gas caps

[midnightrambler]

Does anyone know what size the gas caps are? 1-1/2?  I need to change the plastic one on my main tank.  I changed the saddle ones years ago to ss.  Don't have my boat here but want to order new ones (base and cap). couldn't find the info or the old caps..

Yes, 1.5". I used this one, love it. I think it's required/recommended to ground all stainless, which I did, but every time I replace an accessory on my boat I look for stainless if it exists.

  No corrosion, no sparks, no keys, easy to replace o-ring, $13 .  (Hard to lose the cap, but if you did- $9)

   This is probably my favorite, as it's "classy", but does require a ground wire.  https://www.amazon.com/dp/B01EXZ3ARW/ref=sspa_dk_detail_0?ie=UTF8&pd_rd_i=B01EXZ3ARWp13NParams&s=sporting-goods&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw&th=1
