weber install ?

i have a 87 b2000 i know how to install the weber but not sure what all i can delete as in vac lines an wiring i dont need?

The only vacuum line you will need is the vacuum advance line from the distributor.The rest of this can go in the trash.

What bout o2 wire harness an ecu?

ecu can be removed completely if you want i have pictures of removing mine.

You don't need those. I still have the O2 sensor installed in my exhaust manifold with my Weber, this way I don't have to worry about ruing the threads in the manifold or plugging it up again, I let the O2 sensor be the seal. It's just not plugged in. And my ECU is still in place, just the connectors on the passenger firewall are all taped up.

Are you guys running the manual choke or electric?

did you guys trash can the charcoal canister too?

I kept the charcoal canister with mine. I made an EGR block off plate too. I also added a stronger return spring. See my list of other Weber install hints, do a search here.
