Is there a fuel/water separator that is a better choice than using the stock replacement for a 502 magnum? I have a helper pump before the separator and would like a separator that is okay with pressure being pushed through rather than simply suction. I don't know if the Merc one is rated for pressure.

Thanks for any help.

Our FloMax 300M is a direct conversion and will allow for mounting on either suction or pressure side of the fuel system. Check out our website www.ramcoperformance.com or call 888-476-1320 if you have any questions.
Thanks

At this time I am looking for a simple spin on replacement for the mercury plumbing.

RACOR....

I second the Racor you can get any flow rate you need, opinion I do not feel a feul filter should be put on the pressure side to me it adds an un wanted risk.
