Mechanical pump to electric...can it be done?

The fuel tank selector valve on the left frame rail is a solenoid that switches between the front or rear tank, the switch on the dash selects the fuel sending unit and energizes the selector valve from what tank to pull from 9 times out of ten the selector valve on the frame goes bad and thats what gives you the trouble, the plunger might move in but the connections in the valve get corroded and that is the major problem, I have seen those valves on e-bay and got my 86 with the diesel working by replacing it.

There are...
The main reason is because my first '86 F250 I bought had them in it. I liked turning the key and hearing the hum. I noticed that it seemed to start a lot easier than my mechanical pump one. Also, the mechanical pump relies on your bowl staying full to help it start. And in MN winters, when I need that truck to start...I really don't want to put a lot of strain on the starter and battery to pray it'll get enough fuel to kick over. Personally, i'd rather have something deliver fuel much faster than relying on either a full bowl, or the cranking of the engine to get the fuel moving.
Just seems a little easier to me ya know? Mechanical pumps may be reliable, but they can go out, and if I can do a smaller pump near the firewall for example and run the fuel to the carb that way...then I think that would be easier.
Fuel runs freely via gravity to the valve (don't ask me how I know
). So I would imagine an electric pump on the engine side of the valve would work out.

I was meaning just to get things going. Fill the bowl, cut it off, mechanical takes over as engine starts.
That is a glimpse into the mind of a man who thinks obsessively about his truck all day while he should be focused on working lol.

Nope, haven't checked that yet. I do know that the filler necks are both looking a little chuggy, so those will need to be replaced here eventually. I'll have to check those lines when I next get a chance. That might be part of the problem too.
