I want to test my fuel pressure to diagnose the overflow valve, lift pump, etc. The Haynes manual just says to use a 0-60 or 0-100 psi fuel pressure gauge, with a special banjo bolt adapter from the dealer parts department, yada yada.
Well, it is turning out to be harder than I thought to locate a fuel pressure gauge that is compatible with diesel engines. The only test gauges I can find at the auto parts stores are ones that say "not for use with diesel".
So, where do I find one? Would Snap-On or Mac tools or somebody like that have one? I suppose they would probably cost an arm and a leg.
Which brings me to my main question--Are the gauges designed for mounting in the cab (like Isspro, Westach, etc.) as accurate as ones designed for shop diagnostic use? I eventually intend to get a full set of in-cab gauges anyway, which would include a fuel pressure gauge, so if they are just as accurate I might as well spend my money once and just get the fuel pressure setup now.
Any advice/suggestions are greatly appreciated. Thanks,
