I checked the 95 this morning for a comparison point. It'* even worse.....BUT it doesn't have the fuel demand the 93 does. I'm still totally stock on the 95. I'm not sure either regulator is truly bad yet, but the pumps are certainly weak on both cars. Not surprising when you consider the 95 has more miles than the 93.
And keep in mind, I ran at Woodburn in the 95 with crappy fuel pressure. VERY crappy.
I'm looking at the Walbro, but I want solid numbers for comparison between pumps first, both Pressure and Flow rate. OEM vs. Walbro, considering they're basically the same price. Also, IIRC, the Walbro has an adapter harness that has to be spliced in, and I'm not sure if the strainer sock (OEM) attaches to it. I've got some feelers out on this stuff.
