Default 75 fuel filter

Hello i have a 75 I just wanna verify that this is my fuel filter. Is there a paper filter in side or this whole unit need to be replaced?

First, that filter assembly is an Aftermarket piece ... inside that screw-apart glass-potmetal housing ... you see a caged white plastic cartridge integrated with a plastic mesh.

If ... IF you still have car's Original Quadrajet carb ... it is was factory-equipped with a small fuel filter Cartridge just inside where fuel line screws onto carb body ...
... that cartridge is either stamped steel with pleated paper or sintered bronze.

Unfortunately, someone has hacked up your fuel line and installed that aftermarket filter (not good). If you still have a Q-Jet carb, buy a new reproduction steel fuel line, throw that thing away, and replace your in-carb filter. Make sure you still have the spring. NAPA part number 3052 for the good filter.


...But I'm going to bet that they didn't just hack the fuel line - based on the angle of that rubber line that they installed, I'm betting they also removed your Q-Jet carb and installed an Edlebrock carb as part of the "mod" job...

I canot tell which carb you have because it's covered by air cleaner assembly.

Remove top lid, air filter element and lower base ... then take pic of carb.

Lars probably right ... Qjet probably gone.

Can't see the carb because you have the air cleaner in place, but it's certainly not the correct Q-Jet. Someone has hacked something together that's not right...

Those glass filters have the cast threaded rod that holds one end into the other and are probably one of the most dangerous filters ever made. Vibration will make them pull apart at the threads causing a massive leak which would be spread rearward by your cooling fan. I actually had one pull apart years ago.... I would not trust one of those on my lawn mower. I still have one that I use between the pcv valve and carb to test if oil and how much is being sucked past the pcv but other than that, they are one of the worst fuel filters you can buy. The rubber line isn't right either but remove the filter.

That's true. But I think Lisa has more problems than just the filter. If she can post up a photo of what she's got on the top end of that engine without the air cleaner, we can see how much of a problem she has, and what she needs to do to get the car in safe, driveable condition. Replacing that filter will be top on the list, but the aftermarket, incorrect carb under that air cleaner will determine how best to manage those frightening rubber fuel lines and other problems...

You can replace that filter with any in-line fuel filter with 3/8" hose nipples. Avoid the glass filters. These types of "generic" filters are available from any auto parts store - don't tell them you want a filter for a 'Vette, because you'll get the in-carb filter shown in my post above - you just want a generic, aftermarket, in-line filter. NAPA has one under part number NOE 7401158 for about $5. This is a clear nylon plastic filter housing with a sintered bronze filter element and a lifetime warranty.

Be aware that, depending on the type of carb you have, that the carb itself could have an in-carb filter. If you have an in-carb filter, you need to remove it if you are going to use the in-line filter - do not run 2 filters in the system. You might want to check that...

Ah, ok. An aftermarket carb that requires a filter. The filter you have can be removed and comes apart for cleaning. That is one of the big problems with those filters as they have seals that can leak and are very cheaply made. You might consider a generic one piece canister filter with 3/8ths" inlet and outlet from your local parts store that would be a bit safer or you can just unscrew it and clean it out.
