Mystery fuel line ID

[Nivekt]

This fuel line runs from the outlet line coming from my tank to my fuel filter. It needs to be replaced, but other than the line type itself(1/4" ID Type A) I dont know the fitting type to search for when looking for a replacement. Is it a custom job?

The fittings rotate and I need that with the new line to be able to install it properly.

I tried the OMC forum but didnt get much of a response for this most pressing need. Thanks for all the help!

Take the defective hose to your local NAPA guy and they will fabricate one for you (at least here in rural Virginia).

The fitting that rotates is the adapter from 1/4" external pipe (the hose end) to 1/4" inverted flare (hard line end). New fittings will also be available at NAPA.

Ayuh,... The ends are 1/4" Pipe thread,...

I'd put a 1/4" pipe x 3/8" hose barb in the fuel pump, 'n another 1/4" x whatever size the tank fiiting is, 'n run new approved rubber line directly from the tank to the fuel pump...

Less fittings, less places to leak...

Thanks for the replies guys. My local Napa wont fab the line so Ill do what you suggest Bond-o. I like the idea of less fittings. Is it against marine regs to use hose clamps(worm gear clamps) on the new line that I run?

Nope,... That's how it's done, just use approved hose,...

some folks will double the clamps for piece of mind...

'n dope the threads on the fittin',...

Will do. Thank you for your help sir. Would Permatex Aviation Gasket Sealer be okay to use instead of pipe dope for the threads? It says it resists gas so I would imagine it's okay to use.

Re: Mystery fuel line ID

Copper fuel lines were standard years back. USCG regs required a "flexible" piece between the rigid fuel line and motor to allow for movement. Two male hose barbs (one at filter and one at fitting), approved fuel hose and stainless clamps and you are good to go! See if you can find "full flow" barbs.

Might be a good time to consider upgrading the canister filter to a screw-on water separator/filter system.

Thanks for the info Comegene. I ended up replacing the entire line from the tank to the filter with A1 rated flexible line. Never gave any thought to replacing the filter with the type you suggested. Ive always run with the stock filter canister type and havent had problems. Is the water separator type really necessary? If I keep my fuel and fuel tank in good shape between seasons do you think its really necessary?

New boats come with the wsff and recommended to change them annually; probably for good reason.

There are many other threads here on IBOATS where folks have problems and one of the things the experts recommend is to drain/check what the contents of the wsff is for troubleshooting purposes.

So "really necessary" may be subjective but maybe "a good idea".

Thanks Mark. They seem to be pretty inexpensive and Im sure I can find a way to mount one to my existing fuel filter canister bracket.
