I've ordered a plate, but I'm pretty excited about this Type A ProSeal. Just ordered some from Spruce. I bought the pint, figuring the cartridge is only a 50% discount and there's a good chance I'll need it again.

Bluesky's trick for the back baffle is a good idea; I used a similar trick with Flamemaster pourable sealant (I used Flamemaster brand to build the tanks, too) on my -7 tanks. I forgot that you said the leak was at the outboard end, which gives good access through the filler neck. I used 1/4" nylon tubing with a coat hanger for a stiffener; the aluminum tube should be easier to position accurately.

With my amazing $140 amazon-purchased borescope, I was able to find what looks to be the problem:


I'm pretty sure I can get the ProSeal back there with a syringe and some tubing. But I'm struggling to figure out how to spread it around. I need some way to manipulate this thing from 8" away through a 3" hole:


I could do it with a colonoscope, but I don't think I could get away with borrowing one!

Or would it be because you DO know where it's been?

Had almost the same baffle leak on my -8 tank . I used a semco gun and cartridge filled with standard proseal, a piece of semi-flexible plastic tubing and a plastic threaded plumbing union which threaded into the end of the cartridge. Use a #10 solid copper wire as a stylet and practice before you mix any sealant. Use gravity to your advantage and it should flo out fine. Worked out well for me...Good Luck

don't borrow the scope, bring the tank into the O.R.
