Brief Description: LEFT TANK LEAK FREE - Yeah baby!
After a frustrating exercise trying to get the fuel cap to seal off (finally used duct tape, the rubber glove trick didn't work for me) and back and forth with the manometer going down due to temperature changes I think I have a good test. This morning (66F) after taping the fuel cap, I re-pressurized the tank and raised the water level to 2' above the tank side (Van says 2' 3") and when I came home from work it was actually higher due to the warmer afternoon temps 85F and 29.94 on the altimeter (glad I left a little room for expansion). Definately not leaking!!!! I'm ecstatic!!! I plan to leak the tank alone till tomorrow afternoon to get a good long test. Yippeee!!!! Once I'm sure I'll move to the right tank and do the same thing.
Here's a picture of the whole manometer rig.
Manometer reading at 0700am this morning - 2' above the tank side water line
Here it is at 530pm - note the water is above the line about 2" which equal 2'4" above the tank side
