Now that's funny!!! You guys are a riot. I'm sure glad all of you have a sense of humor, it makes life a lot more interesting, as shown here, and it makes it a lot more fun, too. Thx.

Yep, dpollo, there's at least a couple of us still around and kicking. And Yep, I'm a real doctor, albeit a retired one. So, (here's a long-distance diagnosis for you . . .) unless one can see light when looking into one of your ears, and you've definitely got something between your ears to block the light. so you're definitely OK. Thx.

Wow!!! I had no idea that my question would generate such great dialogue. Dpollo's correct about vacuum, and what it is, and what it isn't. To expound upon his initial thoughts - vacuum's a space devoid of matter. a vacuum, or "free space", is any space where the gaseous pressure is lower than atmospheric pressure. In quantum physics, even if all matter could be removed from a given space, it still wouldn't be totally empty due to vacuum fluctuations, dark energy, gamma rays, cosmic rays, neutrinos, and other such phenomena being present within that given space. now, whoda thunk that a question about a fuel pump would generate such thoughtful discours. is this great - or what? Thank you everyone!!!!

To One And All - It looks as tho' I've generated some significant conversation, and that's a Good thing. All of this just reinforces my intent to relocate the canister filter from the front fender liner to the rear of the car near the fuel tank, where it probably should've been installed in the first place. So, I'm going to correct/improve some well-meaning person's installation at my first opportunity. I thank all of you for your valuable input. Thx.

Thank You for your response. I've thought about moving it back near the fuel tank. I had a '65 Pontiac Catalina full custom (chopped, sectioned, channeled, lowered, restyled, the "whole nine yards", as they say . . .), which had a supercharger on the engine. I had to run an electric fuel pump (Stewart Warner #210(?)) right by the fuel tank. I put a large Fram fuel filter between the pump, since it was quite expensive, and the tank, and never had a problem. So, that's why I think that's probably the way to go, and your opinion reinforces that decision. Again - many thanks for your input, I really do appreciate. Thx.

QUESTION: Will the mechanical fuel pump on a Plymouth 218 6-cyl flathead pull fuel uphill? SCENARIO: 1946 Plymouth has: 1) ACDelco glass bowl fuel filter mounted just in front of carburetor; 2) ACDelco (#GF-62) canister-type fuel filter mounted near top edge on right inner fender; and 3) new fuel pump (Airtex #73201). Pump pulls fuel from tank, up approximately 16" to/through canister fuel filter on inner fender, back down into fuel pump, and then pushes the fuel back up approximately 18" to/through the glass-bowl filter, and into the carburetor. So, is this too much for the "pulling" side of the fuel pump to handle long-term/successfully?
