40 mm fuel fill cap

[BergeronWarren]

We accidentally kicked our fuel fill cap in the ICW at Coinjock, and after a few failed attempts to find a replacement, it has become clear that our 40 mm caps are rare. Long term, I may replace the whole unit. For now, I wonder if anyone has advice on where to find a replacement cap?

Until you find the proper replacement.... You obviously need to keep water out at all costs.... It won't be pretty, but I keep a few of these rubber expansion plugs on the boat...

Depot/Lowes/Auto supply....

Good advice above........How about the boats original builder, or one of their dealers. Also, look at the other fill fittings on the boat, will one of those serve as a temp replacement? See if you can find the makers name on the part itself.

Great advice also!

BUT!!!!!!

Make sure you label the cap....

"No longer the water fill.... Anything other than diesel fuel will cause the skippers head to expand to dangerously large proportions"

Thanks for the response. I did use the water fill cap of same spec to protect fuel and now I have duct tape covering the water tank fill. The boat is a Lord Nelson built in 1983 in Taiwan. The manufacturer has long since disappeared but the previous owner may have a spare in the garage. Let's see what turns out. Thank you.

You got it man!

LABEL THAT TEMP DIESEL CAP!

Well, if the PO's garage has burnt down, you might try to determine if any other builders in Taiwan might have stock. Obviously, the boat builders do not manufacture deck fill fittings, they purchase them from vendors in that line.

Happy Mdrsailor, why label it if a replacement is obtained? Just use the new one in the water fill deck fitting.

Just saying that often the "cap" is cast with... water.. diesel... waste... If it is the surround fitting, you're good!

I had a similar problem last week.

From what you say it sounds like an 1 1/2"filler cap, I have just bought the one below and across the threads it is 41mm, the cap top is 48mm dia.

ASAP is a very well known company in the UK who also export, I use them a lot so no problems, also helpful by phone/e-mail etc.
