I try never to think about that AJ lol. but I will look into it. there are way cheaper ways to do it than how I did it, for instance you can just buy rubber efi fuel line and use double hose clamps. that is what I did for my yj jeep when I did the mpfi conversion. but I like the AN lines. as far as the O2 sensor. the sensor and bung as well as a plug came in the basic kit. the kit can be purchased with the fuel pump and lines but most of the people who use that kit say it is not enough fuel line.
I took the car to my local exhaust shop guy and he welded in the sensor bung and put the plug in it. (you should never drive with the sensor in but not plugged in apparently) he did that before I started anything. he charged me 40 dollars which I thought was very reasonable.

ok well AJ thanks alot for that lol I went back and looked at what it cost me. keep in mind I had all the fittings to do the return line so that would add to the cost, and I had the adel clamps and grommetts that I needed so those things would need to be figured in. but again it could be done a lot cheaper than this if you go with an inline pump and regular efi fuel lines.
having said that here is my list with hyperlinks and costs.
Fuel tank 225
Fuel pump kit 210

the o2 sensor bung was welded in for 40 dollars at my local exhaust shop.
I also had a lot of various parts that I did not need to buy like the powerbraid wrap. All the terminals for the electrical connectors. And the 3/8 to 5/16 reducers for the fuel pump.
For a total of about $ 3514.50
ok. I hope that helps
