My 2005 Sprinter is dripping diesel from the front passenger side (USA passenger side) and I did some research and it looks like it's the high pressure fuel pump.
It started with a strong odour about a month ago, but I couldn't see any drips or evidence of anything wrong. In fact, my mileage increased from about 18 MPG to about 19 MPG, so I wasn't worried (but the hot weather finally kicked off here in Florida, and that could just be me not running the AC).
So, we finally got some cold mornings and I noticed a large 1ft diameter circle puddle under my van one morning after making a short run to the hardware store. I figured it was okay to drive home and by the time I got home the drip had stopped.
But the same problem has happened every morning since.
I popped the hood and see diesel and bubbles coming from the top of the pump now and then when it's running.
So, I went to this thread for pictures, but none are found:

I saw a tech alert about these:

So I guess mine is the 647 high pump.
I emailed Dr. A for advice:
Can somebody please confirm that all I need to do is remove the 3 bolts and then I'll just have it in hand enough to take to my workbench and re-tighten? Or will I need to remove more than 3 bolts and need to replace clamps? And will the fan need to be removed? And if so, how is that done?
Thanks in advance.

I emailed Dr. A for advice:
This was the reply:Do you have a step-by-step somewhere?
What tools are needed (for not only the pump, but whatever may be in the way)?
What new parts are needed? (I assume hose clamps are best used only once, etc.)
Do you have a service where I can order a rebuilt from you and then ship this old one back? I cannot really afford to take this van off the road for more than a few hours as it is a service vehicle.
Thanks for any help you can get to me.
Okay, so I guess it's much easier than what I figured. But I pop open the hood, and 1 bolt is pretty much under the fan. I see that a fuel line may need to be removed, And I see 2 hoses clamped to this. (Or maybe I'm looking at the wrong part.)You can do this yourself. 3 small, male E10 Torx bolts hold the pump onto the engine.
The loose countersunk bolts causing your leak are on the backside and not accessible until you remove the pump, lay in upside down on your workbench, retighten, reinstall and your ready to go. Andy
