Seafoam a fix for the dirty fuel sensor?

Kind of as the title states.

I have the "stuck at 1/4 tank" fuel gauge issue. If the same holds true for me, I have a dirty fuel sensor in the tank.

Has anyone tried Seafoam in the fuel tank to try and fix the sensor issue? The theory adds up, as the Seafoam is meant to clean off carbon deposits in the systems you use it in.

Just curious, I don't want pulling the bed to acess the tank being option #1.

Many thanks!

 

I doubt you have a dirty fuel sensor/sending unit since gasoline is a pretty effective solvent. The carbon deposits Seafoam is meant to clean are in your combustion chamber, not your fuel tank. Give this a try, hopefully this will do the trick.

I had this issue in a Ford Freestyle and I read to use Chevron Techron Fuel Treatment. It worked and the issue has not returned. Good Luck.

 

Another member had this problem after off roading. He banged on the tank and fixed it. True story.

 

Elk Hunter drove his off a cliff. Fixed it. Tru Story......

 

Never had this issue but I use Amsoil P.I. every oil change. I use it in everything. I'm not affiliated...May be worth a try for you?

I put it in and beat the truck for a whole tank full....meaning full throttle starts. Random full throttle times, etc...

 

Haha!

Gave the tank a good kick, that didn't work. I am going to try and take it off road a little today, see if that shakes it up a bit.
Possibly an additive...

it doesn't bother me too much, I will try a few recommendations here before tearing into the tank.

 

The cleaning agent in Seafoam is naphtha, commonly sold as white gas for Coleman stoves. You can get a gallon of it pretty cheap at the hardware store or anyplace you find camping supplies (Walmart).

Add few ounces of that and a dash of TC-W3 2 stroke oil and you have a good fuel system cleaner/lubricant.

 

Sea Foam is not just for carbon deposits! It's also to get rid of gum and varnish from fuel and fuel-burning. I am not a mechanic, it's just what they say on their website, and since I do some work for them I hear it all the time. My 2c recommendation is to use Sea Foam High Mileage -- seems a little "stronger" to me, but then again I only drive higher-mileage stuff!

 

Double up the recommended dose of Sea Foam in a couple of tanks of high-test gasoline of your favorite brand...Chevron and Shell both have high-test and advertise their clean qualities.
If that doesn't work, loosen the bed bolts and raise the bed and service the in-tank fuel level sender. Did this years ago on a full-sized F150 with dual tanks under the bed and two fuel pumps with bad return line shutoffs...you could fill the front tank, take off down the road, look in the rearview mirror and see gas dripping/oozing out of the rear tank filler neck because the return line valve was faulty. Went to my fav shop and paid them $10 to break the bed bolts loose with their air impact...drove it home, pulled the bolts and disconnected the lights and tank filler hoses and pushed the bed back to replace the front pump. Pushed the bed back forward, jacked it up from one side and replaced the rear pump. Took all of about 3 hours in the driveway...just me, myself and I.
Can't imagine getting to a Tundra tank would be more difficult...or you could just drop the tank.
