Yea I was out of town 90 miles from home when the car hiccuped a bit and a glance at my AFR gauge showed 22/1 for a couple of seconds then recovered.
It did the same thing 3-4 times as I was headed to the car show I was going to.
Once there I walked over a block to a place and bought a new Holley pump to toss in the trunk in case I needed it on the way home.
No problems driving home, but I obviously couldn’t trust it after that.
The fuel system was absolutely clean as was the filter that came with the pump.
It was mounted as recommended with a relay to power it so it had a good 12v supply as well.
My fuel supply system is 3/8 up and a metered 3/8 return, so the pump wasn’t under any particular stress from dead heading either.
(Not that it should matter to a rotary vane pump)
Not a single glitch after replacing it with the Holley pump.
