Gas needle vibration

[JF1957]

My gas needle gauge is vibratin like the wings of a bird fly, does anybody have that kind of problem ?

Yea...its pretty natural for your gas gauge to be inconsistant.

i dont think hes talking about inconsistency. My 1999 suburban does it too, vibrates in very small increments but very fast, like a humming bird or something. Does anyone know what causes this?

looks like we are the only ones here that have the problem, ill look into it and let you know if i find a fix. You do the same, take care.

My Astro van started doing the same thing after the fuel pump assembly was replaced. It was replaced with a non OEM unit and it started it then. I don't know what caused it, wish I did...

I don't know if it's a coincidence but it's look like my fuel pump is increase is whistlement.

Try, just for the hell of it, running a 20 oz and 12 oz (32 oz total) bottle of Chevron Techron concentrate through your tank. Maybe it will help the situation. I also heard that BG 44K can help to break the crud off of sending units. Maybe these things would help. However, it's possible that this is just to fix "stuck" sending units. Probably worth a cheap try though. Remember though, if it isn't Techron Concentrate (costs like $7.99-$9.00 a bottle) or BG 44k it isn't worth buying.

i guess i should add that the fuel pump has been replaced prior to me noticing the vibration, thats probably whats causing it.

I replace the fuel filter today, just after, it seem like the noise was lower but after having refueling the tank it came loud again.

use the search function--there are lots of fuel sending unit issues with these trucks. also, i ran 2 tanks worth of that Techron Concentrate Plus stuff through my truck, and the vibration is significantly less than it used to be, but it isn't gone.

GM Fuel System Treatment PLUS

GM Fuel System Treatment PLUS, P/N 88861011 (for U.S. ACDelco®, use 88861013) (in Canada, 88861012), is now available for use in gasoline engines.

 

Added Benefits and Uses

The PLUS portion of GM Fuel System Treatment PLUS is the addition of a filmer additive that, when used regularly, can protect fuel system sending units from the corrosive effects of certain sulfur contaminants found in some of today's gasoline.

 

Sulfur contamination can disrupt electrical continuity of certain fuel sending units and lead to erratic or false fuel gauge readings. With scheduled usage, GM Fuel System Treatment PLUS protects against the effects of harmful sulfurs in gasoline.

 

The Four Benefits

Just pour in one bottle of the GM Fuel System Treatment PLUS into the fuel tank when refueling around each oil change interval:

 

• Cleans -- Sulfur corrosion from fuel gauge sending units.

 

• Prevents -- Harmful sulfur components from attacking sensitive fuel system electronics.

 

• Protects -- By coating metallic surfaces of the fuel system.

 

• Removes -- Engine deposits left from use of poor quality fuels.
