If you are referring to the electric Stewart Warner fuel pumps in the trunk, they did use filters, but you didn't always run with the pumps on and the main line bypassed the pumps and went tank to carb so the cannister was necessary. Mechanical fuel pumps on the motor which were also use in the set-up did not have a filter.
Long and skinny....
The filters in the electric pumps were too restrictive and hindered flow. The cannister filter was designed for trucks and was a terrible design thet also had poor flow.
Solution..
Throw away the 240A filters and run without. Use a filter in the tank from fuelsafe that is part of the road race set-up.
Use a staight though tube at the cannister to keep the look and bypass the inner works.
Install 2 in line hi-po filters under the car.
Yopu keep all the real looks but do not disrupt the flow while keeping th moptor clean. The hi-po's are easy to clean and you will be happy
