Holley Red fuel pump=NOISY?

Do you have it rubber mounted? If not try it.

 

Holley pumps are notoriously noisy!

I ran a Carter electric and you could hear it, but it WAS in the trunk of a Fleetline with no backseat! It wasn't unpleasantly loud and it worked GREAT. Much quieter than Holley electrics I've run in the past (and more reliable too!).

 

I had a red holly in a 34 ford, and it was really NOISY!! Then it started to over heat and it kept quitting. (not good when you are doing 80 mph in the left lane and it stops working. Switched to a Carter and it seems fine.

 

i think you just need louder exhaust.

 

I agree with The Hackster- I have run the carter electric on my car for 7 years now-you can barely hear it in the cutlass.

I have used these pumps on everything from mild to wild, and they don't quit.

I found out about them on accident-I was sitting at our local speed shop when a local racer came in and tossed one on the counter and "demanded a refund"
seems it had only lasted for 13 years.
the one he had before it had lasted a solid 15.

after that, I am a beleiver. not to mention they are about 75 bucks-and the mounting bracket,hardware AND wiring pigtail are included.

 

Holley reds and blues are fuckin noisy as shit even when rubber mounted. I had 2 blues in the bracket car with open headers and you could hear em while rollin up to the staging lanes. Look at it this way, at least you know it's workin

 

It must be the Street Racer in me But I love the sound of a noisy as hell Holley pump. Looks like it will be a Holley and not a Carter for the Hudson

 

Below the level of the tank is always best. Most electric pumps do very well at "pushing" the fuel vs "pulling" it. Below the tank level keeps it primed. And closer to the tank is the prefered method. I have indeed seen other types of mounting work. High gear at WFO should tell the tale if it's weak by design. Perhaps a net search can tell a little more in detail. Look for drag race fuel systems or sumthin similar and the theory of all this will be in there like lbs of fuel per hour per horsepower and such. Even if it's not a fire breather things like vapor lock and high speed lean out really suck.

 

It is better to locate an electric pump close to the tank. The reason is electric pumps dont pull vary well, but are excalent pushers.Your pump may be louder then normal becose of the added strain of trying to pull the fuel to the front of the car.

 

it is recomended to be below the tank and as close to it. If it has the pickup tube in the top mounting the pump below the tank will cause a siphon to keep it primed and not work as hard.

 

Hey Jeff,
Fast Elvis and I were talkin about you at Billetproof today. I guess you would have been there if yer pump wasn't so noisy Seriously you missed a good show. Hope you can make it some year. All of the advice you got here is right on. Get a Carter (maybe a P4070) from Jegs and enjoy the engine sounds and not the fuel pump noise.

Pumps run hot because of insufficient voltage.
And burn up in a short time.

Measure the voltage at the pump.
It should be within .2 volts of voltage read at the battery.

If you have to, get a constant duty relay.
Place it close to the pump and supply the relay with 10 gage wire.
You can run 14 gage to the pump from the relay and still have good voltage at the pump.

Use your old pump supply wire to operate the relay, provided it has a reasonable amount of voltage.
Reasonable being anything over 12 volts with engine not running.

 

Not that it matters at this point since you've already made the decision, But I've been using the Carter pump trouble free going on 6 years.

 

Brush,
Our Carter P4070 flows 72 Gallons Per Hour which can supply a 400 HP engine.
Our Carter P4600HP flows 100 GPH and will take care of over 500+ HP.
Both come with all the hardware and mounting brackets that have rubber insulators between the bracket and the pump.
They are extremely reliable and quiet.
Yes, I work for them.........but I have had them on all of my HotRods over the last 30 years, and never a failure.
Please, be certain to install a good, high quality fuel filter between the fuel tank and the fuel pump. The crap that comes out of the gas pumps is dirty, and will damage or ruin fuels pumps fast.
Let me know if I can help you out in any other way.

Install a good quality ball valve between tank and filter so as to make filter maintenance easy.

 

I agree with the fuel filters...I put them before every component in a fuel system on my own cars, there were two inline filters on the old 49 and the screen in the carb!

Locate one filter between the tank and the pump, one just before the regulator, and one before the carb if it doesn't have one built into the fuel inlet like most GM carbs do.

Yes...the Carter 4070 is an EXCELLENT pump, but I'd recommend running a pressure regulator if you're not already. Before I had the Vara-Jet carb rebuilt on my old Chevy, I had issues that I thought might be related to excessive fuel pressure. I put a gauge on the fuel line after the pump and you should see how the needle jumps around! It wavered between 6psi and 9psi like mad! I installed a Holley regulator and set it to the desired pressure using the gauge after the regulator and was able to dial in a smooth, rock steady 4.5psi.

(Most carbs can handle the pressure that the Carter 4070 delivers, but a regulator smooths the erratic pulses out and delivers a steady pressure to the carb...no wild pulsations working against your needle and seat. I like the idea of having a regulator, even if some will say you don't really need it.)

 

I wish I had this info about a year ana a half ago. MY Holley is noisy as hell, and IS rubber mounted and clost to the tank! I hear it over the Exhaust and the Gear Drive! I hate it.

CAn someone post a pic of the Carter? WIll it bolt up and have the same inlet and outlets as the Holley? Or am I gonna have to get an adapter to make up length in the Fuel Line, or will I have to shorten ones side of my fuel line?

Either way, getting rid of that racket will be worth it.


Thanks.

 

I'm glad I read this. I was all set on going with a blue holley with the regulator. Now I'm looking at getting the carter p4600hp. Should push enough fuel for a planned future blower upgrade.

 

One last comment about pressure regulators. While Holley is a very popular one, Mallory's regulator is a much better design based on the tesing our engineers have done.

 

I like mine....

 

Here is a picture of the Carter P4070

 

Is it worth the extra 50 bucks though?

 

Yes... I don't know what is happening at Holley... but I think their quality control dissappeared...!

Cadillackid just had another Holley fuel pump failure and I've experienced a couple of fuel pump failures and a Regulator that wasn't maintaining the proper setting as well.

I'l be buying a Carter or Mallory setup for my roadster...!

 

My stock mechanicle just died so i was glad to see all the good info. Thanks guys-

In doing my own further research theres also some important info about the regulators. There two diferent stlyes- non return and return. Basically one acts like a damn and only lets your desired amount through, and the other is more of a valve that returns excess fuel and pressure back to the tank. Seems like some of the noise could be from the pump stacking pressure against a non return regulator and working against itself. All the less expesive ones are non return, and the expensive ones like the mentioned mallory are return type. For most applications i would guess both would work fine but with as pricey as stuff is getting like engine rebuilding seems like cheap insurance. The only downside to the return setup is just that, you need to put it after the carbs and then run a line at least to before the pump and at best in the tank. So for me the challange will be figuring how to make it not stand out on my olds and the bennifits will be a consistant fuel system designed to last and more importantly work all day every day.

Most likely over board but i hate spending money twice so i tend to make things bullet proof.

Im know expert but it makes good sense-
