I have e pump mounted on the frame rail with a clear fuel filter, and the oem fuel filter on the fender by the Ignition box, attached w zip ties to the cruise control cable.
On the 74 the clear fuel filter -no return on this model- is a bit forward below the windshield washer tank, and held by zip ties thru a hole on the inner fender.
Debatting about what type of see-thru filter to use due to strange observations.... the filter has collapsed, and not sure why, as it is after the fuel pump it is not overpressure or over vacuum, so I can only blame ethanol.
