is whether brake/return/pressure line....probably could be traced back easily....If you have the money I would go with custom lines.....that would support you into your future mods and shouldn't be too difficult to do.
guys do you think im ok to just leave it? I mean its been like that since i had it 4+ years I dont have any problems so im sure if its the return line that its still allowing the fuel to go back to the tank right? If the line was completely blocked what would happen to much pressure in the rails or what
If you are not going lean at WOT, and your fuel pressure is correct at the top of a WOT run, then your supply line is good enough.
If you are not going rich when you are pumping the maximum amount of fuel, and your fuel pressure is not going too high, then your return line is good enough.
You might want to not go offroading in your Cobra any more though...

yeah its weird im not sure how it got like that if i hit something alle the others should of been like that too i wonder if its something factory? My car has been tuned and no fuel issues on the dyno
what should wot fuel psi be? im on stock rails and regulator 42 lb injectors also i have a kb BAP
Fuel PSI should always be 39 PSI above what is in your manifold. If you are NA, then the vacuum will be 0 at WOT so your fuel pressure should be 39 PSI at WOT. If you are running 6 PSI at WOT with a blower, your fuel pressure should be 6+39=45 PSI.
At idle with stock cams, your vacuum will be 18-22" of Mercury which is about -10 PSI. so at idle you should be seeing 39-10=29 PSI of fuel pressure.

i think im going to just repair the section with some steel line and use compression fittings. Any one know the o/d of the stock lines? 5/16 or 3/8 the return is probably 5/16 but im not positive, the fuel line repair kits, or rolls come in 5/16 or 3/8. Thanks

That is E.A's old car, isn't it? The crazy House of Boost car with the built motor and F1 ProCharger and auto tranny?
-edit- Read further into your thread. It is. Very cool!
