Fittings
What fittings did you use to connect the existing fuel line to the sensor/analyzer? It looks like the analyzer has the steel quick connect fittings, and I'm assuming the stock fuel line is that Teflon tubing... I ordered a similar kit from MAPerformance so I'm thinking about installing it tomorrow and I have a couple fittings but I'm just not sure the best route

i dont think that would work. Since fuel has to constantly run through the sensor to keep telling you what the e content is. If it was off where fifth injector taps into, and go into the sensor and come to a dead end, u would only get a reading of that fuel that is in the sensor, and it would not change cause the fuel cant flow anywhere so it just sits there

gotta bring this thread back from the dead since i plan on doing this to mine right now. question is, is the line the op used for the sensor the same line tom is talking about in his post about it not working right or is it another? seems like the op got it working nicely with the line he used.

I just spliced mine into the fuel line right in front of the drivers door. Never an issue, other then the fact it sometimes wont work when it gets really cold. I used the Innovate gauge. Great gauge, but horrible customer service if you have any questions or issues

I understand the ease of looking at the gauge and seeing the E content of what is currently flowing through. What I don't understand why we really need this. If your running E47, don't you need to test the e85 before before you add the 93 too it make sure you are getting the proper mix? If you are testing it and mixing it properly doesn't that eliminate the need for the gauge? I feel like even if you are using full e85 it's probably best to test it before taking the risk and pumping a full tank of it straight in to the tank and risking it not being right. Now if we had some type of option of adding a flex fuel sensor that could adjust our tune in real time like a flex fuel vehicle, to the current blend of E mix, I could see where this would be useful.....

so my thought and reasoning for this is since i switch from 93 to E alot i like to know when one fuel has burned off and vice versa. since you never really completely empty the tank (without physically emptying it of course) theres always some left over fuel in the tank and lines and for me this sensor is just a way of letting me know when the old fuel has burned off and the proper fuel is finally flowing through. that way i stay off of it till its ready. if that makes any sense.

To me its just a lot easier to look at the gauge then to bust out the test tube. ratio's of 93/E85 to reach your target ratio. I got good at it towards the end but it was still precision guesswork. A friend of mine brought to my attention one time when we were testing at the pump as I was shaking the tube waiting for it to settle, he said "You do realize we look like we are doing a drug deal, right?"

I haven't used e47, so I don't really know. I just thought you would want to be more precise, then "precision guesswork." I mean it does seem like a PITA to test each time to, pull out a test kit, do the math, and go through the process. Is not that big of deal? Say you don't test the E and it turns out to be E-70 instead of E-85, and you fill 5 gallons e-70 and 5 gallons 93, yeah you see it on gauge, do you just add more E until it read right? Is that not like playing russian roulette with your engine? E content not being high enough would leave the lean correct? or is it really not that big of a deal?

E47 is a good blend. More power than pump and you still get halfway decent gas mileage. If you daily your car on actual e85, just expect to fill your tank every couple days. It turns into a pain. I know, which is why I dont do it haha.

anyone know the part number for the fuel feed line the op used for the sensor? i think its 22912576 but everywhere i look it says "it doesnt fit cobalt"
looks just like it though but i wanna make sure

Some light googling says that GM uses 3/8 for feeds and 5/16 for returns.
