Hello, this is my first time posting here and hoping i can get some help. Im building my sons first car 79 Malibu and doing a LS swap on it. It is a stock 5.3 truck motor and a 4l60e trans. My question is: can I run the stock fuel line (feed) from the filter to the engine? or do i need to replace that with a larger diameter? Also for a stock build, Is a 255lph pump necessary or can i run the 180lph. Any help would be greatly appreciated.

what i did on my 76skylark is run 3/8 line front to back. filter for silverado by tank. then bought new tank modified it to take silverado pump assembly. recessed a 3 side area 2 1/2 deep hole sawed a 5"hole made plate to hold seal pump with 4 bolts. on bottom of tank did 4"deep 6x6 box welded bottom of tank. pump is in that which is lowest part now so shouldnt have any starvation issues.

For my 86 monte ss swap, I used the stock 3/8" steel feed from the stock tank. I used a c5 corvette filter/regulator mounted right back by the tank so the return is short.

Thanks for the responses. I have a grand national tank I will be using and was planning on getting a pump/sending unit from racetronix along with the hotwire kit. I would like to get the 180lph pump instead of the 255lph to save some cash (being that it's a stock build). Has anyone used this pump on their build?

I'm not sure about the pump, I used a walbro 255 with my swap.

Get the 255 and be done with it once.
