Injection Pump Test Bench: One Heck Of A Piece Of Equipment!

On the way back from Lamborghini Monday, I got to swing by Seattle Injector to drop off my diesel Escort’s injection pump for testing and possible rebuild. There, I got my first look at an injection pump test bench, which runs the pump at various RPMs, checks for leaks, and measures the volume of liquid coming out each of the ports. It looks to be a pretty burly machine, and I’m kind of on pins and needles in anticipation of the verdict: injection pump work isn’t cheap, my particular pump is obsolete, and in contrast to gas engines’ carburetors, taking one apart oneself isn’t something that’s generally recommended (even experienced shops will rarely touch them). I guess we’ll see how it turns out. See more pumps below the jump!
