Throttle Body Hose Confusion


Recommended Posts

Cleaned throttle body, trying to put back vacuum hoses, got confused as to where they "plug in." Does the "check valve" plug directly into the throttle body? Does any body have a diagram of the hose configuration? Which side of valve plugs into tubing/or throttle body. I thing one or more of these vacuum hoses were not plugged in prior to me buying the car

Thanks for any help that you can give

Does one of the hard plastic lines plug directly into female orifice on the throttle body? Seems to me that someone before me, had the check valve plugged directly into the throttle body...which is incorrect?

Thanks for your help.

Check valve plugs directly into the nipple on the rubber sleeve for the cross plenum on the right hand side when standing at the back facing the front of the car, black side to intake, all other vacuum lines except the vacuum for the FPR feed off of the rubber 'T'. The line for the FPR goes to the nipple on the other side of the crossplenum directly.

I think that cleared things up...black side of check valve plugs directly into sleeve on throttle body. Other end of check valve plugs into "T" where the hard plastic vacuum hoses connect....

Thanks much for the help

The vacuum hose plugs into rubber sleeve on the passenger side as shown in the picture below.

Now I think I'm confused....previous thread indicated(from my understanding) that the check valve plugged directly into rubber sleeve on the throttle body. Your pic shows vacuum hose plugged into sleeve. If one end of check valve plugs into Y connector, where does the other end of check valve plug into? There appears to be a cannister of some sort, that has another Y connector at its base..does the check valve plug in there? Thanks for your help...any website have a schematic of the vacuum hose setup?...thanks for all your help. NVYmed

This might help solve your problem. The hose from the circled check valve goes to ruuber sleeve on the passenger side.
