Well I just picked up a 0-100psi fuel pressure transducer from the local speed shop. Then stopped at the local scrap yard and grabbed a late model TPS connector to plug into it. Now does anybody have any idea which wire goes were? Do I give it 5+ volt signal or 12+ volt?? The guage is another like 100 bucks, forget that business. Any info on it would be great!! Need to get that fuel pressure up, my DC is 95% around 4200rpm.. And to top it off my holley TB is toast, The shaft bearings are shot and it drips a tiny bit of fuel out. I am on the hunt for a 454 unit now.

The sensor that you pickup up at the speed shop was probably made by Kavlico and operates of +5 Volt rail (0.5 to 4.5 Vdc), model P155. Take a close look at the data sheet and compare against your unit...

I hope this helps.
