Fuel pump delivery pressure.......

suppose its is best to say the PMO regulator has less end of line restriction than the stock CIS system and therefore has less pressure to the carbs.


I had the same discussion with Vin several years ago about this same topic. I gave up convincing him about his flawed understanding how a pump works. His logic is flawed and I let it go unchallenged because he gave me something (gift). I feel some disappointment about his failure to grasp and understand his strong conviction about a PMO regulator raising the pressure.

Here is an example: If you connect a typical CIS fuel pump directly to a carb system, the flow rate or pressure would be too high for carb system to work. So people install a device called REGULATOR. The regulator does its job by reducing the existing fuel pressure not increase because it was already too HIGH to begin with.
