Manual Pump Bypass
I have never owned a Powerstroke before, just IDI engines and on all my trucks I always bypassed the manual fuel pump and installed an electric pump, can this be done on a Powerstroke? I have had to install pumps on Powerstrokes before and its not easy, I'm not going to do anything until it goes out but I would like to know before I go to swapping it. I would prefer to do away with it.

There are two mechanical pumps.
The first is a diaphragm lift pump that pumps the fuel from the tank and puts it in the filter housing. There is a return orifice that returns fuel to the tank from the filter housing to purge air. Pressure is regulated by the diaphragm.
The second pump is a piston pump that draws from the filter and sends it to the heads. There is a pressure regulator that returns excess fuel to the filter housing.
I don't know anyone who's done it, but I don't see why it couldn't be re plumbed with one pump and setup to return from the fuel pressure regulator directly back to the tank.

Jim is right. You can't add a E pump to the stock system cause the fuel filter housing won't take the 70 PSI. You can rework the whole fuel system with a pump, regulator and pre and post pump filters but its either all or nothing.

Sorry, I was less than specific. Yes, they are in the same housing.

I've been thinking about this for some time. Could you not use a low pressure electric lift pump to the filter then 70 PSI electric pump to the heads?
