Okay, so I’ve been running two of these Macnaught pumps on my service truck, and guess what? I’m ordering a third. These things are troopers—living outside 24/7, pumping 15w-40 even at 15°F like it’s nothing. Cold weather? No biggie.

Pro tip: Get a preset gun if you’re moving large amounts. Saves you from standing there like a statue. Also, 5w-30 flows crazy fast, no matter the temp. The specs? 3/4" NPT fluid outlet, 1" NPT fluid inlet, and a 1/4" NPT air inlet. Easy setup—just grab some 1" iron pipe or PVC with an NPT adapter, cut to size, and you’re golden.

WARNING: Don’t go Hulk on the fluid outlet fitting. I learned the hard way—cracked the pump. Pipe tape + snug = happy pump. Oh, and the noise? It quacks. Like, legit duck sounds. Makes oil changes way more entertaining.

Some folks had failures (RIP), but mine are holding up. Plus, Australian-made beats the Chinese junk I’ve dealt with before. Worth the gamble if you ask me.
