How to install an Electric Vacuum Pump

Many high performance engines do not produce enough vacuum for reliable servo operation.
This neat little pump will maintain 18-22 inches of constant vacuum whatever your manifold pressure.
Inlet and solenoid hosetails are 12mm diameter and the exhaust is 14mm diameter.

Folks when the pumps mounted securely with the rubber mounts it's heaps quieter.Don't be put off with the test noise.I have done many thousands of K's in my car over 8 years and it has been faultless.worth every penny

[@LEGUESSCY]

That's great to know because damn it's loud in this video which is really off putting so thanku sir for that input 👍🏿

[@Whoisdissis]

Thanx for the help with this much needed addition to my new 383 Stroker in my 1981 Chevy Camaro Z-28 ..

I went through two of those style switches and neither worked. Once they reached vacuum they would come off and on but wouldn't stay off. I tested them the same way you did in this video. Had everything wired and grounded properly. Junk switches. I went with one with a built in relay from Superior transmission.

[@lowerbuncombecoachworks3384]

I'm having this same issue right now and I figured it was likely the switch. I have another switch coming so hopefully that solves the problem

[@perjian1697]

That takes really long to reach vacuum with just a short rubber hose attached. Hardly seems like it would be sufficient for use in a vehicle.

[@louiechidwick6034]

As there's no connection from the ignition switch to the relay, then this pump can start up continuously if there's a slight leak in the system and flatten the battery over a period of time. Imo, I would install a dashboard mounted switch at the very least to isolate the pump when it's not needed.

[@williamlopez4934]

I had problems with this switch. So I just install a timer cycle relay. What u can do to is replace the relay with a delay relay. Think they run about 30$

Haw to install vacuum pipes for Toyota Noah 1az D4

[@creepycrawler4690]

I've never heard of the relay legs numbered 12345..they are numbered 30-85-86-87 How are people supposed to know is what to wire it properly.

[@CarBuilderSolutions]

It's a timer relay. Full wiring instructions are included with the pump and can also be found in our online listing.

[@mandapalque]

@@CarBuilderSolutions What is the part number for the pump? Thanks.

[@phredpun4225]

Some relays are marked this way. 1=85, 2=86, 3=30. 4=87A (current flow through contacts with relay coil off) and 5=87 (current flow through contacts with relay coil on).

[@cathychow3245]

@@phredpun4225 Thanks. I wondered that as well.

[@TheExBx]

While I realize this video is 4 years old do you know the part # to the vacuum switch? It appears these days acquiring a good switch is borderline impossible. Thank you for the video!

[@DavidRivera-dw8uw]

It is compatible in a econoline E350 7.3 diesel?

[@kermitefrog64]

Is there a link for this vacuum pump? Could this provide enough vacuum to replace the mechanical vacuum pump on the Mercedes W123 diesel engines?

[@hughbunyea9906]

Would u or somebody be willing to help me get one hooked up on a 2015 Ford Escape Titanium. The factory pump is actually the cam and it broke off. Either way the vehicle still runs fine but the brakes are hard.

[@josephcampbell1146]

Hi I'm interested in your product where can I buy one in Pretoria this

[@MrChevy2188]

Excellent video

[@ryanduffin847]

Is there a link to this item please?

[@markcarbonaro6524]

Which brand of vacuum pump is this?

[@Cobra427Veight]

Hi, it seems like a lot of people have issues with their pump continually pulsing ,me included , it was great that you wrote "timer relay" in one of your answers , can you explain to me the part number or delay times , like if you hold you finger on the end of that pipe i:e no leak will the pump turn back on after a certain amount of time that is set on the delay ????? More info Please , Cheers .

[@ElectroSyncro]

Hey. I had this problem too. It turns out the pump on the exit side doesn’t hold air on my pump. I added a one way valve before pump. Works great. Hope this helps 2 years later.

[@deanberger9597]

I have a strange problem with my 69 coronet, I'm running 2 electric fans from my EZ-EFI and a vacuum pump. When city cruising and I get up to temp I lose the fans and vac pump. when system cools after sitting everything works again. also when driving on highway everything stays working. Do you have any ideas what could be going on? I'm stumped.

[@darrentylor5473]

Gnd to temp switch Temp switch out to 85 86 to positive jump to 30 87 to fan positive Fan negative to gnd

[@darrentylor5473]

The vacuum pump should have its own circuit and be contolled by a relay and pressure switch.

[@neilhannant5994]

Can this be mounted vertical

[@CarBuilderSolutions]

Yes it can, but you might have to choose some different rubber mounts as they are not designed to be hung.

[@feral4mr2]

Hi, can these vacuum pumps be ran continuous? Thanks.

[@CarBuilderSolutions]

Hi. They are designed to cut out when maximum vacuum is achieved. Continuous running may reduce the life of the pump.

[@feral4mr2]

@@CarBuilderSolutions No worries. Thank you for the rally. Thinking of using it for a crankcase vacuum setup.

[@creepycrawler4690]

I take it you can't figure it out either. Thanks anyway!
