#95783, "Steel return line"


          

for those who say they ran steel fuel return lines for their SFMU, where did you get the line, what are the spec's on it?

I read posts that said it only costs around $25...but didnt notice where to get it or any specific details on running a steel line.

im trying to decide which way to go; either with the fuel line for fuel injected cars or steel line

easy on me, new to the turbo section

I will likely be posting more questions the closer I get to installing the turbo kit and getting it to run right. Thanks!

whats the difference from running a 4an and 6an? the lower fuel pressures you're able to achieve?

Precisely. Although I thought I read somewhere that guys where having issues with their fuel pressures running 4AN line? Not sure exactly though.

I ran a combination of 3/8 alum line and 6an braided.

Alum line runs under the car and braided is to run the engine bay.

where did you get the aluminum line, how much did it cost... and whats the internal diameter? did you have a special fitting on the end of the aluminum line to connect it to the 6an steel braided line and up to the pump on the other end?

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.

3/8 alum line is about 25.00 for 25' coil. Find someone to go halves with you. to terminate the line you purchase tube sleeves and tube nuts then flare the line with a double flare tool. then the line will thread onto a 6an union. internal diameter is about 5/16. OD is 3/8.

Thats not entirely true. As far as braided hose you by the correct Style fitting and you will be fine. I have never had a problem using fitting made by earls with summit brand line ect. Neither has a local speed shop.

Now you need to pay attention to the type of lien you have. Teflon line requires fitting for teflon line. Push lock hose uses push-lock fittings and you guessed it, stainless braided uses twistlock style fittings.

im running the 4500cc injectors w/ modified fuel rail & resistor pack, 255 fuel pump, SFMU w/ 2.72 discs i believe & SAFC.

This tubing comes in a coil? Do have to really worry about the line getting pinched or kinked?

I'll check out summitt and see if I can find all the right pieces...

3/8 aluminum line (25' coil)
tube sleeves
tube nuts
double flare tool to flair line
6an union
