For the last few weeks, I have noticed that I have gotten excellent fuel mileage. One week I was at 325 at half a tank, then I was at 385 the next tank. Now, I am at 425 at half a tank. This doesn't seem right. I also noticed that when I filled up last at 1/8th of a tank, I topped off at 32.5 gallons on a 35 gallon tank. I use PS in my fuel and Fleetguard fuel fiters, but I don't think this is normal. Could it be the float, or could the fuel sender unit be going out? The gauge moves, it just seems REAL slow.

 

mine is the same way! i hate it....1/2 on gauge is really more like 1/4! always been like that for me though

The next thing will be, you will run out of fuel at 1/2 of a tank on the gauge! I would not trust it. Those senders are not the most reliable of all electrical devices in the world.

Mine did the same. Get a new float and sending unit and replace it. I lifted the bed about a foot or so and installed it in about 15 minutes.

 

Have you filled up at a truck stop and used the high volume pump? I did that and it bent my float arm. I ended up replacing the complete unit while I had it apart.

I have filled up at Wal-Mart and some truck stops and they both have pretty stout pumps. Which is better to go at it: lifting the bed or dropping the tank and how much do these run at?

 

Inless you have ran your tank pretty dry it would be easier to lift the bed up. Be sure and secure it well before working under it. I can't remember the cost of the sending unit but it didn't seem to be to pricey through Napa.

If you plan on dropping the tank just a few gallons of fuel can make that tank shift pretty quick, be careful if you go that route.

How hard it is to lift the bed?

Easy to lift the bed. Just take out the bed bolts and lift or jack it up. I just loosened the 2 towards the rear and left them in place. Then just lifted the front of the bed about a foot
