Hello everyone. Ok here is the deal. My 93 Ford E-150 with a 300 six cylinder used to get close to 20 mpg on the highway. I am not sure what it got in town. Recently I had a new fuel pump put on. The repair shop told me that Ford stopped making the fuel pumps originally installed on my 93 Ford Van. My van has a 35 gallon fuel tank. They said something about a transition year.. hell, I don't remember the technical jargon. The only fuel pump available now is calibrated for a 27 gallon fuel tank. They said it wouldn't make a difference except for the accurancy of the fuel gauge. So in other words, the fuel gauge reads full until the tank drops down below 27 gallons. No biggie. But I noticed that my MPG plummeted. I get 10-11 MPG in town ( I haven't checked the highway MPG). Everyone I talk to says the different calibrated fuel pump wouldn't make a difference in gas mileage. But I am not convinced. I'm not a freaking mechnic. And I live in an apartment complex that doesn't allow auto repair. But I'm considering dropping the tank myself, and installing an original equipment fuel pump (from a salvage yard, perhaps) to test the mileage. Is it possible that a wrong fuel pump can cause a decrease in MPG. The engine runs perfect. I recently got new plugs, new filters. What else can it be? I am so frustrated over this. I look forward to your thoughts and opinions. Mezzo
