[@dennishnks]

What size fuse are you using on the constant true ignition and would you recommend this for all the holleys Red,blue and black. Oh by the way I did get my relay and the pigtail for it thanks. I really liked how specific your diagram is.

[@AnthonyJ350]

You'll have to review the instructions, it will give the recommended amperage rating. It's typically not very high. Make sure you ground the pump well.

[@shaolinmonk8620]

Great video! So this relay wiring should eliminate the oil pressure safety switch?

[@AnthonyJ350]

It can or you can use it in conjunction.

[@shaolinmonk8620]

@@AnthonyJ350 as I understand it, the relay only sends the signal when you turn the switch on (momentarily), the fuel pump needs the signal at all times. So how to?

@Spun Tomato What didn't you like?

[@lt.schlechtnacht9414]

Great video! straight to the point. My only question is, what do you do if there is no spot to get a switched ignition from? for example on my 85 C-20 the only wire that I could find that is a switched ignition is the distributor wire. Could you make a terminal block that the distributor wire feeds both the relay and the distributor?

[@AnthonyJ350]

There's a switched ignition at the ignition switch harness.

[@J71CHEVY]

Thanks for that sir! Just want to make sure... 87-To Battery(Fused) 86-Ground 85-Ignition 30-To Fuel Pump(or device being used). 10 Gauge wire sufficient? Thanks in advance for the reply!

[@AnthonyJ350]

Yup and 10 gauge is more than enough. So sorry for the late reply, I just saw this one.

I am installing a red holley electric fuel pump. My question is where to get the relay and the pigtail for it

[@AnthonyJ350]

An installation bay should be able to sell you the parts.

[@patrickcurram9763]

Just use the one in the truck car.

[@eriku571]

Am l right in thinking that you only have the power wire going to the fuel pump because the pump is grounded to the frame?

[@AnthonyJ350]

Correct

[@Rowed1911]

How do you bypass the return fuel line because my truck has a main line, vape line and the thinnest one is the return. Also, does the fuel pump have be closer to the tank or the engine?

[@AnthonyJ350]

I maintained it. Used a fuel pressure regulator with a return.

[@707SonomaComa]

Awesome video, great explanation. I would like to install that on a 1970 Chevy C-20. If I get constant power from the junction block from the positive side of the battery, then create a ground connection, where would I get the power from the ignition? Somewhere on the fuse box? That is what I am just not sure about. Where can I get power when the key is turned to the on position?

[@AnthonyJ350]

You can find an ignition wire typically at the fuse distribution. Just make sure to put a fuse inline.

[@707SonomaComa]

Thanks for the info.

Im having an issue where my new vane pump wont stop pumping and it floods my carb, it pressurizes but won't stop like my old diaphragm pump I had, what is the reason behind this? is there a way to wire in its own fuel pressure switch? im new to wiring my own truck so im still learning so please help if you can. - ian

No not enough amperage on that circuit. Needs a dedicated true ignition circuit for safety

[@elcuh7939]

Hopefully you still reply I was wondering I have a 79 camaro I bought it recently and it didn’t have the mechanical fuel pump so I bought an electric one but I am so confused on how to wire it since it doesn’t have an oil pressure cuttoff switch and I don’t know if it’s necessary to buy it or how to wire it. I was wondering if I could wire it to the neutral safety switch? Can you please give me an info on how to do it safely I was searching all over the internet and this is the only video I have sort of understood.

[@AnthonyJ350]

It is best if you can wire in the oil pressure switch. It will go on PIN 85 and provide a negative trigger. You can send me the diagram of the product you're looking at.

I have yet to order the switch I found a diagram on Jegs here it is www.jegs.com/installationinstructions/500/555/555-11200.pdf Do you have a video on installing an oil pressures switch?

