    Mike.....Here are the Fuel Rails, from a 99" to 2000" and from a 2005" to 2006"....both show what Engines/RPO Codes these rails are for....

    Chevy 1999-2000 CK1, 2, Fuel Injector Rail, (LM7/5.3T, LR4/4.8V, LQ4/6.0U)....Number #9 is the Fuel pressure Reg.

    Of course, you went above and beyond. I now have my answer. I have an L59 engine. No regulator on the rail. Damn you GM, you took away my ability to change the fuel filter and the regulator!!!:grrrrrr: Whats next? In a few years am I going to have to go to a dealer to fill it up with fuel!!
