Hey all, quick dumb question about the plenum gasket that goes between the upper and lower parts of the v6 intake plenum: if I take off the top part of the plenum (to access fuel rail for pressure testing) and then bolt it back on, will I need to replace the gaskets before running the engine, or can they be reused? I swear I read somewhere you had to replace them every time you pulled the upper plenum but I can’t find it anywhere. I have new gaskets already on the way but they’re a few days out and I want to check the fuel pressure and injectors asap.

If you look closely, you'll find that to do the pressure test, the upper plenum shouldn't need to come off to access the port on the fuel rail. At least I never have had to take it off on my 89, and I have checked the fuel pressure several times over the years

That’s what I get for posting at work when I’m not around the car! Easy as pie to get to. Thank you!
