Deck key isn’t turning the diesel fuel cap.

Needle nose pliars should do the trick, more leverage.

That’s the saddest key I’ve ever seen.

StatisticalMan@reddit

I have a key like that on my keyring. Keeps it handy and if caps are opened regularly they aren't that tight. In OP case though he is going to need something to break it loose first.

It’s the only one I could find at west marine 🥲

[-]

stumanchu3@reddit

That’s where all the problems start. Please tell me you didn’t pay $400 bucks for that, west is a rip off.

[-]

icouldnotpreventitVL@reddit (OP)

They definitely are a rip off honestly their prices are appalling but no, I only paid like six bucks for it

We got the same one free from a vendor at an event at our local boat shop. Just tried using it on the waste tank this weekend and had the same results as you. It got chucked. Sorry you wasted $$ on it. I'd take it back.

Deal of the century from West Marine! I’m sure you’ll figure it out. Happy sailing and fair winds to you skipper!

[-]

icouldnotpreventitVL@reddit (OP)

Thanks 🙏🏾 🤙🏾 I’ll post when it opens and what worked.

WM is pretty fairly priced in an environment with razor thin margins plus you can price match.

[-]

deltamoney@reddit

You can price match

[-]

Wierd657@reddit

WM also has the Davis stainless key, their own stainless key, and the Groco spanner wrench all next to each other (if in stock).

Use a wrench, not a key. This is what you need:

This is the answer. Pricey, but worth it.

[-]

Foolserrand376@reddit

this is what you use. if this doesn't do it then you may have to go down the replacement road.

[-]

Lopsided_Ad_5152@reddit

There are 2 Perkos at most West Marines. You got the ones with the "tits" too far apart. The other one looks exactly the same except they are closer together. That's the one you need.

If you don’t have any luck using penetrant and/or a long handled deck key, you can drill the two holes all the way through stepping up to at least 1/4”, insert either two bolts or an appropriately size u-bolt, and then use any long handled tool of your choosing as a lever wedged between the two bolts. Once it breaks free, either replace the cap or clean up the threads and fill the drilled out holes with JB Weld.

Done it many times.

OK this is brilliant thank you! If all else fails I think this will be the way,

[-]

icouldnotpreventitVL@reddit (OP)

I have one of those but it also didn’t work? Just started stripping the metal on the plate.

[-]

nomadicSailor@reddit

New boat to you, 'eh?

You've just taken your first step on the incredibly rewarding journey of itty bitty jobs turning into a major project. Had one of those freeze up so bad that it had to be replaced.... That itself should be an easy job. But no, ended up replacing the fuel tank(s).

Have fun!

[-]

icouldnotpreventitVL@reddit (OP)

😂😂😂 you guessed it. Lmao! Yup this was supposed to be just a fuel line bleed and now I’m here. Thanks for the well wishes 🤙🏾

[-]

zhelih@reddit

Do you mean you are trying to turn and it is stuck? A bit unclear.

Anyway, if that’s the case, put a wooden block on top of the cap, hit it with the hammer couple times strongly to shake things up. If the cap is stuck, this will do it. Happens often after the winter.

[-]

icouldnotpreventitVL@reddit (OP)

Yesss that’s what I mean, it’s stuck and won’t rotate. I’ll give this method a go, thank you!

[-]

iddereddi@reddit

Any chance the tank is not vented? A little bit of under-pressure will suck the plug nice and tight. You can use an adjustable wrench to grab the cap key, put a piece of wood on the key and step on it to keep the key lugs from popping out the holes.

[-]

icouldnotpreventitVL@reddit (OP)

That could be a possibility. I’m trying to figure out tho that these levers do 🫠

[-]

Whole-Quick@reddit

Its possible the O-ring under the fuel cap is tired and making the filler cap very sticky to open. My old boat did that when I got it.

A new O-ring every decade or so will prevent that issue, or worse letting deck water into the fuel tank.

Ok-Bar-8785@reddit

What the he'll is this? More picks please. Where are the pipe's coming from / going after this area. How many engines? For a 2 tank set up It's common to be ablento select the tank for feed and return. In the photo it looks like the tanks are linked which is odd.
