Deleting Stock fuel filter and housing

[Burn Down]

If your in the sticks sometimes fixing the lift pump is not an option. If you made a bypass line around the lift pump with a one way check valve or ball valve, you could get home if the lift pump died. Still need a way to prime it if you take the factory filter head out.

This is what I will be doing this spring, remove the factory filter & run a Cat water seperator filter & A 2 micron Cat fuel filter with hand primer just incase.

so if the Air Dog 2 goes out the stock CP3 will or will not be able to still pull fuel with the air dog 2 still hooked up?

No, the airdog is not a flow through design, IIRC.

so if the air dog 2 goes out you would need to by pass it for the CP3 to pull fuel again?

Yes, the Airdog IIwill flow. IT IS a flow through design.

Just doing this won't work. You also will need to crack a line somewhere to allow flow. No pressure differential, no flow.

The CP3 should be able to eat the air bubble, it just can't suck fuel from the tank if there's an air pocket at the gear pump. Think of it like this. The little bleed screw isn't on the CP3, it's on the filter. There's about 18" worth of hose that could have an air bubble in it. When you bleed the air out of the filter, you pressurize the line so that any air bubble is pushed through the CP3 and the fuel gets to the gear pump and is then able to be pulled from the tank. At least that's the way I look at it. I could be wrong.

FPRV is what? so to bypass the stock fuel filter and delete it you would go from the FICM (banjo fitting)to the CP3?


THANK YOU FOR THE HELP

I agree and fwiw you can get filter housings with a primer on them I know my raycor has one and can also have a bowl heater if desired
