Running fuel line from tank to engine

[Dwight]

I bought 3/8" steel line at the local part store in different lengths.
Make you bends with the least amount of degrees. A straight line would be perfect but you will have some bends. Use 45's not 90's, 30's instead of 45's. Long sweeping bends not sharp ones. Make sure the rubber hose you install is ethanol rated.

Make sure your fuel fitler has a 3/8" inlet and out.

Last fall I install a 5/16" inlet on a 3/8" fuel line. Took the Cobra with a 525 Hp motor for a test drive. It would starve out in the upper rpm range. Stopped at a part store and ask if he had a large filter with a 3/8" in and out. Back to the shop install new filter and problem gone.

Moral of the story: everything in the fuel line system can be a restriction.

if you have a motor that puts out 250 hp then the fuel line is not a critical as a 500 horse motor.

And three fuel filter will starve a motor out in the upper rpm range. Fuel filters are restrictive. Some more than others.

Lessons learned the hard way
there are automotive calculator to help determine fuel line size using the hp of the motor. 3/8" line will support 500 hp.
