Does anyone have info on the style/type of fuel pump furnished with the Procharger M-1 MPI kits originally?

I have been informed by a local builder that Procharger had numerous failures of their fuel pumps and this caused substantial engine failures.

I just want to make sure I'm not running one of these fuel pumps.

My fuel pump is a 8" long aluminum pump, flow through design.

I'm not sure if it's the same setup you are talking about, but Aeromotive had a batch of pumps out that flaked off some phenolic stuff from the inside and sent it on to the injectors, causing lean cylinders and engine failures...

Seems the cause was due to an overly restricted fuel feed line TO the pumps, which caused the pumps to cavitate and overheat.

I seem to remember that Aeromotive would open and replace the pieces that would fail with updated pieces for a buck fifty or so (i believe they would charge the same for a failed pump or a pump that had not yet failed).

The proper fuel routing would eliminate the cause of the trouble. A 100 micron screen filter BEFORE the pump is recommended. This size keeps stuff big enough to harm the pump out of it but is not too restrictive for it. THEN a high-flow waterseparator/filter after the pump BEFORE the regulator (carb) or fuel rail (injected)...

A carb motor should route the overflow fuel from the regulator back to the TANK, preferably thru a cooler first (not recirc to a tee in front of the pump).

I believe you can call Aeromotive with your pump S/N and they can tell you if it is a pre-fix or fixed pump.

Try this link. Some good information in my opinion on how fuel system needs to be set up. It is a little long but check it out.You can do a search on aeromotive pumps also. That is probably what you have but you need to check and make sure.

aeromotive has had some problems with the reformulated gas, the alcohal would break apart the adhesive. if your pump was manufactured before june 02 they will rebuild it with new parts that will hold up with our great gas,fuel return lines should be routed back to the tank on carb & mpi engines when it is possible

Also,
Before Aeromotive PC used to use a pump called SX. I burned up 2 of them.
The Aeromotive seems to be working fine.

I appreciate the input.

Just want to make sure everything is right when I install my new engine. The last builder wasn't too good. The engine had the wrong rear seal, severely worn valve guides, loose wrist pins etc... A really sloppy rebuild. This time its done right and I sure don't need a faulty fuel pump ruining my good time!!!

If you use the Aero. use #10 lines to and from and return from the reg back to the tank. That will keep enough fuel running through the pump to keep it cool.

My pump doesn't resemble anything on the Aeromotive site???

I'm trying to locate a picture of it to post.

I received the updated "Red" fuel regulator from Procharger. How would I plumb this regulator as the original regulator bolted directly to my fuel cooler. Does anyone have a diagram or picture of the installtion with the Red Regulator? Is there a blockoff plate for the cooler?

No, thats not it. Here's a picture of my engine, the pump is the aluminum cylinder that I circled. Not a great shot, I'll post a good picture as soon as I can.
