Just tell those that question the location of the glass/plastic bowl it's a Jeep thing and Jeeps are not your conventional vehicle, they're special. They may stare at you in wonder or just walk away while you just grin at them.
Or, you could point out the pump mounting shape and ask them how they would put the pump on any other direction. Don't offer any more than that and just stare at them with a grin.
Funny this was mentioned. �I just got done �(20 minutes ago) installing an old �(new to me) Carter fuel filter. �I've seen others with this set up, and just had to have it.
I set this up a bit different than you will normally see. �I turned it 45 degrees coming out of the Carb. �It just seemed to fit a little better this way. �At least in my Willys.
A sediment bowl is an entirely different thing than the fuel pump bowl. Like your friends said, they usually mount so debris and water stay in the bottom, and fuel is drawn off the top. Your pump originally in WWII had a metal bowl, and someone decided that seeing inside the fuel supply was a good idea, so the glass bowl replaced the original design. It is more useful to see if you are getting fuel flow than as a filtration device. Now there were Carter and AC and other brand fuel filters that mounted to the carb that were more of a sediment bowl design.
After 7 months my rig made it's maiden voyage down to get a full tank of gas. I ended up showing the engine to two older guys during the trip, and that's when the questions started.
These old timers said i had the fuel pump in upside down on account of the bowl being on top of the fuel pump. Adding that any car they ever had with a glass boowl had it facing down, so my set up must be wrong.
Now we all know the fuel pump is set up right and not the issue.
But for future conversation can any one provide any logic as to why the bowl is on top.
