Diesel fuel cap

[dervin]

Where can I buy a Perko fuel cap for my 41’ 1997 Maxum express?

West Marines should have it.

I just bought one for my water tank. There are two sizes. On my boat the smaller size was for water, the larger size for pump out and the diesel deck fill. I ended buying a replacement for my water and a spare of each size, just in case.

I bought them at West Marine (in-store) however I can't find them on their website.
