Re: Glass fuel filter location?

Right before the carb is the correct place. They just removed the inverted flare tubing adapter from the carb inlet port and added a 1/8 straight or close nipple back into the carb port. Moved the adapter to the filter inlet, slightly rebent the tubing and screwed the filter on the other end of the added nipple. Not sure which filter you have but Packard did use a short bowl glass filter and if yours is a typical type sold today those are a bit larger and that could be why yours is closer to the manifold..

Today's gasoline is much more volatile than gas available then so there could be a bit more "boiling" activity due to heat. Whether it will be a significant change when the car is running and fuel is being replenished is doubtful. There may be an increased tendency for the filter bowl (and the carb fuel bowl) to empty out when the car is parked though. Depending on how often you start the car this could be an issue if the mechanical pump needs to pull a lot of fuel from the tank every time it starts. In many cases separately switched electric pumps installed near the tank have been added to help prime the carb before starting. This way the starter does not need to crank as long. For infrequently started cars a few seconds of the electric to fill th bowl and carb and then turning it off will often save a lot of cranking time.
