I have five of these 1.5 in. bottom thread 1/8"NPT pressure gauges previously spec'd for a fuel pressure gauge. They're brand-new, and have no other hardware - you will need to adapt the threaded portion to either a pressure hose or a direct connection to the fuel rail using a schrader valve adapter. Selling all five of them in one sale, $60 shipped via paypal only. I don't want to sell separately, as shipping would be cost-prohibitive...
