Walt and group, I took my original radiator out two years ago and had it cleaned and I cleaned all the leaves and crud out between the condensor and like I said I haven't had a problem. No overheating and no FP problem. But, As sure as I'm saying this, it will come. John Hervey << John, do you by chance have an all metal radiator with an extra row of cores? This might drop the temperature of the returning coolant by a few degrees and keep your fuel tank that much cooler. I'm still running on the OEM radiator and haven't had time to change it out. >>