Hiya mate, please help if possible. Ok, I'll try keep it short for now. I bought a Suzuki ignis sport for rally / fun. With original tank / pump it started on the button 100% ...I removed the large under body tank / pump. I installed a 15ltr tank in the back. Bought an inline universal high pressure fuel pump. Cost £60 nearly from a motorsport shop. The first one I thought was faulty, sent it back, got a replacement after some haggling. The key point is that I have it wired off the original fuel pump wiring. Ignition = prime ..turn key. Car starts no problem .. BUT! As with the first one it started on install / test. But almost sounds like it's struggling and starts to either starve or I just felt it best to turn it off. So with the first pump and now this second pump. Both the exact same ...the next morning I try to start the car and its not starting. Pumps making noises like its priming but won't pump the fuel. When the motorsport shop took back the first pump it was tested and it pumped fine for them for 30 mins but said I just sounded a little noisy. But this is both pumps failing to start the next day! There is fuel, flowing.. as in if I disconnected the inlet on the pump @ 12mm it's flowing fuel into a bottle. After watching your video I believe it's got to be my wiring or something ..You mentioned the pump might require a different wiring / current or something ...Is it possible I'm coming to the correct conclusion? Why if instead they both worked fine but now it won't pump fuel. I'm pulling my hair out trying to figure out what I need to do. Battery I fully charged, zytech 12mm in out filter before the pump + plenty of fuel.. what could I be missing or not doing correct? Please help, any advice is greatly appreciated!! :)

[@AnthonyJ350]

I would install a fuel pressure gauge, that will help you diagnose the problem.

[@blizteredthumbs7911]

@@AnthonyJ350 Hiya, cheers for the reply. Would this not only help if there is fuel pressure to gauge in the first place? ...this is my issue. When I first install pump as new out of the box it works no problem. Or seems to. But try it the next day and it won't ignite. When I brought the first pump back they tested it. Not in front of me though. They advised it pumped fuel for 30 mins no problem but was just a bit noisy. So I can only gather from this that the pump isn't getting the power it desires? I guess a test would be to put a volt sensor on the + - on the pump while someone turns the key? ...another point I was concerned about was the original pipe work was fuel sender line, a breather pipe and what we assumed was a return line but I could not get fuel to come out of the return line. Is this possibily an issue ...if the fuel gets sent continually but is unable to return then it would stress the pump out? Maybe causing this issue? But what gets me is the 'test' these guys did with the first pump they advised it pumped fine so I am just pulling my hair out trying to figure out am I completely stupid or am I just missing something simple? I'm a technical kinda person and I don't do anything which I know could potentially damage things so I like to ask questions before going and doing something you'll regret later kinda thing. I know this kinda thing is difficult over a keyboard but I'm just hoping someone somewhere might have the answers :) thanks in advance again Anthony !

That was is correct and virtually the same if you saw how the internals of a relay work. Just follow their diagram and make sure to put a fuse inline where ever you get power from.

[@simonilett998]

Your method obviously worked, but it's not a good idea to be teaching your students this way.👈 If the relay has a freewheeling/reverse polarity diode fitted, you will blow the diode.👈 Sandard practice is actually the opposite of what you showed.👈 For a traditional power side switched circuit: Pin 30 should be the fused power (+) supplying the relay. Pin 87 should be the switched output power (+) to the load/accessory being powered. Pin 85 should be the negative (-) terminal of the relay coil. Pin 86 should be the positive (+) terminal of the relay coil. 👍

[@AnthonyJ350]

You're saying the diode is fitted between pin 87 and 30? Or 85 and 86?

[@simonilett998]

@@AnthonyJ350 A diode in reverse polarity is sometimes fitted on some relays between terminal 85 + 86, commonly used if the relay is controlled by a transistor or some sort of electronic circuit, ECM etc. If you get the polarity of these connections incorrect, the diode will effectively be dead shorted and conduct, causing the diode to burn up. Look up quenching diode, freewheeling diode, snubber diode, flyback diode etc👍

[@AnthonyJ350]

@@simonilett998 Do you know what brand of relay has the internal diode? Because Tyco and Bosch don't. Also the other problem in the industry is every manual sometime 85 is ground other times it's the positive trigger. And no manual even discusses the diode.
