Force fuel pump

[rl29]

Was wondering what cylinder does the diaphram on the fuel pump run off of on a 1987 force 125.

Re: Force fuel pump

I think your motor is equipped with two pumps.If so, the lower pump is operated by #4 and #5 cylinders. It also delivers the fuel to the upper pump, which is operated by #3 nd #4 Cylinders.

Oddd1 or 12footer:<br />So how low can the compression go before it would affect the pump. Also would that be what they would call leaning the carbs out.
