check out the fittings section at jegs. They have everyting you need including al. fuel line. I wouldn't run anything but hard line under the car. You also need to only sued the same AN fittings their that companys braided fuel hose.

If you want to know what size AN fittins are this is you you do it. 1/16 icnch = 1AN so 1/4 AN = 4/16 or 1/4 and so on.

4AN line will be ok with stock injectors, however you will need 6an (3/8 .375 OD) Fuel line if you ever want to upgrade to 30# injectors. You will have problems lowering the fuel pressure past the upper 20's if you don't.
