When I was installing my subframe connectors...I noticed that my fuel line (the supply line) had a pinch in it. You can see scrapes right by it like I hit a stick in the road or something that bent it back a little...causing a kink in the line.

Now my fuel pressure is good, but do you think that the kink can cause a surging idle, or something else that I should be looking out for??

I am going to repair it as soon as possible...any suggestions on a new line? Should I go bigger, better...remain stock?

better to be safe than sorry...i'd fix it but a pressure gauge may tell you while driving if there is a drop in pressure that would cause a problem

go bigger

Suggestions?

I am looking on Summitt, and I am not even seeing the original ones....

I found a stainless steel line on 50Resto for $125...

i'm not sure stock is 3/8 right or that is the size to go up to?

They had 5/16 lines at 50Resto...

you dont need bigger fuel lines until you reach close to 600hp. dont even stress it. if the pressure stays good and constant through the RPM band, while under a load, you are good.

I did not think that it was all that necessary...Bigger is not always better...but you know how it goes. If you need to replace something, go with something better than stock.

Just to be sure, the wider one is the supply line right?

not sure on that one, i didn't realize they were different sizes, stock.

One is smaller than the other....I believe the smaller one is the return line, and the larger is the supply line.
