I have to run an electric pump for my late model 5.0 - with 3-2 carbs (only need 5-7 psi). I had a Carter on another truck and it was loud as hell. This is for my RPU so I don't want to listen to it all day. I was gonna order a Holley "red" pump but I'ver never heard one running. Also, fuel line from tank to firewall - aluminum ? or steel? Thanks for your input...
I don't know about quiet but if you mount it on the frame, you'll get a sound transfer. Mount it on the frame with a thick piece of rubber and that should help some.
I use a Mallory Nascar with a regulator and bypass. (Mallory was a gift from my son, who selected it for its servicability. (In 15 years, I have replaced brushes once!) It is mounted with the rubber grommets that were included, along with a high zoot bracket. Whisper quiet. Recommended. (Jegs, Summit)
Word on here in many threads say that the Holley Red is very noisy. I have one and are now reluctant to fit it.
I have two Airtex 5-9lb pumps, one on each of my rods. I like them a lot. Just enough noise to hear them fill carb, then don't hear them again. Of course they are on bigger vehicles than yours, a 46 coupe and a 53 F100. These are inline pumps about the size of large filters mounted in rubber coated clamps on the frame rails.
Glad to hear that! I'm in the process of mounting an Airtex replacement pump on my OT car. Quiet is good!
Wrapping it in rubber, or radiator hose will make a huge difference. I had a walbro 255 in a OT car and at first mounted it NOT using the stock hardware. I had some fuel starvation issues in corners so I tracked down a stock mount that would work and used it. HUGE difference in sound. Before you could hear it over the exhaust (straight 3") inside the car. With the new rubber surrounded mount, you could barely hear it prime.
$50 at just about any parts store. Quiet, reliable. I put two in each car and a switch for each. If I am planning to race, I flip both on. When I travel or drive normally, I need only one running. If there ever is a failure far from home, I simply flip a switch and keep on driving. I haven't had a pump failure in many years. I do the same with my ignition modules.-- flip a switch and keep on driving. I haven't had a roadside repair in over two decades.
I have a Holley red pump on my 56 New Yorker, near the gas tank, hanging off the frame with a heavy piece of rubber (tire sidewall section). Before starting the car, I can just hear it enough to know when the needle in the carb closes. That's when I crank the motor over, and I never hear it after that.
mallory comp 140 = quiet and will feed alot of hp!ran one on a 406ci sbc with two stages 350 hp of nitrous ! fed motor and everything worry free and reliable!
Side by side - in parallel. At times when you have only one pump running at a time, the valves in the other pump act as the necessary "anti-drainback valve" to prevent reverse flow and pressure loss. When both pumps are on, you get double flow at the same pressure as usual. I run both pump outlets to a "tee", then one line forward from there. Both inlets to a "tee" then one line to the tank pickup (filter is there too, of course). Same pressure as always, and you have a choice of running either pump or both pumps. So you have safety backup, or double flow, depending on your needs. I used to have to carry a spare pump + tools on trips just in case. Not any more.
the only electric i have is on an O/T car..the exaust is loud enough to drownd it out once the engine starts. one thing i did on a friends car is i put rubber gromets on each mounting bolt..really helped isolate the vibration of the running pump to the frame of the car, it helped
Mods may kill this thread - I failed to do a search to find Norwells excellent 2006 thread. : - / BUt my carter whines alot too. I'm gonna do the by-pass regulator trick.
