Customer Rating: Summary: It's a really bad pump. Comment: I also had two pumps fail after not even 10 minutes of operation each. This is a very simple application, with the carb only 4 feet away and 6" above the tank. Well within the spec of this pump. I checked electrical and fuel connections very carefully and did not run the pump dry.
The first time, I mounted the pump about level with the centerline of the tank (fuel flowed freely to the pump, as the tank was more than half full.) But it couldn't push it up the 6" to the carb. The second time, I mounted the pump below the tank. Fuel flowed freely through the pump both times, but didn't pump the 6" up to the carb.
This vehicle had a second fuel pump for its Hunter gasoline heater, of very similar design except 20 years old and rusted (and not made in China). I used this pump as my sanity-check. It was in roughly the same location, and if I connected the power and fuel line to it instead, the car ran fine. The vehicle is a Fairmont MT19 speeder, with an Onan 2-cyl. engine. Customer Rating: Summary: Mr. Gasket Electric Fuel Pump Comment: I converted a fuel injected BMW to carburetor, and used one of these pumps to replace the high-pressure pump. It's been working fine for well over a year, and mounted right in the spot where the former pump lived; just wired up to the existing pump wires.
I have a similar pump on my Citroën 2CV that's been there for over 10 years, and no pump failure.
In both cases, key to good operation is to mount the pump(s) as low as possible in the vehicle to have the pump 'pushing' the fuel, instead of trying to 'pull' it.
UPDATE: July, 2008
I had purchased another of these pumps to have as a spare. Today the car was having some fuel delivery problems (original Mr. Gasket pump that had been on for a couple of years). I decided to mount the spare Mr. Gasket pump. Like the other reviewers, I got about 10 minutes out of the pump, then it died. So I would change my star rating and lower it if I could figure out how to do it. Bottom line, I would not buy another pump like this. I think I just got lucky on the others.
Customer Rating: Summary: Mr. Gasket 42S Electric Fuel Pump Comment: I bought two of these pumps and the best I could get out of each one of them was 10 minutes. I checked the volts running to the pump and it was a constant 12 volts. I would not buy one of these pumps.
