    Just let your truck idle and start unplugging lines one by one. If the idle drops, you need it. If it dont drop then plug the line. Thats how i did my truck.

    that method is silly. more then half the vac switches work only at specific vac pressure, so something with no reaction at idle could have negative performance at rev. makes me wonder if your secondary's open.

    i say buy a weber, hook it up. ive never met a stock carb that liked to be toyed with, and you can tune the $hit out of a weber.


    block off anything that isnt used.


    you end up with a carb and 4 vac lines or less. my wagon and celica only have 1 vac line running to the brake booster every thing else is gone. :nana:

    I just removed the belt, capped the hose and removed the pump. I have had no problems and I am now about 20% more awesome. Hope this helps.

    that pump is BS and wont really affect the way the motor runs anyway.


    in a effort to have cleaner tail pipe emissions, that pump is there to pump fresh oxygen into the exhaust, essentially watering down the emissions. still the same emissions but the ppm is lower thanks to the extra O2 :doah:

    ^^ Thats good reading. When I did my rebuild I threw on a webber, (dont get one off ebay there fake) and make all block off plates for my exhaust, rear cylinder head, and intake manifold etc.

    But When my engine was still Stock with all the lines on it. I pulled everything off except Vac. Advance, and PCV. I had no troubles running, but the engine itself was worn the hell out. Just went in and pulled them. At the point it was at nothing could have made it worse.

    If your weber says maid in Spain there real webers just inferior standards and pour casting and metals used . Magneti the parent company of weber of Italy stopped production do to poor sales and moved there production to Spain were quality and materials went down hill...along with assembly .if u happen to come across a old weber I'd snatch it up . It will have a build date and product of Italy stamped on it I'm using a Spain weber 34/34 and will swap to a holly 350cfm do to constant issues
