the Biggest problem Oversight I SEE many PEOPLE do is to have a fuel filter in place that is not rated to handle the flow of the pump itself....
i feel diagnosing a pump is fairly easy based on what frank said ...just be sure that you pay close attention to the flow rate of the filter and place it before the pump..
another thing i have also seen people double filter their fuel system ( filter before the pump and one in line somehwere before the motor)....my question is WHY would you do this.?..it can only cause a disrupption in the fuel flow ( restrict)...
i am probably one of those guys that has a LARGE over kill pump..i run the PRO-STAR MAGNAFUEL on my naturally aspirated 511 bbc....of course its adjusted to my fuel level psi i need....but we have a nature as dragracers..and that is we want to make more power and go faster and faster..unfortunalty if you undershoot your fuel pump you will be buying another fuel system when you up grade your performance.....this includes running any NOS in the future....you simply outgrow it !
i am a living testament to this story..placing the pro-star magnafuel on my 511ci bbc with a pro-system in line pro micro screen fuel filter might have been over kill at the time ..but it kept my door open to running NOS without having to run a dedicated fuel system which invloves buying another pump,regulator and pluming etc.....
Now i have decided to try alcohol...so my once overkill magnafuel pump and its #12 line to a #10 line is just perfect for my alcohol swap...would have been the same difference if i decided on a 300 fogger or plate, or if i decided to go from my 511ci motor to a 632ci...i got enough fuel pump there to handle it ALL mentioned above
i guess what i am saying is spend a little more up front to have a bunch of options at the end.........spend 200/250 for a pump that can put out exactly what yoy need and NO more...or spend 200 more dollars and never have to worry about out growing the pump....if you are a true racer you will get there i am satisfied..
however its
buyers choice...pay me now pay me twice later....what will it be ?
