Question to throw out there for all you guys with other than stock fuel delivery systems in your 7.3 Power Strokes. I have had one for years now and have run an Automotive 1000 pump, model 11101. Last October I changed out the pump for a new one, as the old was starting to leak (my fault for that, but that's another story). This month the new pump quit pumping, making noise, motor turning, but no fuel. I contacted Automotive tech department and explained this as they do have a one year warranty (if it meets their conditions). Was asked, of course, what my set up was. Told him it was in a Ford Power Stroke, and explained the plumbing set up as shown in the first diagram. I do have a sump on the bottom of my tank for fuel supply. Running 1/2" fuel line to Y just before back of heads. Used the original supply line as a return line. Regulator set to 65 psi. Vehicle details in signature line.

The first thing he told me is they don't recommend this pump for diesel applications as diesel conducts electricity better than gasoline. They now recommend model 11183 which is brushless. Also the way I have it plumbed creates a back surge in the fuel system that puts stress on the impeller (my word) motor shaft hole. It's a D hole and can spin it out. He said guys are now using a Holley manifold and getting more power and it's easier on the pump. He explained the plumbing to me and the below diagram is what I think he means. I sent both diagrams to him, but haven't gotten confirmation if the one below is what he meant.

So to the question. Does this plumbing look like it would work? The first concern I have is getting air out of the system during filter changes. High point above heads to blead air off? Am also looking at Irate Diesel\s Fuelab Prodigy Fuel pump as an alternative in my original plumbing.

If there is another way to plumb, I'd love to hear about it. Thanks.

 

The bottom one doesn't look like it would work to me. Like you stated, nowhere to bleed air. As well as a single line from the regulator to the engine, no place for excess fuel after that point either.

 

I totally dont see how the original routing would be wrong. Literally thousands of vehicles are plumbed in that manner. The only thing that could do any good for spikes imo would be an accumulator of some kind. I say they are full of crap. Do a fuel lab pump . Aeromotive I have heard having lots of issues with pumps.

 

Your original routing looks good to me, thousands of E fuel trucks running around like that with no reported issues. I would try the Fuelab pump before trying the reinvent the wheel.
