Does that mean my stock Merc 454 mag stuff with a good filter? I'm running aeromotive pumps and will be making about 550-600HP with a carbed procharger set-up.The inputs are 1/4" NPT,what's the best way to go from #10 AN hose coming out of the pump to two 1/4" NPTs?Some type of fuel rail?Then it's back into one #10 into the regulator, then out in #6s to the carb box.

anyone,anyone??

I don't know if the Merc one is good enough, but if you have a fuel pressure gauge you can see for yourself. There are some pictures on our website that show NEVRENUFF's Procharger install. He used a big Keith Eikhart fuel filter with his Aeromotive pump.

The stock Merc water separator will be too restrictive. Go with the Keith Eickert unit. It's a work of art!

Are you talking about the one with the FRAM filter on it?
I was going to use 2 lines in and 2 out on the Merc one with a good filter.??Who carries the K.E. stuff?

It's cutting it a little close but seems like if one 1/4 line was enough for 365HP then 2 should handle 600?As long as my filter is free enough. Can I use the big fram filters on my Merc stuff? My pump is a little overkill for the power I'll make so I was hoping it would overcome a little restriction.I'll have more in plumbing than the filter housing by running tees etc.I may try it and watch the fuel press guage,,,hell I don't know

Whoops,that big orange thing is the oil filter huh?Wish I could take that back

my procharged hp 500 with aeromotive pump has the large hight flow filter housing that cp performance or eddie marine sells it has 1/2 npt in and out and takes a fram 5062m high flow filter which wont screw onto your housing.i would get that set up thats all you need.not as fancy as the KE set up but less $.

You can run two stock separators in parallel. That's the inexpensive way out.

On the other hand, there are several good quality high flow units out there. Check jegs or summit.

Get the best filter that you can afford. Why would you chance frying your engine over a $100. part? In my opinion: "maybe it'll work" is not good enough. I use the new Hardin filters (similar to the KE part) and -10 (1/2") lines through the filters and into the pumps on my blown engines.
My 2 cents.
