Need TropiCal diesel fuel cap info

I tried to use the high flow fuel pump at a Love's a couple of weeks ago. My vent doesn't flow enough air and when the pressure got high enough, I got sprayed with diesel gushing out of the fuel filler. In my haste to get cleaned up, I forgot the cap and tool. I called to Love's just a couple of hours later and they found the cap and tool right where I left them and brought them into the office.

Unfortunately, they apparently don't have a lost and found process and someone did something with the cap and tool a few days ago. No one knows where it went, so I need a replacement.

The cap is a disc approximately the size of a silver dollar with threads around the perimeter where it screws into the fuel filler flange. It has two "blind" holes in the top, which the tool engages to unscrew the cap.

Our RV storage is several miles away and I haven't had time to see if the flange has the manufacturer's name on it. If someone can check their fuel cap and/or flange to see if there is a company name or model number, I would greatly appreciate it.

As for Love's, I've already noted where the Flyin' J fuel stops are located along I-90.

It sounds like a cap I got for an old truck relocated fuel tank. It is a marine deck fuel cap. check here and see if it resembles any of these.

National used fuel filler caps from the marine industry. Try this link via a Google search and you should be able to find what you need.

Many thanks. The lost cap looked a lot like the marine caps in the links provided. Now to figure out what size / thread.

West Marine in Edmonds has what you need. Fisheries Supply also has them. You should be able to order a replacement cap without having to buy the entire assembly. There are two pipe sizes. If you used the Truck nozzle I suspect you have the large diameter fitting.

Mine is the 2" version. I know National used the 1 1/2", but I believe only on older model Tradewinds.

Here is a source for either one:

Sea-Dog, Hose Deck Fill, Cap Only

Just to close this out - the cap is a SeaDog 351391-1. It was an in-stock item at my local marine supply store.

It appears that the SeaDog locking cap would also fit. It looks like SeaDog doesn't sell just the locking cap - I would need to buy a complete filler neck and cap set.

I actually do some work for SeaDog's plastic molding subsidiary and need to invoice them soon. I may try to barter some of my time for a locking setup.
