Re: 496HO need help, serious problem
Dont have a diagram, and you wont need it. Right front lower.
Meaning Right if your standing on your motor looking forward.
About 5" long pump, line goes in line comes out, screen in front traps all the crap that the builders leave in our fuel tanks as they sit on the shelf. I hope Fountain and others will learn from this. Mine was full of bugs and metal shavings, bugs living in the tank and shavings from someone tapping the tank for fuel line and figuring all that metal wont hurt any thing. Good luck, JC

When you guys see a clogged fuel pump screen(or when you buy the boat with the 496 system).Get a Racor S3232UL (10 micron) or equally and be done with the problem.

Re: 496HO need help, serious problem
sorry guys, call me dumb, im still not sure i know where this thing is or how to get it apart, i know there is a pump down by the fuel/water sep, and there is another one on the other side thats in a big black plastic cover that you have to remove to see the pump, has some big hoses connected to it as well, how hard is it to get to this screen? also how often do you check it or clean it.. whats this raycore thing?

Its the one by the fuel /water seperator. Take off lines and remove pump look in the end that was facing forward. Suprize! a pile of crap. I cleaned mine 2 years ago and never touched it again. Let us know what u find, JC

Boost pump. Went thru two of them after experiencing same problems and verified by fuel pressure gauge. Seems since the ethanol thing began the crud and water in the tank seems to have fried both pumps one right after the other. The first one went suddenly. The other croaked slowly or intermittently.
Good luck. I would think other than boost pump replacement (easy to do btw) the next step would be to examine the condition of the injectors.
