Fuel Pump and TPS
Just a wild question here guys, but is the TPS position relevant to how much pressure the pump is putting through the lines on TPI?

Re: Fuel Pump and TPS
nope. only thing that alters fuel pressure is manifold vacuum, as vacuum goes down, pressure goes up. (higher throttle opening equals higher fuel pressure.) TPS is completely uninvolved.
