autometer gauge install help

[DanaliHD]

I just got an autometer air/fuel gauge and a fuel pressure gauge to mount in my 3 pod pillar along with my boost gauge. The instructions are sort of vague.

Air/fuel: which o2 sensor do i need to tap into?

fuel pressure: it says "install the 1/8" NPT pressure sender into the fuel system... do not mount sender directly on fuel rail..." Where do I mount it?

Is the FP electric? I have the electric FP and mounted it directly to the rail with no problems.

The fuel rail is a 4AN sized fitting. You'll need to find a fitting that is female 4AN/female NTP. I got mine from Earls and unfortunately, it wasn't as easy as getting one fitting. I had to get several fittings to get the right setup. I ended up with a female 4AN/male NTP fitting and a female NTP/female NTP fitting to get the right combo.

BTW, with the AN fittings, you don't use thread sealer.

well for your Fuel PSI to be correct since you are supercharged you need to install it on to the new whipple intake. Near the top where your new auxiliary fuel lines are there is a hex nut you need to remove and install it there. Your Air/Fuel ratio i dont think it matters which 02 sensor you put it on. Both will for the most part give you the same reading.

thanks for the info guys

I took a look at the hex nut on top of the aux injectors and it is much larger than the adapter that came with the fuel gauge. Is there some kind of adapter I can buy to make it fit?

Ok, how do I bleed the fuel line so I don't spill fuel all over the place when I tap into the fuel line?

Ya just go to AutoZone and take your autometer adapter they give you and get one that fits it and then gets bigger to fit the opening. Thats what i had to do. As for bleeding it, i just grabbed a rag or two and wrapped them around the hex nut and removed it.
