    i didn't buy that kit but i do have all those parts installed on my suburban. it was straight forward and took a few hours but only because i cleaned up the routing of stuff and i also replaced all the vacuum lines like you were talking about doing. as for part # for the vacuum lines i went to auto zone and got one of the silicone vacuum line kits that come with 4mm,6mm,10mm lines. they have them in red and blue and the silicon line hold up to the heat alittle better. good luck.:D

    what kit are you talking about? i bought my stuff from different dealers so as i could piece together what i wanted, i also installed a vacuum reference adjustable fuel pressure regulator and milled my tbi top and polished the bores. so let me know what kit you are asking about and I'll help all i can.:D

    the hose kit came from auto zone i don't have the part# for it but it on the shelf with the fuel lines and so forth. the regulator lets you set your wot fuel psi to like 15psi and at idle the vacuum pulls it back down to around 8psi as to not let your motor run rich at idle.

    not sure if your aware, but that kit is for 88-95 pickups. some of the parts like the ram air tube will not work. all the tbi stuff should fit tho.

    About the shifting, the spacer moved the tb up an inch. When you do this, it messes up your tv cable adjustment. You need to re adjust the tv cable in order to get the tranny shifting right. I wouldnt suggest driving it much until you get it adjusted right. An improperly adjusted tv cable can wear out the tranny in a matter of miles.:eek1: The tv cable adjusts main line pressure, and when its out of adjustment the tranny will not shift right.

    so i brought it down to my local tranny shop...and my tv cable is messed up...neither i or them could get it to disengage or get it to move out when u turn the throtle bracket to W.O.T.....so i have to either take out the spacer for good,take it out for now and have them order one..put it in monday..then put spacer back in....THEN GO BACK DOWN THERE AGAIN to have it adjusted, or just dont drive it till monday and beg my grandmother to let me borrow her car???? wat should i do guys??? if i take it out for good any one want it?

    Did your spacer come with small spacers and new bolts to raise the TV cable bracket?
    I had one on my Burb for a few years and that was what was in my kit to get the alignement back. Even then it was a pain to get it adjusted correctly and I eventually took mine out.
    I would be interested to see how well the injector spacer works out though.

    well i bought longer bolts and washers from home depot and my tv`z adjusted right....kinda hard to see a difference with injector spacer because that wasnt the only thing i did....but i got a little quicker acceleration and some more power and gained about 2mpg
