I know you may not want to hear this Mark, but, if it were me, I would remount that filter and pump to get it at least even with the sump outlets...you can build a box around the pump if you dont want all the tire crap and dirt up around it...

Jeff,
I know this is the logical answer, and I am looking at how it could be mounted, with a minimum of changes, or mods, to the parts that are already painted!
Is there and electric fuel shut off that has -10 AN fittings? I could replace the check valve with that and .........
Thanks,
Mark
