So trying to pass smog I found this strange piece

Actually the part number I quoted is for around the 2004 MY and prior, from what I can tell.

I’m trying to get him to join the forums

Agreed.

Too bad we can't find those FPR vacuum hoses for the Flex Fuel engines (NOS or aftermarket). Haven't seen any used ones in the salvage yards, either. GM 17113699, discontinued.

I was hoping to pick one of these up as a spare, but then discovered it’s not for the L59, rather the LM7 only.

Yes, the difference -- from what I can tell -- is that the L59 fuel pressure regulator needs a 90° connection on the hose. The non-Flex FPR port points straight up already. I'm sure there's a workaround, to be found when needed.

If I ever score any at the Upull I'll be sure to let you know!

Thank you Steve.
