New to us 1966 Catalina Convertible - fuel pump and filter question and rear courtesy lights question

[TOG1937]

A mostly original survivor car right down to the original points distributor, "GM" 2 bbl Rochester carb and original air cleaner. Engine appears to be matching numbers. Fuel pump appears to have been replaced not too long ago. We replaced the 3/8 fuel line to and from the mechanical fuel pump and installed an in-line fuel filter ahead of the carb. The fuel filter never even come closes to filling but the car runs great and strong.
Any reason to be concerned about this?
Anyone know what the correct light bulb is for the rear courtesy lights in the lower door cards?
THANK YOU!

did you check for the factory fuel filter in the carburetor inlet?
Those clear filters tend to show not full and personally, if made of plastic, I would replace with metal.
Did you check if owners manual had the bulb number? Otherwise check the Sylvania auto bulb web site.
Really nice looking car.

Will check the integral carb filter, good thought. No owner's manual. Thanks for the tip on the Sylvania website! The courtesy light bulbs are "90"s. Found a pair on Ebay.
