Fuel line size

[DHartley]

Can someone tell me at what hp you need what size fuel line? I am putting a 97 215 hp motor in a 84 chev,currently the truck has a turbopropane smallblock so i am going to have to put fuel tanks and lines back on the truck and i thought now would be the time to upgrade. i have the stock lines which are 3/8. i hope to see350 to 400hp,800to1000 tq , as the truck is a daily driver and tow vehicle. thx Dana

3/8" supply and 5/16" return are the stock sizes. Plenty of fuel flow for the HP you are looking at and more.
