First off happy birthday young man I have a 1990 E150 van power steering pump was out replaced it did everything properly to bleed it elevated it pump still didn't work but it for an hour use a vacuum system on it also to bleed it still not working thought it might be the pump put in another new pump exact same process still not working. So what's up with that also FYI I refer you to a lot of people very professional thank you very much for that. Kevin Ellis

realize I ONLY use brand new ps pumps, rebuilts often stink, especially on fords. I would start there
