Fuel pump question.

Has anyone ever shortened our stock 2002 fuel pump chrome rod trying to reduce the stock fuel pumps pressure? Yes I know an electric low pressure fuel pump is the proper way to reduce the fuel pressure for Weber carbs but I am just curious if anyone has ever tried this with good results. I would shorten the fuel pump end not the camshaft end if I ever tried this action.

That would lower flow, not pressure. To lower pressure, you'd want to use

a less- stiff spring in the pump. A neat idea, if you have a dis- asemble- able

pump....

Not sure about the BMW engine, but on air-cooled engines with stock mechanical fuel pump, you can use spacers to adjust the pressure. Several good articles from Hot VW's magazine have detailed this (also Bentley Manuals).

between pump and carb...

I ran a regulator like that for years, then took it off and noticed no difference at all with the 32/36 Weber...so I left it off.
