I removed the fuel filter assembly on the North Carolina GTC I had at my shop to replace the filter. Normally, it can be done inside the car, but I suspected it was going to need a little more work than just changing the filter.

There was a lot of rust and sediment inside the filter bowl, and the spring at the bottom of the filter housing was rusted in place. It was no longer adding tension to the filter assembly so this may have been the source of the debris getting to the carburetors.

Oftentimes, this the bolt and washer assembly that secures the filter bowl to the upper plate will not clear the chassis during filter change, so the aluminum washer that seals the bolt can’t be replaced. This can be reused a couple of times, but will eventually leak. Pulling the whole assembly out allowed me to put new washer and chance to clean everything up.

I planned to bead blast the interior of the filter bowl after scraping all the old rubber gasket material that had fused to the assembly.

I got a new filter, spring and gasket ready for reassembly. I tried my best to preserve the original markings on the filter housing as it’s only original once.
