Finally started the beast for the first time after the rebuild. Tach is not working which I'll get to but another concern is that the new Holley Red pump is quite loud when the key is turned on. Of course once it lights up you can't hear it anymore but is this pronounced HMMMMM normal or do I have a bummer Hollley?...Joe

Joe,
my Holley Red is quiet as a mouse, and that's with the tank off, and
engine not running. I bet I will not hear her at all when the tank is mounted. But I think some pumps are a little louder than others - that's normal, and don't mean your's is not ok - it's just a little louder. My old stock pump was very loud, too - but didn't failed until I changed to the Holley. I keep the old unit as a spare. BTW - I pulled the stock pump out of the round bracket and noticed a decal on the rear side "Automotive fuel pump- 5.5psi to 9psi" .... hmmm...9 psi? :shock:
Did you mounted a fuel pressure gauge? If so - what pressure do you
read? My one produces a pressure of excactly 5psi - just perfect for the
Quadrajet. I'm very satisfacted with the new pump.

Joe,
some thoughts - your pump doesn't have contact to the frame, tranny housing or such? And did you used the rubber pad for mounting the pump? And didn't you tightened it too much? A too tightened rubber inlay can't work as a vibration dampener and transfered vibrations can make loud noises.
Another thing I would like to tell about the Holley pump is that they highly recommend to use a filter in the inlet line to prevent the pump from debris. The same words are written in the instructions of the carb. "Use a filter between pump and carburetor". Therefore I use two inline filters. That's a cheap insurance for pump and carb. The carb already has this small filter in the inlet, but what a pain in the ass if this mini-filter is plugged when you are on a long tour. I decided to use two filters a while back when I got my bike after I found a tea spoon of red sand (I think from sanding the tank) in my inline filter, and a totally plugged mini-filter in the carburator. My Boss buddy Andy found the same red stuff in the fuel filter of his 502. And all this sand went thru the fuel selector valve first.... :? This spring I'll flush my tank several times with fuel before I mount it. I bet there is a lot of sand and other **** in it.

I posted this on the Yahoo site also, but has anyone tried the Carter AND the Holley Fuel pumps?? I have a Carter now, and it's pretty loud, so I bought the Holley thinking it might be
quieter, but haven't installed it yet. Now I'm wondering if it's worth
it "noise wise." I can't hear it after I start the engine, but it's
that loud Raaaaaaaaaaaaa when I turn the key on that I don't care
for. Hey......ya gotta tinker with something! :lol: Thanks.....Don B

Don,
You ARE bored :lol: Cripes if you can't hear it with the motor running, what's the rub?? Although I can picture you sitting on your roller stool with a Bud in your hand listening to the fuel pump for hours on end 8) :lol:
Just kidding.
My Carter is not as loud as the stock pump was, but we have them mounted from the frame cross-tube in front of the battery and they are mounted on rubber grommets. We thought they would have better air circulation there, plus they have no contact with the power train for heat transfer. With the stock battery they were close, but once we changed to the dry batteries we had a lot of spare room.
Still not running a pressure regulator and have had no issue with the carb, pump or NOS......

Loaf....will try the rubber pad if I can find it. I really don't care too much about the noise which is gone once the motor fires up. My only concern was that I got a bad pump and I don't think so from reading the posts. I did place the fuel filer on the inlet side so that is not an issue.
By the way...talking about quiet...the late model water pump which I installed is absolutely quite Do you have this unit?......Joe

Guys,
Actually my winter went better this year. I put the damned bikes in my trailer and backed it into the back of the shop so I couldn't get to them :lol:
It really is easier if you don't have to look at them every time you go in there. :wink:
Every once in a while I look in there and it just drives me nuts
Was going to drag them out this weekend to start the 'get ready' projects, but it started snowing at noon.....temps below zero last night and tonite......
sucks :x Oh well, need to get them out so I can do some wiring inside the trailer and add some amenities for the coming season.
Think maybe I'll spend time jazzing up tha trailer instead of the scoot.

I had one. I bought it a while back from the factory. When it arrived here in Germany my buddy Wolfgang (98' ZZ4) called me and told me his waterpump is going south. Loud noises, small leak...in short words - I had to sell the little beauty to him. Didn't had the chance to hear it, but it looked NICE. He installed it, but didn't tried it until now, and will not until middle of march, cause he's in Florida for the bike week.zenbiker said:

my Holley makes a quiet Bzzzzzzzzzzzzz when I turn the key on, and it's totally quiet when the pressure is build up, but I will ask my buddy Andy from Cologne tomorrow, who has the carter pump mounted this winter to his 502, if he can hear a loud Raaaaaaaaaaaa.....hehehehe....

I have the Carter pump mounted to my battery box without any rubber insulator. Wouldn't be surprised if that's the problem.
Guess I'll have to make up an insulator and, since I'll have the Carter off, I'll try both pumps. The quietest one wins!!
Thanks for the feedback guys! :capwin:

Don...I put the rubber pad supplied with the Holley Red under the installation bracket and the noise is the same. ****...once the bike starts I can hear nothing but my stroker motor. The bike performs flawlessly so screw the whole issue as far as I'm concerned. I think part of the noise may be the fact that it is inside my garage and wonder whether it would sound as loud outside ...Joe
Hey Joe,
Put the Holley Red on yesterday. It's quieter than the Carter. I can hear it before I start the engine, but it's not as bad as the Carter was. Of course, I couldn't hear the Carter either after the engine was running. What can I say........except I'm probably crazy. But then I have the right bike for my condition! Ha Ha............Don
