Oil pressure gauge fluctuation - Yes, another one

[HighHP]

I checked sw8368, sw5192 noted above. NAPA carries both these part numbers. Both are switches for idiot lights, not variable for gauges.

Thanks HP… I discovered that today also.

FWIW…..In my 15 yrs of ownership I haven’t been sidelined like this in locating such a basic replacement part. Sadly, things will only get worse for the 05/06s. Fortunately the driving experience makes it all worthwhile

So now that I have driven my Ford GT about 1,000 miles since I changed my oil pump belt i have noticed that my oil pressure guage does not fluctuate anymore. Just sayin...

Exactly what does "does not fluctuate any more" mean? If the pump is turning, oil pressure must fluctuate with engine speed ....

Yeah, that doesn't make a lot of sense. The oil pump belt is ribbed, so it can't slip, unless the ribs get ripped off, which you would notice when you took it out. If your oil pressure gauge is reading differently now, it must be because of something else you did/poked while you were replacing the belt.

I just received a sender from Ford, pt #4G7Z-9D290-AB that was on a "supplier problem" back order for a while.

40 psi at idle and 75 psi at wot. All is well.
