Q: Should I buy the 550HP pump or the 1100HP pump?

A: If your car is street driven and the engine produces no more than 550 horsepower, the 550HP pump will work fine. If the car is primarily used for racing or if the engine produces more than 550 hp, the 1100HP pump is a better choice. The 1100HP not only produces more volume but the pressure is higher so that a regulator can be used. A high pressure pump used with a regulator will provide steadier pressure than a low pressure pump.

Q: What if I buy a 550HP pump and later find that I need a 1100HP pump?

A: Any 550HP pump can be upgraded to 1100HP specifications for $50. Email us at robb@robbmcperformance.com for more info.

Q: Do I have to use a pressure regulator with the 1100HP pump?

A: Yes

Q: You don't list a pump/starter/sending unit for my car. Can you make one?

A: In many cases, yes, and often for only slightly more money than one of our standard units. Email us at robb@robbmcperformance.com with your requirement for more information.

Q: My car has a small 1/4" factory "vapor return" line that was connected to the factory pump (or fuel filter) in addition to the inlet and outlet lines. Can I use this line with a RobbMc 550HP pump?

A: Yes. RobbMc 550HP pumps come with a metered port and fitting to accept a 1/4" rubber "vapor return" hose. A plug is also supplied for those applications not using a "vapor return" line.

Q: The 7 psi produced by the RobbMc 550HP pump is too high for my carb. How can I lower the pressure?

A: If your car is equipped with a 1/4" factory "vapor return" line, connect it to the pump using the supplied fitting to reduce the idle pressure by about 1 psi. If your car is not equipped with a return line (or you need even less pressure), you can add a non-return style pressure regulator (such as RobbMc PN 1050) between the pump and the carb.
