No brainer, buy it for 350 cfm carb.
Works great a year later. Using on a 350 CFM ROCHESTER 2 BBL I just wired it up to ignition hot using a relay and in line fuse. Works perfectly. Did NOT need a fuel pressure regulator. Roller cam motor that did not have the cam-lobe to run mechanical pump. I have had zero issues with it in a year, daily driver. I mounted it in front below front bumper where it gets plenty of air. Fuel flows from a fuel cell that is higher than stock fuel tank, so it gets plenty gravity feed. You should place pumps to push fuel not pull. But this one works fine pulling the fuel, then pushes fuel upwards to carb. Cheap, easy, works, no brainer.

Word great on old ford 60hp gas tractor
Installed this today on my 1975 ford 4500 industrial gas tractor. The old mechanical pump worked but was leaking really bad and it's kind of a mess to get a new one in. Enter this pump. Because this is a carb, technically an updraft as well, I wanted to get something around 5gpm. While I don't have a gauge on it, it idled fine and I ran it for a few minutes at a fast idle with zero problem, no indication of flooding or going lean. You can hear the pump, but not when the engine is running. Granted tractors are loud. I would say they are not much louder than an in-tank pump. Time will tell on the reliability, but I liked how this came with a plastic mounting base which was more substantial than the stamped steel ones that some cheaper pumps used. Size wise, don't forget to add on the piece that screws into the pump. I'm not sure if it is a pre-filter or not (I just used a wix before this) but I mention the piece because it does add a decent length to the install. My pump install was not taxing for the pump because the bottom of the tank ran downward a few inches to the filter, then flat a few inches to the pump, and then the pump ran the pressurized line perhaps 2 feet to the carb. More than likely a lot less of a load than if you were to install this into a car. So far I'm very happy with it, seems like a great value.

failed in 10 minutes
Very disappointed. Worked great on trial setup. Then, rerouted hoses & wiring for a permanent installation - put everything back together and it died to pump no more. It has TEN MINUTES of total run time and is dead. I bought it three months ago & it had sat on my desk until I had time for the project, so return window is closed. Glad I wasn't miles into the woods when it failed.

Good pump at a fair price
Has a little to much pressure. It says 5-7 psi but it has around 12 psi. Used a regulator to cut down 5 psi seems to work well. My pump is mounted on the frame rail below the tank to be gravity feed.

A good fuel pump so far!
This seems like an honest electric gas pump! Other brands do not allow or mention a distance which they can pull fuel from a tank. This one at least states not more than 7ft above, which is very good information, because I had to install mine in the engine bay for now! It primed and after the filter and floats filled up, my 351 roared back to life!

Works great when installed correctly
When first installed I put it in the engine bay right by the mechanical fuel pump, took a while to prime and fill carburetor. I re-installed the pump back by the fuel tank like you are supposed to and pressure is much better and starts instantly. 1977 Dodge W100 with a carter afb carburetor

Lasted on 3 years less than 5000 miles of use.
It was good for 3 years and I only put 1000 to 1500 miles a year on my vintage GTO, then it just quit- still voltage to it but not working. Fortunately it died just after I drove into my driveway but would NOT buy it again as longevity is terrible- if you do buy, order a second one to keep in your trunk so you won’t get stranded!

Great for the money!!
I put this on my Jeep YJ with a 350 Chevy conversion and it is working great with my Holly 650.

Me parecio una buena refaccion, lo instale en una ford f100 1971 con motor 6 cil en linea (4.9) ahora mi camioneta enciende de inmediato como un vehiculo moderno. la instalacion es simple, solo es conectar la bomba ala manguera lo mas serca del tanque como si fuera un filtro, la instalacion electrica tambien es simple con un relevador, un fusible y un cortacorriente.

Es rápido para dar una opinión de calidad y durabilidad, pero los materiales se sienten de buena calidad y la bomba no es ruidosa a comparación de una "generica"

Buena calidad y presión de gasolina lo malo que no fue para mi vehículo por la presión que maneja pero se ocupo para otro y esta trabajando muy bien

Pumps really well and super quiet. Unfortunately the pressed in outlet side of mine won't stay seated and leaks
