Do you have a gauge in there to see what its putting out? Usually they are fine, but when installed with the stock lift pump still running it may get a little high. The only real damage I could see resulting would be forcing the metering diaphragm to hyper extend. But unless your vp has been subjected to fuel press below 5psi, that shouldn't be an issue. A regulator wouldn't be a bad idea if you have one kickin around, but it should work fine without one. Main thing is to get a gauge on there and see what its actually doing, if you don't already have one.
