Electric fuel pump placement?
I'm really leaning towards putting on a electric fuel pump (holley red), should I place it just in front of the tank selector on the frame rail with a in line filter in front of it? Any ideas or suggestions? thanks guys!

I already have the filter in, it's wired and the Holley's in the truck.
I've heard good things from guys on here about Genlightning's pump though. And I think it's cheaper. I'd check it out. The CHEAPEST you can get the red Holley for is about $100.
What ever you do DON'T run the electric pump through the factory lift pump. You can blow the diaphragm in the engine mounted pump and fill your crank case full of fuel.
Do as I say not as I do.
I have a cheapo Mr. Gasket electric pump on mine I use to prime the system and fill the filters, transfer fuel to my tool truck, etc. But it's a BAD idea!

Biggest advantage is that you don't have to crank the truck to purge air from the fuel system.
I'm wanting to go to an electric pump at some point.
Where can you get the Facet dura-lift? Looks like a good pump but I only found one place that seems to carry them (via a quick search on google)

interesting...so what happenes to the stock pump leave it in place and run lines directly to the fuel filter ? or is there a block off plate of some sort. And im assuming with the electric pump the ip pump sees a steady flow of fuel ?

I'm told you can use a big block ford blockoff plate there. That's what I plan to do.
The pump would probably sieze up with no fuel going through it, but I dunno.

I have the signal for the relay on my truck powered off of what was the power wire for the water in fuel sensor on the stock separator, it's powered in start/run only, not acc.
Location, like everyone else said, just to the engine side of the fuel selector is good, the lower you can get it the better for the pump it is, if you can get it completely below the bottom of the tank while still protected by the frame, that is where you want it.
Personally I don't like the Holley etc pumps with the dry, brush type motor, and run a Carter vane pump, which has a wet, permanent magnet motor, no brushes and it's fuel lubed. The things last forever...

Electric Pump
I put my electric pump inline between the mechanical lift pump and my Racor 2 micron fuelfilter/separater. I only use it to fill my filter, lines, etcc. The mechanical pump does the rest when the truck runs.
If the mechanical pump should fail, it is an easy hose switch to the electric if I should need it.
The mechanical pump pumps right thru the electric when it is not running.
No worries about blowing up the diaphram in the mechanical lift pump or filling the crack case with diesel this way. Worked like this for year.

i googled this pump to and it says that it has a min lift of 10 feet... wouldn't it have to high of a fuel pressure and blow stuff out? and it says it will do 125 liters per hour thats 33 gallons per hour... would that just mean that there would be more fuel recirculating or what? i think it would be kinda slick turn the key on and poof no more air pockets in your lines... it thats how it would work..correct me if im wrong
