I have a middle plenium small hose with a bolt in it ... one after that is brake servo ... one before it goes to under idle Allen on plenium throat ... I then have a fuel regulated with a hose on it going nowhere ...

Sorry ... reason being awfull starter if it starts at all and runs like a bag of sh...te

Might be a good idea to post a photo of your engine indicating the hoses your having a problem with.
A fuel regulated with a hose on it going nowhere is a problem.
All I can do to help u is let u have this scan from my Haynes manual for the 3.5RR.
