I use a VDO pressure sender as my fuel pressure sender. I have it permanently mounted in the engine compartment attached to the fuel pressure testing tap. It works reliably for me. I like it because I can at least rule out low fuel pressure as a source of the numerous problems that affect drivability of my Westy. ;-) FYI, I was originally using a cheap JC Whitney oil pressure gauge and it died on me after a few weeks. :-(( Worse, it was giving me incorrect readings. :-(((( which made debugging the fuel system much more difficult. I identified the problem by running a mechanical gauge in parallel to the electronic sender and running repeated tests. The VDO pressure sender seems to be of a much higher quality. If you're going to run more wires under the van, you might want to consider running a pre-built wiring loom, like the type the sell for trailer lights. That way, you can run four wires at once at the wires will be of different colors. What sender are you using to read your vacuum? Do they sell a VDO sender for that? I'm intrigued. If you start putting different senders onto different gauges just be aware that there are different types of senders. I think that the VDO pressure senders are 0-180 ohms and that needs to match up to the proper gauge. Let me know about the vacuum gauge. I've got two spare wires running from my engine compartment to my dash that I could tap into. Also, does this really help with isolating vacuum leaks? I always suspect I have vacuum leaks, but never went through the hassle of attaching a vacuum gauge. I've got a mechanical vacuum gauge tucked away someplace in the garage. -- Craig
