The marine COMP PUMP 140 Series features the quiet Gerotor design and has a free flow rating of 140 GPH and must be run with a fuel pressure regulator. The pump assembly itself is a high efficiency Gerotor that provides stable output and pressure. The Marine 140 Series is internally bypassed and factory set to 12 PSI. The special design of the pump housing allows some limited adjustment of the output pressure. The Marine 140 Series include an integral mounting bracket for easy installation. [links]

Carter is another great brand for the premier manufacturer of fuel pumps. Carter P4070 is suitable for marine, off-road, and passenger car applications. It has a pressure between 45-60 PSI. This nice pump includes a lot of components like fuel pump, tank seal, strainer, grommets, and wire harnesses. It has multi-layer internal and external strainers that offer 40% extra dirt-holding capacity. The NPT inlet and outlet is 1/4 inch. here

Flow in GPH = HP * BSFC *(1 / fuel weight)
For BSFC(brake specific fuel consumption) rated in lbs per horsepower-hour, use:
0.45 to 0.5 for naturally aspirated engines
0.55 to 0.60 for supercharged engines
0.60 to 0.65 for turbocharged engines
For fuel weight, use
6.216lb/gal for regular unleaded
6.350lb/gal for premium unleaded
For example, here is the calculation for a naturally aspirated 250HP engine on regular unleaded gasoline. here

I need to buy a new electrical fuel pump but don't know which one I need. I am looking at one that has 30gph and 2.5 - 4 psi. I was told that this would be fine because most carbs. like running at 3 - 4 psi. Actually I was told this would be perfect.

Thank you all for your responses. here

Use the one he sent you, I am sure he understood it was for a boat and probably has more knowledge about what it does in the real world, and the psi rating is probably equivalent to what you had that quit working. Pressure only builds when the needle and seat are near closed or closed, and as long as they are in good shape and the carb floats are set correctly you will not have a problem. I was staying on the low side so as to not introduce a potential carb overflow situation. Sometimes a carb's needle and seat can get used to the falling pressure from an older pump and then when a fresh pump with up-to-spec flow is installed the needle and seat can get overwhelmed. The 5-9 rating will work, especially with 3/8" lines as pressure the carb "sees" is less than with the typically smaller 5/16" lines used on a car.

4) Consider an additional safety allowance for certain applications where fuel lines, filters, etc. create abnormal pressure losses (confirmation by testing recommended)
