Racor pre-pump fuel filtration

[lakailimited06]

When I get some free time I plan on installing a Racor pre-pump water/fuel separator. My question is what micron rating should I run pre-pump? Also what is the stock fuel filter rated at? I've been running the Wix filter/cap since I've owned the truck if that makes a difference. Also will adding this pre-pump setup put more strain on the stock fuel pump?

The mc fuel filter is 10 microns absolute, wix is 14 nominal.

This guy runs a 2 micron Dahl prepump which racor where you thinking?

Regardless I would do the prepump mods regardless...

And a fuel pressure gauge would not be a bad idea imho

I'm running an isspro ev2 fuel pressure gauge. There are quite a few Racor filters than people seem to run. This guy" Installing the Raccor Fuel Filter/Separator " uses a fuel/water separator from Racor that's designed for outboard motors which I wasn't sure if I could use a gas W/S for a diesel W/S. I didn't know that the stock pump required for fuel flow 15/30/45 GPH? Also I'd prefer to go with Racor being that I work at a Marina and we have plenty of Racor products in stock and get them cheap.

Iirc the stock fuel pump is 32 to 36 gph for a stock engine. Additional fueling will require additional flow to meet demand.

ok so if i run a 2 or 10 micron pre pump filter rated at 45gph or more i should be ok i guess. Still can't seem to find out whether I can use one for gasser or not.

Looks similar to the set up guzzle ran prior to his help pump. I am sure it would be fine. Personally I prefer something like the Baldwin BF1212 just cause it is more locally available near me but I don't see why this set up wouldn't work.

do you see anything wrong with the setup i want to run? i keep reading/hearing about psi ratings and flow ratings not being enough for the injectors or what not..my 7.3 is stock besides muffler delete, DIY intake, and gauges..im hoping a 45gph would be enough for stock setup..last thing i want are my injectors not getting enough fuel.

At 45 gph you still have an extra 7-10 gph over a stock pump. Your fuel pressure gauge will tell you in a hurry if aren't getting fuel.
