One thing leads to another. I put my 1972 Skylark back on the road several months ago after years of sitting. I had the 2-bbl carb rebuilt and the car ran fine for awhile, but now acts fuel starved and idles rough. I figured I would replace the fuel filter in case crap from the tank clogged it up. However the replacement filter (Wix 33044) seems too tall. The fuel line fitting only threads a few turns before bottoming out. The old filter is shorter. On further examination, it looks like the old filter was crushed to fit. Should the filter be crushed? What’s going on here? (Once I replace the filter, I'll come back here if the stalling and rough idle remain.) Thanks in advance.
That is definitely what is happening, the filter is getting crushed. There is supposed to be a spring in with the filter as well. Maybe the fitting is the problem. There are a number of fittings and filters for the 2G carburetor. Give Gregg Gessler a call. https://quadrajetparts.com/inlet-fittings-c-72_87.html
Many times the wrong spring is used for the filter. The filter spring is very light gauge wire and short. If somebody takes and uses an accelerator pump spring, or other wrong spring, then when you tighten the fitting the filter will twist up like that. I've seen it before often on Q-jets.
