I've installed a cheaper electric fuel pump on the Wildcat, feeds a 425.

I just came across the Carter P60504, that has the filter - that mounts
between the fuel tank and pump.

The P60504 only puts out 4lbs of pressure. Is this enough for the 425?

I also had a glass filter in the fuel line at the carb. If I install the filter
on the other side of the pump, can I do away with the glass filter. -
would the small glass filter, with the replacable element, be adequate
between the tank and pump?
Thanks
