I got adapters from speed and performance for oil pressure and temp gauges and as far as fuel gauge I'm running a jaz fuel cell I had the wrong sender and gauge combo I'm running a 0-90 ohm sender gauge combo now and for a tach I used the lead of the new harness for it I had to run a signal wire off the high side vss for my speedo to work it's still giving me problems but never calibrated it yet the walbro fuel pump does the job got it from summit and found the -an fittings from them as well for it along with inline -an style fuel filter I made my flex hoses from filter to pump and from hard line to fuel rail everything else is hardline and bent to fit around my cnotch and inside the frame my fuel cell did not have two ports for vent and return so I used the vent for return and drilled and tapped the filler neck for vent
