A few years back when I was building my car I started a thread on mechanical vs. electric fuel pumps. I had also read from other CC members of breaking down when using the Holley pumps. I was convinced at the time just to go with a mechanical pump so I bought what I thought was a tried and true Carter. A couple of weeks ago I took my wife for a ride and headed to Costco to get some gas, and I was sure I had two gallons in the tank. I made it within a hundred yards of the pumps. Luckily they had a gas can. Anyway after the ride I pulled my sender and took accurate measurements to check the accuracy of the float. Sure enough it was about 1/2" off so I fixed it. At empty I now know I have two gallons left. I siphoned the tank and then put exact amounts of gas back in and logged what the gauge read for future reference.
The next day I went for a Sunday drive by myself. It was beautiful day, no traffic, and I had my wide-band O2 sensor hooked up to finish jetting the carb. I pulled up to a light and the car died. I was going down hill so I coasted to the side of the road and called my wife to bring me some tools. Would you believe my tried and true mechanical fuel pump with less that 100 miles on it was bad. I hadn't ran out of gas after all, it was the first signs of the pump going out. Anyway I went down the road to the auto parts store and got a Mr. Gasket Rotary pump. I hooked it up in five minutes and drove home. I put in another bigger mechanical pump and now carry the Mr. Gasket pump in the trunk just in case.
