Fuel Line Size

[AirForceOne]

Anyone know what size carburetor fuel line hose my 1985 Bayliner Capri 85hp Force Motor takes?

3/8's, 5/8's? It's pretty old, so no markings on it. Also any local stores to get marine grade fuel line hose instead of ordering off line?

Thanks

Profile? Could be 1/4In or5/16.I've seen them with both.Any auto store should have both.Auto Zone and Advance in my area carry both.Napa etc.
If U are gonna change,change ALL the hoses.Squeezie too.Then install a water seperating filter in the line.J

Carb nipples take a 5/16 hose. You can force on a 1/4 hose and 3/8 will need to be clamped tightly. Personally, I use 3/8 from tank to carbs.

Gas pumps don't know if the gas is going into a boat or a car. Any fuel line is fine.

I just replaced 7? of 1970s-fuel line and 1985?s in-line filter on a 35 HP Chrysler on a 15? Raycraft and it was not fun or my preference. You have to be creative but Safe!!

1. I could only find a marine grade in Napa?s catalog as a 3/8?, 7' kit vs 5/16?/ 3/8? hose needed due to in-line filter/fitting/applications in a non kit form.

2. I had to adapt/modify/with the ?gray marine grade hose kit? vs the 10? of 5 /16? or 3/8? plastic hose. Orig line looked like plastic vs new gray reinforced line.

Good Lick!

Not if you wish to remain compliant with Coast Guard regs it isn't. You have to use USCG-approved fuel line. Good luck collecting on your insurance if you have a fuel fire and the fuel line isn't approved, even if the line wasn't directly responsible for the fire.
