Re: fuel line size
Automotive hardline for plumbing fuel and brakes, is measured on the OD. So 3/8" hardline is 3/8" on the outside. The next step up would be 1/2".

Re: fuel line size
3/8 is not big enough if it is a true 500hp engine.

Re: fuel line size

Tubing is measured on the outside, while hose is measured on the inside. Therefore, 3/8" fuel HOSE will slip over top of a 3/8" fuel TUBE, and can be secured with a worm-type gear clamp (assuming this is not a high pressure system for fuel injection of some sort). I also agree that a 1/2" line would help ensure you don't suffer fuel starvation, especially if you plan any drag racing with it. |
