Default Vacuum Connections.

Does anybody know where to get the Vacuum connections that go on the throttle body and the FPR (or the part numbers) Mine look pretty externally cracked, and I just figured tha twith 114,000 it couldnt hurt to change those along with the rest of the vacuum hoses. Thanks in advance.

Do you mean the plastic distribution tower or the lines? The lines can be had at any atuoparts store. Take your old ones with you to get the right size. You'll need a generic size adapter for the line that goes to the FPR because it changes size.

My main concern is the 90 degree elbow that goes on the throttle body and attaches to the plastic line which then goes to the transmission. and the T connector which connects to the throttle body immediatly below the elbow. The "T" vacuum connector is in line with the fpr and the purge solenoid.

It would be my guess, and it'* just a guess, but they probablly are not that expensive from the dealer

Default update

Update: I found two of the three parts at the delarship; the three way connector and the 90 degree comming off of the throttle body and going to the transmission. the part numbers for those (for anybody who wants to know) are: " 3- way connector"- 24502852 and the "90 degree elbow" is 24503110. both parts togethor ran about 7 bucks. the third part; the elbow for the FPR was a tough one, the computor says that that part cannot be purchased seperately. but here is the catch, it doesn't come with the FPR or the plastic vacuum line the parts guy had no part number on file. so he took my vin number and called the supplier in willowrun, Mi. The man in willowrun told him that an elbew which is the same as this one is on a transmission vacuum line (not sure what type of tranni) and that I can buy the line and simply remove the elbow from it. The vacuum line ran twelve bucks. Im not trying to sound cheap but it doesn't seem worth it to pay twelve bucks for a part that I only need a tiny elbow from! especially when the other two bigger connectors combined cost half that much. Has anybody had any luck finding a similar part at an auto parts store, or fabbing something that works? by the way the part number for that transmission vacuum line is 24506302
New update: the part number for the transmission line 24506302 is in fact the necessary part it comes with the FPR elbow, the 3 way connector from the throttle body (24502852), and the two pieces of 13mm hose that connect the vacuum modulator orfice to the plastic line. it also includes the whole plastic line but i dont know if the line will work because in order for him to find the part I had him search the schematic for a 97 grand prix...wtf. Apparently the 95 bonneville schematic is wrong. The funny thing is that the line is different on the 97 grand prix and 96 bonneville. But is the same on the 95 bonneville and 97 grand prix.
