The PV tank has a small diameter pickup tube bent down pointing towards the bottom of the tank. I’m concerned that if I pour gas tank sealer into the tank, it will plug the pickup tube. Those who have sealed their before, how did you avoid plugging the pickup tube. The level sender unit opening at the top is very small and does not really allow access to the tube.

Background:

Have the tank out and cleaned it on the outside, found some rust holes. Since the tank was dried out and very rusty, I threw in a chain, added water and agitated it. A lot of rust was washed out.

Next I decided to try electrolysis. I got a large tote and submersed the tank. It’s currently being cleaned. It may take a few days, but the water is already very dirty and I had to clean the anode a few times. When I have a clean anode, it pulls 4 to 6 amps from the battery charger. Over a couple hours the current goes down to nearly zero until I clean the anode again.

So, any ideas on how to keep the pickup tube from being plugged when I finally get to pouring in the sealer?
