Review on ๐ค Benefast Electric Fuel Pump 861155A3 for Mercury Mercruiser Marine Boat, Fits 4.3L 5.0L 5.7L V6 V8 Engines, Low Pressure Pump Replacement by Dan Quiceno
Incorrect pressure for carburetor
Didn't read the other reviews before ordering and hope to save someone some time. And to add, based on my research, this is not an issue with this particular seller, but it appears that all pumps currently available on Amazon that are listed as 'low pressure' also have this issue. Typical marine carburetors cannot handle more than 7 psi and these pumps operate in the 10 to 20 psi range. Probably works well for EFI booster pump applications, but will overwhelm the needle in the carburetor and instantly fill it with fuel. If you intend to use this pump to feed a carburetor, plan to install a regulator and built-in pressure gauge upstream of it.
- Outboard fuel pump, threaded on both ends, for Mercruiser direct replacement. This is a low pressure pump (8PSI-10PSI) suitable for carbureted engines with a fuel pump or some fuel injected engines that use a low pressure pump system.
- Not as good as it says
