Ken,
I don't remember the year of the van but you may want to try installing the metal filter after the pump. The problem may also be bad fuel gumming up the injectors. Drain and refill the tank and use the later filter along with another injector set.

Thanks so much to everyone who had ideas about what was wrong with the Vanagon I was working on in Belize. After testing several things I decided to pull the injectors to watch them spray. Instead of a nice cone shaped spray pattern I was seeing a little squirt like from a squirt gun. The fuel pressure was good, and I even did a volume test which also seemed good. We had another set of injectors handy so I swapped them in and voila! The van started and ran well. I was so happy and it was still morning so I thought we were going to be able to get back on the road with the van and do some sight seeing. The customer had complained about the van running good, and then starting to run bad after a bit of running and then not wanting to restart when hot. I thought this was probably due to the bad wiring harness which has been replaced with a new one but I wanted to be sure. So we let the van run and it sat there and idled for about 20 mins. Initially it had good power and everything. However after about 20 mins of just idling the engine started to not respond well to the throttle and then it just died and wouldn't restart again! It was acting exactly the same way it had when I first got there. I pulled the injectors again and they were spraying in the exact same way as the old ones. Just peeing, not really spraying at all. I decided to replace the fuel pump. when I pulled the line going to the pump, about 3 tablespoons of rust spilled out onto my hand. I had found the problem. I blew back into the gas tank, hooked the line back up, and the van started right up, ran for about a minute or two and then died again and wouldn't restart. I think there is so much rust inside the gas tank that it just keeps getting sucked up into the system and bogging things down. So now I have to get a new fuel tank and parts sent down here. I am going to try to get in touch with the customer today and see what he wants to do. If we can get this done, perhaps the van will be back on the road and running well. I tested through the entire fuel injection system with a meter and all of the grounds and sensor tested fine so I am pretty sure that everything is good and that the gas tank is the problem.
Just wanted to let you guys know what I found. One suggestion is to run the van off of a new 5 gallon plastic gas tank. However I am not sure how you could do this without doing some serious mods (drilling holes and running really long fuel lines). If anyone has any ideas in this area, something that you have done before, please let me know.
Hope you are having a great day!
