How much fuel line needed for replacement?

[fastboatman29212]

1997 Seafoo Speedster twin rotax. I need to replace all fuel lines. Anyone have an idea how many feet of new line I'll need? Is the size all 3/8" ID? Thanks in advance for the feedback.

Yes... 3/8 should do it, and a bunch of stainless hose clamps. (30 or more) I would think 35' of hose would be enough.

The places that sell Seadoo parts have a parts list showing 16mm hose. Do you think that means 16mm OD or ID? Cause 3/8" ID is only 9.255mm ID.

Hose is always measured ID since it only goes over nipples and never threads into anything. The outside diameter can be different based on how much pressure it is meant to take . Pipe and tube always measured OD.

On my 2001 Sportster, some fuel hose is 6mm which is about the same as 1/4" hose and other fuel hoses are 5/16".
