Hi all
I have a 1993 Martinique 3600 and am having issues with a fuel problem on one engine
The engine will run up to around 3000 rpm but anything over that and the pressure drops right off from the normal 6 psi down to zero
I think there’s a blockage in the pick up as I’ve changed all the filters with no result
Could it be a venting issue or do I need to pull the pick up out?
Has anyone had a similar problem
Thanks in advance

There is also an anti siphon valve where the fuel line connects to the tank that may be clogged. They are easy to replace. I tested the fuel pickup by blowing a little air into the fuel tank and listening for bubbling. That might also clear any blockage in the fuel pickup.
