Here is what I did:
I have Fitech as well. I run from the pump, straight to the throttle body, and instead of using the built in return, I have it plugged, and I return from another inlet on the throttle body. The fuel goes through the Ftech, out of the inlet on the back, into an Aeromotive regulator, and then returns to the tank. The gauge is setup on the regulator and I have it set to 58 psi since I'm using the 1200PA system. I tried running to the regulator first and then out to the Fitech but I had low pressure issues. It has to be ran through the Fitech first and then returned.

That would eliminate any potential issues with the internal regulator, and a great idea. What type of low PSI issues were you seeing?

Guy I was helping spent hours and hours on the phone with support, they went over the throttle body twice and sent it back. He lost patience and just went back to the carb. Tech just kept pointing to his fuel system, but it appeared to be all in order. But tech did say that you can't use the pump output for walbro and some other in tank pumps. It is in the docs.

Mine would not go above 40 psi, and it needs 58 psi. I was told to try this fuel routing from a member in the Fitech Owners page on facebook. It makes sure to get full flow to the FiTech and bypasses the built in junk regulator all together. I'm running a 380 lph pump so I have it wired in with a relay and set to 100% pwm. Using -8AN Feed line and -6AN return, push lock style hoses. I have pre and post cleanable filters. I wanted a fuel system that will handle more power later on.

Very good, I'm liking the approach. Yes, bypass internal, and with the relay, you basically bypass the internal PWM too. That could pulse and even have voltage drop below 12 and still apply full power to the pump. Makes total sense.

Good Deal Squid. You may need to check your dead head pressure, just to verify the pump will indeed make enough pressure to overcome the regulator. Just for a short time, like 5 seconds, and it should hold that pressure after you take power away, maybe at least a minute, as long as you dont lose it right after you take power away. If you do lose pressure immediately, its going somewhere??? hose split? check valve stuck open? the splashing in the tank is what worries me.

I use the Tanks Inc. tank and their PA-6 pump plumbed with 1/2" line to the FITech with 3/8" return, no additional any thing and mine runs fine. The pump itself puts out 90lbs. to the throttle body as measured with my Auto Meter gauge. Pressure on the return side is 58 lbs. exactly. No issues even when I dial down PWM.

Ted, I installed the pump.

I put together some fuel line so I could check pump output to a gas can and half split between pump and regulator. Wife wanted pizza for dinner, so I ran out of time before work. We'll see how it goes in the morning. I might end up going to bed smelling like a Chevron station.

I'm guessing it should be obvious if the pump is working if it is wired with straight 12v, and discharging with no head into a 5 gallon gas can. It should be a pretty strong blast of fuel. If the pump is good, then I return the tanks inc regulator. Shame... it seemed like a nice piece for the money. I would then explore other plumbing options. I really liked the idea of a single fuel supply line running to the engine bay, but it has to be functional.

I'm hoping I didn't mess up the install and have the pump discharge tube come loose, or the suction screen somehow clog the pump inlet. Worst case I drop the tank again.

The pump outlet, and the inlet pipe were not "inline" and over stressed the nipple. I would work on lining everything up as best you can before putting the line on. That plastic line is short and rigid, not much you can do about it. If it doesnt shake, it breaks. Good Luck.
