How much pressure? How long? Is there any chance of making another problem? Will it go back through an electric fuel pump? What about the selector valve? Are there any other "watch outs?"
Thanks, Tom

Sir: remove the gas cap first. I have an inline filter in front of the selector valve and every time I change it I blow shop air pressure back thru the selector switch 2-3 short bursts. Then switch the selector valve and do the same to the other tank. I don`d know about your electric pump as to if it has a check valve?? I would suggest putting a filter in front of the electric pump.

Tom
I did not see any prior message to which yours is referring.
Are you trying to blow the filter socks off?

Someone suggested I do this years ago and I blew air into the lines. When I recently removed my pickups from the tanks to put in my in-tank pumps I found that the filter socks were still in place. They looked like new. I was also amazed at how shiny and clean the inside of the tanks were. No rust whatsoever.
