The real restrictions are the two filters inside the mixing chamber. You apparently didn't open it up and look inside. They're very fine mesh. The strainer on the foot will only keep put the big chunks.

No idea, I generally think INSIDE the box. Not likely to lose power to it since I solder and cover all my wires, but yes, the pump certainly could fail, especially since it's a pretty cheap pump.

Yeah, I experienced that problem . . . when I pulled the tank, the original pickup foot had broken off and was swimming in the tank. So I bought a new one from my local Ford dealer for $40. Friendly people there, first time I have been in a Ford dealer in a long time! Was actually surprised they had it in stock.

You're right, I didnt open it up . . . I threw it in the trash.

Personal experience on my 2001 before the hutch/helper pump but with FRx already installed my fuel pressure fluxuated between about 52-60ish psi. After the mod with the extra pump my fuel pressure held a steady 62 psi. The throttle was more responsive and the truck had more pep. No programmers/tunes/anything on the truck. Only mods were afe intake, frx, and #8 injector swapped to standard ad.
More recently did same mod on my brothers 02 with several mods and ts/gearhead tune. Didn't check fuel pressure before or after but truck has more pep, better response, and slightly better fuel mileage.
For no more than the pump costs I feel it is definitely worth it! But that's my opinion and worth exactly what you paid for it...

I still think the helper pump is a good idea, but as Short Stuff pointed out, it would be a good idea to know what the helper pump does if it fails or loses power - in other words, check to see if fuel still flows through it.

The day I wrote my response to his question in post 17 above, I lost power in the truck for about 15 seconds - it went to idle and would not accelerate at all, then after about 15 seconds it came back to life. This was a problem I have never experienced before, and fortunately I was not in traffic like I usually am. It was also not like a CPS failure where the engine completely shuts down for maybe only a second or two; I dont know what caused it, but it certainly could have been a hiccup from my too-cheap pump.

So if you're going to do a helper pump, you should probably get a better quality one, like a Carter P4070, which is what I plan to do.

Gator, what brand/model did you and your brother use?

I use the carter p4070 or equivalent. I also have extra hose left at the pump so if for some reason I need to bypass it in a pinch I can as well as leaving the factory line in place so that if absolutely necessary can go back to stock configuration easily. I have never had to do either. I have all the parts handy to do this to my 2000 as well just waiting on time to do it...
Seeing as how the carter is a rotory pump as long as the motor doesn't lock up then the factory pump should be able to pull fuel. I also believe that the rotory has a bypass valve in it. I have used this style pump in other applications and had them fail and the injection pump continue to pull fuel and keep the motor running without issue.
