Fuel tank plug

[VIN18M]

Hey guys, I’ve got a very slow leak from my fuel tank plug. I’m pretty sure these are the same as the GSR/Evo plugs. Anyone know where to get them? I was just going to head into my local auto parts store and get them to match my one. Alternatively I was going to just add a washer.
Should be right, but if anyone can steer me in the right direction that’d be awesome.

Plug on the underside of the tank?

The one that screws in?

If so get some plumbing thread tape and use that.

That’s the one. How’s plumbing tape hold up against e85?

It will eat it.

Maybe neoprene

My thoughts exactly.

I think I’ll just replace the washer with a new copper one and see how that goes.

Copper crush washers will do the job.
