Excalibur 330 Fuel System Troubleshooting & Info

[bionaraq]

Thanks for this post!. Will look for the upgraded connector on the FCC and since my low pressure pump is whining I'll order one. Anyone have the part number for it?

To close the loop on anyone following my previous post on this thread, my issues which I would have sworn where fuel related ended up being fixed by new rotor cap and plugs. I was only getting about 60% of power when under a load, so assumed it was starved of fuel. Thanks for feed back though

Just to note the troubleshooting steps in the OP's post can be applied to the 1996-2002 GT40 engines as well. Those have an almost identical fuel system layout as compared with the Excalibur. The fuel pump relays are located on the rear of the engine on the GT40.

Did you have to take it completely off to get it apart?

[jstallings]

I got it apart but sadly was not the problem, I am thinking it is something electronic now...

[MTRBTR]

I could have gotten it off. It’s not that hard. Mine was especially tight. Instead of risking breaking something I left it since my boat seems to run fine.

Really? I have never removed before does anyone have any tips on removing? I am also going to borrow a fuel pressure gauge and see if I can get a reading on pressure this Saturday, does anyone have experience using one of these gauges? Thank You

[MTRBTR]

Let me know how it goes. I couldn’t get mine off.

[jstallings]

I believe it does! I will check that! thanks so much.

Does it have the little prescreen filter in front of the FCC? I have heard those can plug up. It is a little black canister right in front of the FCC and there is a little screen in there that can be flushed or replaced.

Hello, could someone following this thread help me? I have a 2007 SV211 the motor starts and runs smooth but performance has been dropping. I purchased the FCC filter and inline filter, last weekend and change the FCC, apparently my boat did not come with the inline filter from the factory. The new filter did not help the performance (perfect pass is off), the engine only revs to 3400 rpm under load, but will rev freely in neutral. I believe it is being starved of fuel... there is no difference in performance when the throttle is fully on and when it is push down 60% of the way. What would be next step to take, (pressure gauge on fuel line - if it is low pressure) what else should I check. I keep my boat on a lake an hour and half from home, so when I get there I want to be prepared to fix whatever is wrong if possible (need to order parts soon). Any advice would be great, TIA!

Ballast tank drains. They originally had a plug in them. I added the valves and barbed fitting for draining and winterizing.

What is the white PVC valve with the lil nipple on the red hose for (under the FCC)?

Nice write up

FCC showing connector that can be upgraded.
