Fuel Injectors Help..
Which fuel injectors does my 1999 GMC Yukon Denali with 5.7 / engine code R uses, 5mm or 6.5mm?
Since it is my only vehicle, I simply cannot removed upper intake and check the color coded or size on injector and then put everything back together.
FYI..I won't be using "poppet valve" spider assembly, I will be converting to MPFI set up.

I am having to replace my injectors also, due to the pressure regulator leaking. the new upgrade kit available through gm, eliminates the "poppet style" and is replaced with mini injectors in its place. the kit retails at dealer for 600+ however, i called my dealer who usually gives me pretty good discounts and they will sell it to me for 480. Even better, I found a brand new set from a dealer in florida on ebay for 365! you might want to look into that.
