Engine/Transmission (1998.5 - 2002) Question about fuel pressure regulator install...

[wlowe]

I recently installed an aeromotive fuel pressure regulator, (model 13301). I have a pusher/oem pump combo and I wanted to drop the pressure from 23 psi to around 14 psi. I installed the regulator between the fuel filter and the VP44. Works great, my pressure is now 14 psi.



This is my question. After the install I started thinking about it and realized that there is a constant increase in fuel flow through the filter because the bypass in the regulator returns fuel back to the tank. Will this hurt anything. Can the filter hold up to this constant increased flow? Should I have installed the regulator between the OEM pump and the fuel filter? Anyone else install their regulator between the filter and VP44? Thanks for the help.

On the glacier system the instructions called to install the regulator 18 inches from the pump toward the filter

You might have ben better off to install the by-pass before the filter. The less pressure going through a filter the better as far as trapping contaminates is concerned.

And more important water separation.

After doing some research on the TDR I came up with this info. The stock fuel filter is rated at 60 GPH. The stock lift pump is rated at 100 GPH. I'm assuming that running a pusher pump in series only increases the pressure, not the volume, so my system is still putting out 100 GPH. As I said earlier, my pressure regulator is plumbed in between the fuel filter and VP44, bypassing fuel directly to the tank.



My first question is, if the regulator is bypassing enough fuel to lower the pressure from 23 psi to 14 psi, how much is it increasing the flow through the filter.



My second question is, if the regulator bypass is increasing the flow through the filter to 100 GPH, (not sure if it is but I guess it's possible), will running 40 GPH over the filters rating affect the filters efficiency or possibly damage it?



Thanks,

Bill
