Most boat stores also have the Moeller mechanical gauge 12"
When you refill the tank you can see the gauge. When it indicates full you can still put about 2 USG extra in the tank. Be carefull with the last gallon, when you hear the "gurgling" sound the tank is full.
A special thanks to Marty Santic and John Bender for coming up with the fuel gage fix. Nice to see Vans picked it up and incorporated the same exact gage into the kit.
It is this one for $52. (Was $55 when I bought it.) http://www.amazon.com/Moeller-Marin...1384278039&sr=1-6&keywords=moeller+fuel+gauge Model 035754-10
The different sizes come in the same cardboard-plastic bubble pack, with all the sizes listed on the right side of the pack and the size contained "checked" - it is the 12 inch size that is checked (but the model is -10 as shown).
