Fuel pressure problem

[tsubaki]

You don't know how hard we beat our head on our problem.
We took apart everything from the pickup tube out the fuel tank all the way to the fuel rail.

Oh, don't leave out a possible vent problem.

The vent is a bit corroded. We were about to replace that and the fill tube anyway. The fuel cap is cheap plastic and we want to upgrade it all to stainless. Sounds like a project for the upcoming weekend.

phat, that's easier, cheaper and neater than what I was suggesting!

I may just have to check that out. I know that I mounted it exactly per the specs. I may try filling in the space with silicone first to see if that gets rid of it. If not, this is an excellent idea. Thaks Phat.

If your hearing an alarm before it runs out of fuel, then that is the fuel restriction alarm going off. It takes about 3-4 inches of vacuum to set it off, so that is a pretty noticeable restriction. Check your vent, lines, and filters out for the restriction.

Thanks Ferm. Let me ask you this.

I'm going to try and describe this accurately. When I pull the engine cowl off, I'm staring at the black air intake, that says V6 on it. When I'm looking aft from the boat, on the bottom right corner is what appears to be a vent line. I was having problems with that line a few weeks ago being cracked. It appears to me that it may be kinked now. Could that one line be causing the issue?

The issue immediately goes away when I pump the gas ball and turn the engine back on.

If you didnt fill in that space yet between the transducer and bracket I guarantee that will fix your problem. 'your description is EXACTLY how mine was throwing a rooster tail until I filled that space in.

Thanks RWilson2526. That's what I'm going to try first before drilling more holes in my boat. I'm reaaallly hoping that it fixes the issue.
