Because fuel drains back
though an Andair non return valve from the header tank to the wing tank(s), I
replaced the left NRV last year thinking that was the problem side. Fuel drains
still from the header, and instead of replacing the right NRV, I thought I
might remove, clean and replace it before taking any other action. The left NRV
which was removed was quite corroded under the ball, and the LAME said “I’ll
fix it for ya” and that was the last I ever saw of it.
So any suggestion for the
best means of cleaning the NRV seat, such as steel wool?
Thanks and cheers
