The reason the FL-1A will not fit: A previous owner installed a 1965/72 Galaxie/LTD 240 oil filter adapter (C5AZ-6881-A). It's not the same adapter as used on an Econoline 240 (C5TZ-6881-A).
Short FL-1A = FL-300 oil filter. Originally designed for use in 1975/78 Mustang II's w/a 302.
There wasn't enough space between the engine cross member and the oil filter adapter to use the FL-1A, because Ford shoehorned this engine into the engine bay.
Thank you sir. I'll check out the adapter at the next oil change.
