Pickup may have fallen off.

Electric or mechanical guage?

Did you tack the pickup they are known for falling off the 454s

Do the big blocks use the same style plastic collar on top of the oil pump drive that the small blocks use? I seem to recall someone making a steel replacement for them, as it wasn't unheard of for them to get brittle with age.

Yes they use the same from the factory, and they do end up in the pan, you find out when you pull the distributor and you hear that horrible thud when the drive hits the bottom of the pan, lol..

I like the Melling "Select" pumps with bolt-on pickups.

You'll find them in my engines.

So bad gauge

Time to verify if the gauge works.

I have 2 gauges 1 electric 1 mechanical if I take them out I don't get any presser out of the hole in the block
