Just updating some things here for my own reference after helping Kevin fill up his blog by asking a question there.
I bought a new fuel sending unit from Max Merritt. I had spoken with them first and new that it would be a different unit from the original. It worked perfectly in terms of the fuel gauge and is 0 to 30 ohms as it should be. However, it was 1.75 in too long.
My original is 6.5in long and the new one is 8.25in. My original measurement was taken to the bottom of the float as someone had patched the intake tube with rubber tubing which made it too long. But, it likely worked at one time due to the rubber tube being able to flex. Max Merritt said that the 8.25in is what their plans show it should be. That prompted the question of whether I have the correct 20 gallon tank for a 120 or the smaller 17 gallon tank for a 115.
I re-measured my tank the best that I could given the rounded corners and came up with 36x20x6.75 (4,860 cu in) which translates to 20.25 gallons. The extra 0.25 gallons is likely due to not taking the rounded corners into account.
So, I believe that I do have the correct tank for the 120. Now, just waiting to see what Max Merritt finds out and get it resolved. I will say that I'm really happy with their customer service so far.
