Oxygen sensor with Weber carb

hmm.. well on a cold start after warming up I can open the throttle all the way and it will "hesitate". Its not really the tuning, it just that you've introduced a crap load of gas instantly and the air has to catch up with the vacuum.

If you open the throttle a little bit then hit it to the floor, you will notice a better response.

I don't understand how you will need a fuel regulator for your weber, prwmetalman. You should have a mech. pump, not electric. Unless you got an aftermarket one?

Electric pumps are for FI not carb. Anyways, if your float floods out, you will need a regulator. I don't have one on a mech. pump and 'am doing fine...

Yes, from the factory, my truck has an electric fuel pump in the gas tank and the opening for a mechanical pump has a factory block off plate.

...weird!

Well, nonetheless, you will need a fuel regulator, then.

If i was to weld a universal bung into my header collector, what o2 sensor would i buy to use with an aftermarket gauge? Has anybody done this?
