Lost my diesel fuel cap overboard while refilling.
Need a replacement. They are the stainless steel type.
Any suggestions where to get them? Catalina Direct doesn't seem to have a match. Saw this on Amazon https://www.amazon.ca/dp/B000XBMAOA/ref=cm_sw_r_cp_apa_glt_i_G1QTDZTRCEQME4E1RAFP?_encoding=UTF8&psc=1
I got this one from Catalina Direct. (two for the water also)

Saw those. However, I have the 2 prong style and CD mentions those are only a direct replacement for the plastic types due to thread pitch.
I would see if any of your other fill caps will fit. If they do, take that cap to a Chandlery and match the size/thread to a new cap. If you find one that fits and they won't sell just the cap aline, you may have to buy the whole fill pipe/cap set and toss the pipe.

Is it the full-cover type (CD type) or the insert type (sits inside, not covering the whole flange?) A picture of the flange or similar fill cap?
It might be an Attwood or SeaChoice or SeaDog size/thread pitch.
If you have another similar fill, measure the pitch and diameter. My "insert" type caps are Perko and the same as 1-1/2" NTP thread.
pby : If you fail to find a SS cap that fits, just go ahead and change out the the entire fuel fill to a new one that has a chain that attaches to the cap!!
It's not that difficult on a MK I C34, but on a MK II you might have to remove the aft cabin post side panel.
A thought

Looks identical to this. The screw fell out of the retaining clip, and of course, before I can get a new screw the cap goes over board...

It might come to that! :) I've had the panel off before so I believe the access is good.

OK, that's the insert type -- same as mine. They sure look like the Perko, but mine are black plastic not stainless.
Is it 1-1/4 NPT? (I THOUGHT mine are 1-1/2" NPT but maybe I'm mistaken.)
Measure what thread they are to narrow it down -- Perko and Whitecap and Seadog and Attwood all look similar but I believe some are 1-1/4 vs 1-1/2".
No sense guessing which to buy. worst marine, ebay, scamazon all have them -- once you decide on the size.
Doesn't the link say this?
Stainless steel deck fill marked for gas. Uses 1-1/2" hose, 1-1/4"NPT CAP.

Yep, but he said: "it
LOOKS identical." Not, "it has the
same thread as mine."
Spoiler alert :shock: These four caps
LOOK like his (and mine) but they have four
DIFFERENT threads.

I'd have to think it makes sense to measure rather than guess from a picture :cry4`
but as always, his boat his choice.

The local chandlery has something I can at least compare. I'll pull one from the water tanks, which I know are the same as I checked, and match it up. If that doesn't work I'll use a more science based approach and measure it! :)

You could alternately take one to a big box and see which female threaded pipe fitting it screws into. Or vice versa, buy 1-1/2 and 1-1/4 male fittings and see which fits the deck fitting. The other common sizes are 1-7/8" and metric, but I'd think those are way outside chances.
Good luck! Let us know.

Great suggestion! Thanks!
i remembered i had this in the garage, it came of my Mk1 when i pulled all the deck fills (i think, or it might have been in a spare parts box from the PO). if it fits, you're welcome to it

Thank you for the offer! I suspect the shipping would make it a wash with a new one. I was able to get a replacement at a reasonable price.
I was able to find a perfect match. Pictures attached. It was listed as a BMS Product but I there is no matching information on the box. Sorry I don't know the thread information. I just took a chance.
Very cool, AND on sale. :clap :clap :thumb:
It's 1-1/2" NPT thread.
Just for the archives here's one brand that will replace just the cap:
