[renaissance man]

Thanks Tony. I'll check that today. I blew each line out with air the other day from the tank (including the pickup) all the way to the fuel pump. Didn't blow out the line from the pump to the carb cause at that time it was squirting like a firehose from the primaries. I put an inline filter (clear) in the engine compartment just before the pump. But you are right, when it operates properly I get 5lbs of pressure.
