ran my truck by the dealership to have a code ran today. they tell me that the fuel sending unit has a buildup of sulfur on it, and to try running a few bottles of techron through it. i use techron with every tank, so it looks like i may have to have it replaced. has anyone had exp. getting this done, i.e. price, time in the shop, etc?

 

What do you have and what is the code?

 

Wonder how they determined that, or is it from experience?
Any additive would need to have ingredence that attacks the sulfur, so select carefully.
After it is dissolved, it is still in the fuel.
If found to be the problem, you need to consider getting fuel from another source if you can prove were it came from and it may be legallly actionable.
Down in southern states, this has already been found and addressed in a legal manner, a couple years ago.
I believe it is now law that fuel has to be low sulfur to run in the new trucks.

 

they didnt tell me the code, but told me that the code indicated fuel sending unit error. based on experience with other trucks along with info from ford, the dealer believed that sulfur was the prob. i only use chevron, but since katrina, evidently this has been a prob. with fuels down here.

 

btw torkum to answer your question, ive got an 04 fx4 with 5.4

 

There is a tsb out there relating to this issue, the first step is to add the Techron, and then see if it goes away or not, then they will have to put a sending unit in it... Or thats the way i have to do em, more hoops from the Ford motor corporation.......

 

well, i added 32oz of techron to 25 gals tonight, and will see what happens.

 

you put in techron with every fill up???. is it possible to use to much of that stuff??. i put in a bottle every oil change and never had a problem.

 

with every fill up. as standard maintenance i use a 12oz bottle with every fillup.
