Oscar,
I will measure mine in a few minutes, or I can bring over my filler neck to make a template if you would like. Bob |

Oscar,
There are 8 evenly spaced holes (45 degrees apart) Bolt circle measures 3.224" dia. Bolt hole diameters measure 0.234" (with paint on the ID of the holes of my filler neck). The opening of the tank measures 2.808". The gasket surface OD measures 3.910" I measured twice, if you want me to bring the tank and filler neck over to transfer the pattern let me know. Bob |
