Having said that, I thought I would start yet another thread with this question for those more technically knowledgable people to provide the information needed to mod in an external pump.
First, what sort of external pump would do the job? That I would figure is the place to start. What sort of flow, what sort of pressure? Links to possible pumps available online that would meet the specs. needed to provide sufficient fuel for the 4.3 at the least if not for a V8.
Second, what issues as to the overall fuel system need to be taken into account and suggestions on how to deal with them. I have little, ok virtually none at all, experience with the fuel system and am not even sure on the way it functions on a stock vehicle, and I would assume there are things that need to be taken into account to retrofit an external pump into the existing system without major modifications of the entire system.
Third, we need the guinea pig to try it. I keep on the lookout for a used van in about the same years as mine for a good price (sort of like ihatemybike's grumpy) that I can try things out on, but currently funds are low and I don't have room to store another vehicle. If I find one, that won't stop me, but I still have no idea where i would park it.
Answers to the questions above, and suggestions of things I am not thinking of would be appreciated. I am hoping that in the end this will result in a viable mod installing an external pump. I should have asked for the old pump when it was replaced under warranty, at least then I would be able to see how it is designed to function. Alas, I did not.
