Held my breath and used the deep 26 mm was worried the angle might break it but luckily it didn't have to get a lot of force and I got it loose put the new one in The irony is the new unit took a 24 mm LoL.
At first I thought it was the wiring so I clipped out the bad and put in some new mode so I'm yesterday before a downpour and after the motor had been running a while mowing the light come on so that I knew I had to take out the sending unit.
Did a test run mowing little while ago light never come on.. sure glad to that I'll feel better after I do some more mowing.
I'll be SOL if it's requires more than that it's a gray market L1501. I sure don't have the capacity to do rebuilds. Besides the expense expense In this current economy doing that. Might as will get another decent used compact.
