I have a saddle tank out of a 48 Chevy that I an installing on my COE. Does the line pickup line in the tank have a check valve in it. I'm trying to clean the line and can't blow nor get a piece of wire through it. The tank had some junk in it but was in fairly good shape. I also put 100 LB psi through it, no luck. I'm attempting to work the line from the outside in (reverse of the way the gas would go).
