Been running one for alot of years, it didn't help the performance of the engine any but it sure took care of the nagging leaks I had at the rear main seal and the valve covers. One side note, I run methanol and the pump really helped to avoid milking the oil if I run the pump while I am warming up the motor.




Yep I ran one on my dragster with injection and I since I just put the injection on the Dart, I decide to put the pump on it too.

You can wire it up with a relay to come on with the ignition switch, Or just toggle switch it on and off.

With Alky I like it coming on with the switch so you don't forget it.

Gas it wouldn't be as big of a deal.

One last question and I will stop. Star Machine's tank allows for the pump to go second from the tank to eliminate the chance of issue with oil junk up and pieces getting into the pump. Will the electric pump work for this or will it reduce the vacuum? thanks chuck

Mount the AC Delco unit with the rubber boot up and take the filter out and you should be fine..

I would expect you to be rigging up a shop vac in the passenger seat and your little generator in the trunk - your going all high-tech now.....

I can do that, I think . What about the relief valve and one or both valve covers? Also, what tank do you use? Thanks Chuck





It doesn't pull enough vacuum for a relief valve. I never used one.
I didn't even use a puke tank.

I had this breather in Valve Cover. Moroso # 68788

I am very interested in this system, having to fight misc oil seepages. Could someone post some pictures & more detail on their cars with the vac pump from AC/Delco & how they are using it?
Thanks Steve

Here is how I do it on alky.

I am concerned about moisture so I come out of each valve cover at the front, go into a breather tank that catches the moisture so I can drain it, then come out of it to the vacuum pump.

I don't think its a good idea to suck any oil and water through these pumps so that's why I put a catch can between the engine and pump.

Will post a pic of my setup after while.

Finishing it up right now.

Ok here is how I rigged it up with my alky injection I just put on this past week.

First pic shows out of the front of the valve covers and don't forget to make sure they are baffled or it will suck oil when the engine is running.



Second pic is the breather setup I use to catch the moisture from the alky. I mounted the pump under the fender up front to save on space under the hood. The breather tube runs down through the hole where the battery tray was originally. As you can see the clear tubing is completely fogged up with moisture and water droplets with it running so its definatley pulling it out. Better off there then in the pan!



Last pic is the pump under the fender.

That red hose is the air outlet for the pump.

I just run it down along the frame to the lower control arm area.

If you are on gas or using it on the street it might not be a big deal where you run it to but I was concerned if it blew some moisture out on alky, where I ran it.

That tank is a moroso breather tank that I chopped up and modified into a catch can.

If you run on gas and had your valve covers baffled good you and didn't suck any oil into the pump you could go from the valve covers through the pump and put a breather tank on the outlet of the pump.

Moroso 85470 would work for that.

Thanks for the pictures & descriptions, they clear up all confusion. Our car runs on 111 race fuel so I hope not to see very much if any moisture, I'm just tired of the continous oil seepage. Thanks again Steve

It should fix that.

Had a friend who had a 8 second Beretta and it had some oil seeps. He put on on it and it fixed it right up.

I had an annoying pan gasket leak that would leak oil on the trailer floor between races. I had the header evac's on it the last 2 years.

Ran the car with the electric pump on yesterday and checked this morning and the floor is dry as a bone!



Also, I came back from a pass yesterday and noticed that the dipstick was blown out, and oil had leaked from the valve cover gasket on the pass side.

A further investigation found that the fuse holder that powers the vac pump lost contact and it wasn't running on that pass so yea, these things do make a difference!
