Has anyone changed from the presto light HYC 5005 pump to the oildyne 38998–007 pump per piper service letter number 1165. I have a piper Seneca 2 with the HYC 5005(105476) pump and I’m tired of fixing it at the cost of almost $4000 now and the overhauls are terrible, they may be last a year. Just looking for anyone that can give some advice on this part change.
