Yeah I don't plan on using mine so realistically I'm sure we could figure something out
Picture of filter and valve please.Tore into the carb again today, after spending hours researching why I was having such a hard start and every answer coming back as choke or timing. Timing is 0° without ecm, choke is set (thanks Lars) again, everything as far as I can see is good. Back to more research, and an hour later find 1 little blurb talking about the fuel filter. What the heck, nothing to loose now, so looked that up too. And found a YouTube video showing exactly how to remove/install one on a quadrajet.
6 hours of research, days of tinkering and tweeking and weeks of hard starts boiled down to a 50¢ piece of rubber. The fuel filter check valve that was not in there when I got the carb rebuilt. New filter, no check valve. Bowl was siphoned empty every night, no wonder it wouldn't start with a simple pump or 3 on the gas pedal.
I've NEVER seen one of those anywhere. good catch!
Most places you'll get the filter on the right (no valve), the valve is that black thing in center which fits in the inlet side of the filter (left). Without that valve, heat and gravity will empty the bowl overnight, draining as far back to the gas tank as it can.
This is the long filter from late model Chevy Quadrajet, there's also a stubby version. Either one needs the same valve. Most filters off the shelf don't have the valve included, just the filter.
Me either, but it does have a slight restriction to it, so many ppl will pull the valve entirely for higher rpm performance needs or snip the spring coils. If using an electric fuel pump, you don't need the valve as they have their own check valves. But for stock application, it's a must or you'll be cranking for days and stomping the gas pedal just to get the bowl re-primed.I've NEVER seen one of those anywhere. good catch!
