Cleaning out fuel tanks

No worries, back apart AGAIN! fixing a fuel leak?

 

I filled this one up with ER today. Put a rubber plug in the drain at the cap opening so I could get the solution all the way up and above the fill lip. I normally put the tank in my big tub, but took a shortcut today. No leaking so far!

 

Not sure about your experience, but don't leave the EV on the nice painted surfaces. I missed a spot that dried on the nice paint and etched the paint. Now I keep towels and cleaners next to my work. hahaha

 

Thanks, I usually wipe the tank with a damp cloth before leaving it - especially if any spilled on the paint. I use a big funnel today and didn't spill a drop!
