Fuel Cap O-Ring

[MN Ryan]

Anyone happen to know the size of O-Ring used on this style of fuel filler cap? I don't see it on Nautique Parts, and I think I'll ruin them if I try to remove to measure.

Replaced mine a few years ago, size I used was 1 3/4" ID, 1 15/16" OD, 3/32" width, got a pack of 25 viton o-rings off of Amazon cheap.

Thanks, @WakeHawk!

For anyone interested, I tried the -132 size o-ring, which is nominally 1 3/4" ID, 1 15/16" OD, 3/32" cross-section. They're close, but not quite right (I now have a bag of 100 because I apparently missed that second 0 when I ordered ).

I think the -223 size is going to be the ticket (1 5/8" ID, 1 7/8" OD, 1/8" cross-section). I'll report back when they arrive--this time I didn't order 100!

For sale, 99 count, size 132 o-rings, for cheap, willing to split lot count.
Please contact MN Ryan for pricing and shipping...

lol

None of us has ever done that before, do you need any 16" cable ties..?

I figure I will just toss them out at a parade this summer.

Another swing and a miss. The cross-section was just a bit too big on the 223 size, but at least I only ordered 4 this time. One last shot--trying a 3x41 mm metric size. Wish me luck.

You got this MN Ryan!

Third time's a charm! For the record, a 3x41 mm o-ring is a perfect fit.

Link to where you purchased? I was just looking at mine…. They need to be replaced.

I got a pack of O rings at Lowe's for mine. There was one large ring that fit perfect.

MN Ryan, wait, that's only 2, where are the other 98 rings? lol
Good job, I know even though it took a few swings, others will benefit from your batting practice...
