OK men, here's a real high tech question. you'll have to dig deep into your brain, or GM library. Is the factory mech. lift pump (as delivered and installed), painted eng color (red), or just left natural? I'm replacing mine, and the more factory it looks to me, the better I like it. Not a big deal, just don't want to have it keeping me up at nite, tossing and turning, cause it's not correct. (If you saw what my truck looks like right now, you'ld be rolling your eyes even more).
