Re: Partial blockage in fuel line
Since the problem remains when you switch tanks, the problem must be in the fuel line from the engine to the manifold or in the fuel manifold itself. Maybe the valve is plugged, or the copper line to the engine.
Do you have a priming pump in the system before the Racors?
Re: Partial blockage in fuel line
Sorry for the delay; my bodies engine needed a Pacemaker implanted! We will be going down to Marathon in the Keys from Lauderdale in several weeks and will try running the engine on each filter individually. Maybe that will point out something useful. Your input was gratefully received.
Re: Partial blockage in fuel line
A Pacemaker? for all that effort, you should have gotten a Hatteras..... LOL Glad you are okay.
Re: Partial blockage in fuel line
We will be at Banana Bay from the 12th through the 18th. If you are nearby and need a helping hand for a few hours I could possibly help. That is if you catch me before Rum:30 which can occur at any time of the day :cool:
Re: Partial blockage in fuel line
I had a blockage (well, the boat had a blockage) problem several years ago. The engine would bog down from fuel starvation and then surge. It turned out to be a paint chip in the fuel line that was stuck up against a ball valve. Of course I replaced or inspected every section of the fuel system from the tank forward and from the engine backward. The ball valve was the last thing in the system that I hadn't checked. Obviously, that's where the problem was.
Re: Partial blockage in fuel line
This is a last ditch idea but sometimes old ball valve handles strip and appear to be open (or closed) when they're not.
