"Hi I have an aged Sealine wit
"Hi I have an aged Sealine with two recently fitted ad41b,s. One starts on the button and the other one consistanly needs priming as if the diesel ahs dropped away from the pump. I have fitted a non return valev in the supply line and new union in the return pipe which I am led to believe should stop this but it does not. Any suggestions please? Thanks Simon."
