Title: 1973 Cheyenne C20 - 5.7L 350ci 4BBL | Fuel Filters
Post by: BADGE73 on August 03, 2020, 12:24:06 pm
Fellas,

This is driving me mad and I need some help. My truck is in serious need of replacing both the fuel filter at the fuel inlet on the carb as well as the inline fuel filter on the fuel line under the bed. For the life of me I am getting mixed information all over the place on part numbers and what have you. I keep hearing to make sure the fuel filter at the carb has a check valve but none of the ones I find for sale that fit have a check valve. I also cannot locate the correct fuel filter for the line under the bed. Ahh!!

This is the short filter with check valve.

Can anyone help me with locating the inline fuel filter that run under the driver side framing?

There is no inline filter for your truck. Just the carburetor inlet filter.
