Drain/plug on VE pump?

490 Views 9 Replies 4 Participants Last post by  Blackduck59
Trying to figure out if I’m missing a plug on the bottom of my Bosch VE pump on my pickup. There’s a threaded hole that looks like it possibly should have a plug or something? Threads look clean… trying to figure out if that’s where I have a leak coming from up front.
The hole is slightly back from the timing device and a little closer to the block. After looking at a diagram possibly this isn’t part of the pump even?

That is a blind thread and doesn't have a cap or run into the pump. I'm going to guess that the block off plate on the back side of the IP...directly across from your KSB on the leaking. The two bolts tend to loosen over time and then the fuel can slip past the O-ring. You can try and tighten them up but usually there is not enough room to get a wrench on them back there...even if you do the chance are the O-ring is toast and there is no way to change that without removing the IP.
