So I've read many threads on the issues our cars have with the tank not filling up like it's supposed to amd after doing the TSB for the shutter valve and replacing both fuep level sending units the gauge still won't reach the 3/4 mark though it did take 15 gallons last time I filled it up (just above E). So I've given up. And I'm in need of an expert. Is there some kind of calibration I needed to do to the new sending units? Is there a different problem? I just don't know. Any help would be much appreciated.

mine was doing this too, luckily car was still under warranty and they replaced the sensors, I still dont really trust it though, lol! I just fill up every 200-220 miles, just reset the trip every fill up, lol!

There is a easy way to do this, the sensors are behind the seats, behind the subwoofer, just remove and clean with a Q-Tip, heard it works pretty good!

I tried the q-tip method a couple weeks ago. The resistor boards were fairly clean and it didn't do squat. Fuel gauge is still wrong.

I said screw it, I've lived without a fuel gauge for 6 years now, I don't need one now....

I've seen people mention they had a faulty gauge in the cluster, but nothing concrete.

You should get around the 400 mile tank range depending on your driving conditions, if you've already replaced the two gauges in the tank, it's probably going to be the dash gauge.

If youre getting 400mi per tank on anything other than long highway drives going 65 the entire time...let us know your secret.

i do 50/50 highway city, my tank is usually 22 to 24 mpg on the readout. If you're in traffic or stopped at lights a lot, that kills it.

If i go on a long long highway drive, i'll get 27 or so.

I can easily get 400 per tank daily driving......

All highway I can go 450-500 no problem.
