Fuel PSI issue??
using a walbro pump,air dog 150, sump, SD regulated return with stock fuel filter removed, Isspro fuel pressure gauge set @64PSI..what I have noticed lately is the pressure will start at 58 psi and slowly build back to 64..with this set up I have never seen a pressure drop at WOT and still don't.
With RRE around the corner, is this a beginning of a pump issue?? filters have less that 9000 miles..suggestions??

With my fuel pressure being read electrically, I see some variance at times. Once it stabilizes, it reads very closely to my set pressure. I use it for reference, but don't always put a lot of stock in the numbers. I have seen the pressure read ~10 psi higher that my set pressure of 62 psi, but never more than a couple psi less. I don't see how it can read higher than the set pressure. There are no restrictions in the return to skew the numbers. Go figure.

I guess its time to call Clay and get a new sending unit..
