Ben, you don't state what your pressures are. However, I recently used a fuel pressure gauge (bought from JC Whitney) and determined that my WUR had a clogged filter and was not allowing the fuel pressure to drop (control pressure). The system pressure and control pressure were the same (93 psi), which should not be the case. I took the WUR appart and removed the clogged filter and after re-installing it, the control pressure dropped to 50 psi. I recently removed my fuel pressure regulator (back of FD) and removed some spacers and my system pressure is now 75 psi and control pressure is 43 psi. BTW you can check if your WUR filter is cloggged by disconnecting the return line from the WUR (not the line from the top of the FD to the WUR) and running the pump (engine off, cold, and disconnect WUR electrical plug) to see if gas comes out of the return line. If it does not, it means that the WUR filter or the return line itself is clogged. As always, one must be very careful with testing involving gasoline. Hope this helps or let us know what your pressures are so that we can help with the troublesooting. Thanks
