Are there any aftermarket pumps that are worth using in place of the OE? If not, what is the complete part number for the OE replacement.

Also, what should I expect to pay for a new pressure regulator. Part number?

I have been having some wierd starting problems lately and everything points to either one of these things. I just replaced the filter with another 300ZX filter and things got a little better but I am still having some trouble. I installed a pressure guage inline between the filter and reg. and am getting about 35 psi with ignition on, not running, and about the same with engine running. According to the Haynes Manual the ignition on, not running pressure is low by about 10 psi.

I have a '95 GLE with 129,000 miles and all the goodies...

Any suggestions would be appriciated.
