I Think My Fuel Gauge Is On Crack

[DV2000NJ]

I had that going on for 2 years with my '00 Sierra. Then one day the fuel pump died and fixed that problem!

I say mines on crack also.



But that's just my excuse for getting 6-10 mpg since I upgraded tires/wheels.

Sounds like it's time for a re-gear!

Diffs are 3.8:1 and tranny is: 3.57, 2.20, 1.51, 1.00, 0.80:1. Reverse: 4.10:1, transfer case is:1.00:1 (hi), 2.69:1 (lo)

Do you think I need to regear???

It's the sending unit. Had the same deal on my '99 GMC. I just lived with it until I traded it in. It's in the fuel tank so you'd have to either drop the tank or remove the bed to access it. If you do it yourself most people recommend replacing the fuel pump as well while your there depending on what your mileage is.

would it be the same on 90's my gas gauge is off a lot. the beds off so now would be the best time to replace it if so

Yes

4.10s would help, or 4.56s, whatever they make for those diffs...

This truck is mainly used offroad. Do you think this change would affect the capabilities?

You would benefit from it most likely when offroad.

Definitely!

You'll be able to spin the tires easier when buried in the deep mud, and hill climbs and decents will be easier

But taking it that low would kill what little bit of gas mileage I do get without making up for that much difference offroad.

Your engine will work less to turn the heavier and larger tires.
