The reason I ask is this: I used to get 20 mpg from my van. Or I thought I did. I never paid close attention to mileage, but I think I tested my mpg once, and I got 20 mpg. I recently had a new fuel pump put on. (in-the-tank fuel pump). The new fuel pump is calibrated for a 22 gallon fuel tank. My tank is a 37 gallon fuel tank. Production of the latter pump was discontinued, which is the reason I got the 22 gallon fuel pump. That's all fine and good. My fuel gauge doesn't operate the same now, but like I said, that doesn't bother me. What bothers me is that once the new fuel pump was installed, I am getting only 10 mpg. I have talked to a couple of different mechanics, and they all say that the different calibrated fuel pump wouldn't effect the mpg. The repair shop who replaced the pump says they don't believe I was getting 20 mpg. They say that 10 mpg is more realistic. Since I have never paid close attention to mpg until now, I really don't have a strong foundation to argue on. Does anyone in this group have a 300 ford engine? If so, what is your gas mileage? Again, mine is a 1993. Thanks. PD
