ebinmaine 80,628 #1 Posted 9 hours ago Several years ago I was contacted by a company in Plymouth New Hampshire called Small Engine Barn to help with some needed Wheelhorse parts. A few weeks ago they had a fella named Chris walk in looking for help on a mid 80s Kohler Magnum 8 fuel cap. The industry standard caps are almost always 1.5 I.D. or 2 inch plus. There are some variants of the M8 with a 1.7 or 1.75 I.D. AND a shallow 1/2" depth. Chris was referred to me by the local shop and we texted back n forth a bit while both of us did some internet searches. I did find a thread here that shows Kohler numbers that are expensive and tough to get. Chris came up with an Ariens part number of 03181900. This cap has a built in guage. Trina's Sparky tractor has that engine. I got curious to know if it would fit so I could leave the info here. Yes. Now Trina has a working fuel guage. I believe I'll order another one and try to modify it for use on the metal tank in my 1974 C160-8 Cinnamon Horse. The bottom would need trimming so "E" wouldn't read right but the rest would be correct. Some pics. Old cap. New cap with guage. Side view. 1 2 1 Share this post Link to post Share on other sites
Sparky-(Admin) 26,309 #2 Posted 1 hour ago Fuel gage would be nice! Plus accurate since the fuel cell is a “block”. The fuel gage on the under seat fuel tanks is far from accurate with its goofy shape 1 Share this post Link to post Share on other sites

The "bottom" of the OE tanks being at varying levels makes for an almost accurate 😛 guage reading below maybe a 1/4 tank. I'd have a similar issue with the roundish oval shaped tank in Cinnamon Horse if that adaptation goes. But at least I'd have a rough idea. Share this post Link to post Share on other sites
Sparky-(Admin) 26,309 #4 Posted 47 minutes ago Even the dashboard fuel gage in my 520-8 isn’t accurate. It’s really just a float still so shouldn’t expect any better accuracy from it. 1 Share this post Link to post Share on other sites
