Anyone know if there is a Kelch gas cap or something similar to replace the Polaris OEM gas cap with gauge on a Pro RMK? Appears the OEM is 14" but I'm only finding 13.25 or 13.5" ones like this: https://www.denniskirk.com/kelch/screw-on-gas-cap-with-gauge-54-1815.p186000.prd/186000.sku
the dome on mine is cracked in multiple places and leaks when turned over so was curious if I'm stuck with $45 poo cap or if there's an alternative.

TIA

If you want it accurate.... you are stuck... if not... go with the 13.5"

Amazon prime has the 13.5" for $20 shipped.

hmmm 1/2 the price but I'd have a "reserve" tank when I hit (E)mpty given it's .5" shorter lol. Thanks for the info Mountainhorse!

Also worth noting... with a Kelch gauge cap.... how the helix is wound also has an effect on what the gauge reads.

"off the shelf" gauges are linear in how they read... Proprietary gauges, made by Kelch for the OEM market are custom made in both length and how the spiral is wound.

A linear gauge is good for a rectangular tank.

This comes from a convo I had a few years back with an application engineer at Kelch

Note: the helix on a Kelch cap is the center flat 'twisted' ribbon.

thanks for pointing that out... side by side photos and they certainly are different with the twist, etc. Thanks again for the info, much appreciated!
