Default LSX Questions

Im going to be using F-body accessories on front of my 5.3 engine. Will a A/C compressor from a 5.3 line up using those accessories or will I need a compressor from a F-body as well?

I read about people deleting the rear O2 sensors... Is there a reason for not taking all 4 out?

Will a driveshaft from a LS1 Camaro swap right over into my cutlass after I drop the 5.3 & 4L60E in?

The ECU/PCM need the front two for fuel trim, to keep the air/fuel ratio correct.

Not really sure.... but I would guess you need to get a F-Body one also.. else the pulley will not line up with the F-body Balancer.

My engine came out of a 2002 GMC Sierra & it has a cable driven throttle body on it. Will I be able to use that same TB if im swapping to the LS1 intake or will I need a TB made for a LS1?

Im ready to start purchasing the parts for my fuel system. I have the stock LS1 returnless type of fuel rails & I will be getting the Walbro 255 intank fuel pump & the Wix 33737 in-line fuel filter.

I need to know what size hoses to use with these parts & what type of fittings to use to connect everything?

That diagram helps a lot with what fittings I need. The only thing i am a bit confused about is the diagram shows the stock sending unit with 2 ports & mines have a third port. What do I connect to that one?

Also, what is the best fuel line to use? I was looking at the black cloth wrapped hose from Russells. I think it was rated at 350 psi. Is this a pretty good hose to use?

One is a feed, one is a return. and one is a vent. In this thread there are better pics of the sending unit andit shows how to modify the sending unit.

As far as I know that hose will work but maybe someone will correct me if I'm wrong.
