I have a 93 with a 5 speed, 167k on it. Is it recommended to run a fuel pressure gauge? I plan on ordering one and am coming across two types of pressure fittings to hook up the gauge. Do I need this auto meter 3279? http://www.amazon.com/Auto-Meter-3279-P ... el+snubber
or do I need this from Geno's http://www.genosgarage.com/12MM-CUMMINS ... yUzjoVhp2E
