For the past few weeks my car started to run rough and would die frequently. It got to the point where it would not start. The first thing I did was to check the fuel pressure. The instant I turned on the ignition key the pump would run for the two seconds and the fuel pressure would read somewhat normal but the instant the pump stopped the fuel pressure went right back down to zero. The next thing I did was to hook up the fuel pressure gauge to the inlet fuel rail fitting on the passenger side. When I ran the fuel pump the results were the same so that pointed that the problem was the fuel pump in the fuel tank. Today I dropped the fuel tank and found out that the rubber hose that connects the fuel pump output to the fuel pump hanger output tubing was all mushy and the hose had burst, thus little fuel pressure. In Hawaii we have ethanol mixed with gasoline and was wondering if this is why the fuel hose material disintegrated. Does anyone have any suggestions as to what kind of material the fuel hose should be made with? Thank you for any suggestions.
