Hey guys. Questions for any of you running stack injection systems with the front mount mechanical fuel pumps. I'm picking up a MOON front timing cover that has the removable plate at the cam drive. I have a friend with a Hilborn PG150A pump. Anyone with info on that pump? GPM, special info about it or using it? I want to use it to fuel my EFI system if it can produce enough pressure and flow. I'll use a return/bypass regulater too. Are you guys using a front mount gas tank to feed it or are you pulling all the way from a rear tank? Any and all info is welcome. Thanks guys. mark L

150 would be the pump's flow rating, Mark. Not sure about the pressure, but a quick call to Hilborn with the part # and serial # off the pump (if it's on there) should supply you with all the information. Also, if you're planning on having the car on the street with EFI, might want to consider a vacuum referenced pressure regulator with the return port. The pump will pull fuel from a rear tank, but a good one way check valve would be a good addition to the system so all the fuel doesn't drain back to the tank everytime you shut the engine off.... Never have had much luck with the engine driven pumps on the street, tried them a couple differet times and always wound up going to an electric pump mounted by the tank.

Thanks guys for all your help so far. Probably right that the mechanical pump is not the answer. I'll probably go to an Aeromotive A1000 electric. That's what I had on the TA. But it would have been cool to have the Hilborn pump up front doing it's thing. Mark L

Johnny, 80 A??? Can you tell me more. Not sure what you mean by a 80 a. I'm maybe running EFI and going to turbocharge it so I have to make sure the pump I chose flows enough lbs at a higher pressure. My Trans Am made 1065 HP but I had an 830 Holley Blow thru carb. So the pressure only had to be about 20 lbs at full boost (15 psi). I'm going for even more HP on this engine and, although I do have a 750 blow thru to use, I also have much stuff for the EFI requiring at least 65 to 70 psi. And the flow??? We'll see as the build progresses. Mark l

Great tech guy

Call Andy Star at Hilborn, he was fantastic to deal with when we were doing the Carabine EFI setup in the bird.

Hey Mark, the 80a pump has been around forever. Mine is actually a crower, most were hilborn. I did have it flowed and can post the numbers if it helps. I dont know them off hand but can get my tag and post. From what Ive been told, it was the most used sized pump back in the day and STILL are very available. The pump I have is vintage 70s stuff,never rebuilt (I know of) and works very well for my applaction. Ill get the tag and post this week,or pm me with your # and I will call with them.....

Mallory makes a high pressure & flow electric fuel pump that you may be able to use.

This would allow you to use a srock water pump.

The 150a-1 pumps are used for blown alcahol motors & maybe to lage for the stack injection

You could probably use it by increasing the flow back to the tank.

May need a small surge tank up front & pump the fuel from the tank in the back to the surg tank.

I have 3 blown & injected motros running omn Alcahol with a blower & when you get them ironed out WOW nothing like a blown .injected motor.

Hi Kevin:
Did your son close the deal on the F troop willys?
I talked with Steve @ the March meet.
Stay in touch.

80a pump I believe is used for a bb stack injection & there is a smaller pump for the small block injection.

I've been looking into this Hilborn pump. I sent a contact to Hilborn and Andy replied. Nice guy with great info. First problem is Hilborn dose not make a spud for a Pontiac. He said yo cna modify a chevy spud so I have ot look into that. The next is Moon. I have a Moon front cover but it comes with a blank (unmachined for a pump) front access cover. I contacted Moon about buying just the plate but am still waiting for a reply. I don't want to buy a whole new timing cover just to get the plate. And as mentioned. I'd probably need a front tank, fed by a normal electric pump and feed into the Hilborn pump. I have a real problem with a real front mounted (anywhere forward of the firewall) mounted fuel tank and a frontal collision. I could probably have a nice 2 gallon tank built to mount up front but even that would be too much of a fire hazard. And in reality, by the time I've spent money to build all of this stuff, have a gas bomb sitting up front, and plumb and mount everything, I'll be way ahead with just buying a good electric high pressure modern pump. I really like the idea of that Moon front cover and the hilborn pump. Now for something a little differnt ( a flash of an idea exploding in my head, heh)(or was that an aneurism??) since I may be able get the pump for free, gut it and seal it and run the elecric fuel pump thru the Hilboorn. Put in on but not run off the motor. Just a shell for looks. Run the electric thru it to the regulator after the Hilborn. MMMM. Interesting. Have to see if the owner would be allow me to modify it for non use.? Kind of like that idea. Mark L
