280i rubber fuel lines

Are the rubber fuel lines, not the hard plastic one, that run behind the sill panel standard low pressure lines?, pretty sure they are return lines. Want to replace them as I have the sill panel off for outrigger work.

Thanks.

Yes, I think. Mine has hard plastic for supply line, and softer 'ordinary' carb type fuel line for return.

(Original Ford setup used hard plastic for both)

Pretty sure it was not high pressure fuel line when i replaced Delilah's from tank to pump to metering head..I think its only the plastic lines that are high pressure...

Yep, I replaced my nylon supply line with HP rubber fuel hose, but the return line is not HP as it just runs back to the tank.

If they are the same size as the low pressure ones between the tanks and the pump, they are 5/8" which is a common marine size. Grady
