I'm in southern Illinois....does anyone know of a experienced mechanic who can install a new IP on my 1990 E350?
First Welcome to OB, if we can't get ya going no $$$ mechanic can! Take a look at the various sections FAQ, Tech Articles and HALL of SHAME, so you don't spend money on bad vendors. There is an IP article too so that would be of great help for you. Don't be overwhelmed!
So long as you have some basic hand tools, and you can use them we can help you and guide you.
I will be listing the van in the classifieds....I'm just not able to do the pump replacement.....thanks for all your help.
We can certainly assist you via thorough instructions and guidance, there is a member who's offered you his # and help and I'd suggest you begin with talking with him. The overall procedure is not that complicated, however it's more difficult due to nature of the van and limited access.
If you can swap spark plugs, or change oil, or tyres, or as I say, toilet paper rolls, then you can swap an IP! It is not doing anything more difficult than swapping parts. You are not doing anything special just parts swapping plain and simple; no critical machining, no critical measurements just undo bolts and remove one part and then install the replacement!
However if your engine is locked up that is NOT the IP but something much more involved and would require some diagnosis again something we can help with.
Do not be intimidated by something as simple as a toilet paper roll change with many steps

because that's all it is.Ag
