My fuel pump has crapped out. No numbers, names or anything to identify it. Its aftermarket for previous 4bbl. I am putting 0-80559 600 cfm Holley marine on. Any suggestions on pumps, gph etc?
Engine: Volvo Penta 5.7l gl Carbureted. Thanks

I have been through two holley marine pumps-junk!Bought the mallory marine and never had a problem again.

I have had the holley marine pumps for 2 years and think the new fuel left untreated is to blame for most problems. My buddy runs his drag car w/ holleys also but on race fuel w/ no problems. BTY I treat my fuel every time w/ marine Stabil!
