Replacing a fuel cap

Recommended Posts

sic0048

Well I was dumb last weekend and drove off before screwing the gas cap back on.  It broke the chain and is lost in the lake somewhere.  So I need to replace it.  I know replacement caps are available on Bakes for about $50.  

Does anyone else know of a better place/price to buy a replacement cap (for a 2004 Response LXi)?  Does anyone know how far down the original chain was mounted in the fuel hose?  The chain is not visible from the outside, but I assume there must be a piece hanging down in the hose.  I'm wondering if I could fish it out and install a new, longer chain where I could place the cap in the boat while fueling.

I know the current replacement caps come with a small wire instead of a chain, but the chain was ideal because it allowed the cap to be screwed on without kinking the chain.  I can't think of a way to attached the retainer wire where you could screw the cap in without kinking the wire up.  If anyone has an idea, I'm all ears!

my 04 (not an lxi) has the chain attached 2" behind the threads for the cap

looks like a screw (not accessed internally) secures that chain

To access the screw that holds the chain to the filler neck you need to remove the fuel hose that is attached on the inside, then remove the 3 Philips head screws and take off the filler neck.

West Marine sells a black plastic gas cap that fits. It even has a lock and a key, but looks kinda odd. It’s cheaper tho. :)

A replacement cap does not thread in completely on any boat built before 2007. Older generation caps are not available new.  I do not like the looks of my replacement cap when installed.  It falls about a 1/4" short of threading in completely.

Sort of unrelated. I have a 2" abs pipe cap in the my glove box for when I eventually do this.  It can serve as a temporary gas cap.

Is the problem that the new cap has a longer threaded part?  If so, can you just saw off some of the threads?  Or maybe cut them off on a lathe?

The gasket seat is a 1/4 deeper on the new caps.

You are probably more correct than I am. I know mine is the correct size.
