Fuel Pump Regulator

[Newfieboy58]

I have been having a ticking/tapping engine noise. No dash lights. Rough idle. Runs not so well.

Concerned it may be a lifter issue. Service visit has been scheduled.

Anyway, had a guy contact me on YouTube saying it sounds like it could be the fuel pressure regulator....says GM addressed this regarding 2014-2019 models. I have a 19 TB.

Anyone have any experience with this?

I went to autozone last night.....the part has to be ordered and is $250 - $350. Not cheap.

Just got my truck back from the dealer today the ticking sound is gone from engine and sounds like the first day I bought it so it was what they diagnosed afuel regulator

I hope they are right and you get your truck back in working order sooner rather than later. Let us know how it goes.

Got truck back today all good now no ticking noise so it was the fuel regulator this is the 3.0 dduramax diesel
