So I have a 93 F250 7.3 IDI 4x4 ZF5 which I purchased for running WMO. W85 and WATF specifically. As I'm preparing my truck I am making sure it is operating fine and tune up so that it's in excellent running condition first. New GPs, injectors, eventually oil cooler, valve gaskets, 2 micron Wix fuel filter, fuel lines, fuel heater, cleaned fuel tanks, oil change, coolant change,and cpl oil leak. I run it in Texas but plan on a winter trips up far north for a while. What I am curious about is figuring out my fuel pump set up. I am going to get rid of the mechanical and replace it with an electric pump for reliability, easier starting, and all the benefits. Since WMO is thicker than pump diesel I am thinking that the Facet 40222 doesn't have enough grunt to pull it. Do y'all facet users think think it's capable enough? I was told a push pump is better for WMO. Especially in colder conditions when it's a thicker consistency until the fuel heater is getting it's job done. With these things in mind, I am figuring a dual fuel pump system would work best if a pull pump isn't feasible. Is this a good idea? A pull pump in the engine bay, and a push pump near the tank. My question is deciding on the pumps. I've been told a Holley blue push pump is very good, 88+ gph 9-14 psi for gasoline. I know someone running it on there IDI already in Texas and will get it if I need a push pump. For the pull pump, I recon a Facet 40222 would be fine with the help from the Holley blue sending fuel up. If I can get just a pull pump though, I was thinking perhaps the Facet Dura-lift 40290 which is rated at 9-15 psi @ 50 gph. I just know that I need ~7 psi and at least 30-35+ gph for the IDI so I don't stall out. I figure two pumps is better than one, and if one fails I can limp to a destination. I do want reliability and would rather have one pump with a spare, or two pumps that can accomplish on their own. After the pump (s) I will have a psi guage or regulator to prevent blowing the IP gaskets out. I am wanting to go with the higher psi and gph pump as I am expecting to loose a little of both because of the consistency of WMO going through the lines, and the 2 micron fuel filter.

Pumps:
Pull
Facet Dura-lift 40222: @ 9-11.5 psi; @ 33 gph.

Facet Dura-lift 40290: @ 12-15 psi; @ 50 gph; says average use @ 20 gph @ 8 psi.

Push
Holley Blue: @ 14 psi max @ 110 gph Max.

Summary of questions:
Is the Holley Blue able to push on its own?

Is the Facet 40222 able to pull on its own?

Can the 40290 pull on its own?

Instead of the 40222 shoud I get the 40290 which has 50 gph vs 33 gph?

Should WMO have a push or pull pump, or both?

Should I run dual pumps?
​​​​​​
What's the general specs desired for electrical pumps, i.e. check valve, psi, gph etc.?
​​​​​​
Amy other WMO advice or something I'm overlooking?
​​​​​​Thanks,
Looking forward to it.
