Not exactly what you want but this info might help. Here is an old post of mine:
These directions are for older kits that came with twin AC pumps like mine did. It was bought in 1995 and included the hobbs switch and all hardware. If yours is a later model and has (2) Walbro 242 or 307 pumps then you won't need to change much of anything, maybe the wiring only, but I think that is the same too.
On mine one pump was failing so I went all out and did the (2) Walbro 340 pumps. I had to make a new bracket that would hold the pumps on the bottom since the bottom of the Walbro pumps are larger and not offset like the AC pumps. I used the original ATR lower bracket to patern a new one from a piece of stainless bracket material I had around the shop.
You will need a 3/4" hole saw for the holes that the pump inlets fit thru. The top billet coupler worked great with the new pumps after one simple modification. You will need to use a snap ring pliers to remove the snap rings securing the washers inside the coupler, get a drill bit slightly larger than the Walbro pump outlets and make the holes in the washers large enough for them to fit thru.
This is easier than it sounds, trust me. Don't ya just love when someone
says "trust me"??
Anyways, they were a tight fit going into the tank but it worked well. One
other thing I had to do was take a ball peen hammer and gently enlarge the
tank opening where the 2 pumps are lowered into the tank. I dented the
opening just enough to make the pumps fit down thru and not enough to
disturb the o-ring seal area. You only need to slightly enlarge two spots directly across from each other in the position that the pumps go down thru. I used an insulating boot over one pump for noise reduction, and I had to use some WD-40 on it to get the rubber to pass thru the opening. They are working
great and I turn the #2 pump on at around 20-21# of boost otherwise the
motor goes way rich. Those pumps really push the fuel!
Good luck and e-mail if you have more questions.
