I have a Very small leak in one of my newly sealed fuel tanks. (Tank will decrease from 28” H2O and hold steady at 5” H2O on the water gauge.) This afternoon , I found the leak using Snoop in the corner of the TANK INBD RIB-Fwd where it adjoins the tank attach bracket assembly.
My plan is to thin some Proseal and try to spread it around the flange and the pull a very small vacuum on the tank. Lastly, I will scuff redcoat the area with full strength Proseal.
Two questions:
1. Is there a preferred thinning agent for Proseal? I’ve read that MEK or TOLUENE/toluol. With the latter being preferred. Curious if XLENOL would work also.
2. Pulling a vacuum: should I use a hand vac from the auto parts store and limit the vacuum to approximately 1 psi or can I use a suction tube and draw enough vacuum to weep the Proseal into the suspected area?
Thanks
