Once that is complete I will start the baffle work. I will not spare the proseal because the last thing I want/need is to have to repair the tank once it is closed.

More Fuel Tank Progress
Tanks are complete except for baffles. I highly recommend the preliminary leak test prior to putting on the baffles where you fill the tanks with colored water to see if you have any issues which can be corrected. In my case the problem areas are shown below. The ones at the junction of the three pieces underneath the tank attach bracket are very similar type of joints to the corners of the baffles so lesson learned there. Get an inspection mirror and look underneath the j channel as well as under any joint to make sure you have a fay seal with NO small pinholes. The nut shown below has proseal around it but there is a very small hole where the sealant failed to settle. Liquid will find its way out.

tell me what you used for coloring the test water for the prelim tank test; coloring agent, mix ratios, how long it took to see the leaks, etc. . .

DeleteLooking back, I used regular food coloring. Red I recall, most likely around half a small bottle for both tanks. Because the leaks I had were large, looking back there was no need in my case to even put the food coloring in, because you saw the leak immediately. The intent of the color is if you have a very small leak you can tell if it is just condensation on the outside of the tank or actually water from the inside coming out.
When building look at all the joints on all the ribs and make sure there is no gap at all. Always err on the side of more sealant.
Feel free to write back if you have more questions. Mine did not come out beautiful but they are safe and functional.
