depends one th eflavour of cp3. with some it is not adviseable to run positive pressure to fuel inlet, and definately not in the amount that a stock cp4 liftpump provides.

reason for this that some cp3 have the case pressure relief back to inlet, and some to the outlet. if its to the inlet, the case pressure will rise 1:1 with feed pressure and this will make the metering valve flow very different as what the will believe it flows.
