who lead the horse to the water on the phone calls here I got to get some credit here a tad yes or no ? - always check fuel pressure ESPECIALLY on new rebuilds and install new filters once per year whether one uses their boat or not.

a decent fuel pressure tester is maybe 30 to 50 bucks - cheap tool to have for whomever works on their own apps

at spring commission always check fuel pressure after lay up. Fuel pumps and regulators can go bad just sitting idle for months and is not uncommon for that to happen
