Loss of Power - New Fuel Tank?
Moderator: If there is a better topic forum for this please move it, thank you.
OK, I have a 2002 F350 PSD with 108000 miles. I'm the original owner.
Last month it developed an intermittent loss of power. It was more likely to happen when the truck was under load (pulling a 5th wheel RV). The best way to explain it was like I had gotten a tankful of bad diesel. I pretty much ran that tank out, filled up, added a can of 'SeaFoam' and changed the fuel filter.
Didn't solve the problem. Since that time I put about 2500 miles on the truck and have had the problem several times since then. I have also replaced the CPS and still not the solution.
Today I took the truck to the dealer. He checked codes and found a 'low fuel pressure' code. He checked the fuel pump, oil pump, etc and all checked OK.
His diagnosis is related to the low-sulphur diesel fuel now in use. He says there are chemicals in that fuel which can attack the lining of the fuel tank causing it to flake off. That debris then clogs the in-tank filters to the fuel pump. The only way to be sure is to drop the tank and look inside. He said he's seen this before in older diesels but this 2002 is the 'newest' one he's seen which looks to have this problem.
If there is debris in the tank he sees 2 options:
1. clean it out the best possible and fix the problem temporarily or
2. replace the fule tank ($1200 for the tank) plus 400 labor. He said the new fuel tanks have a different lining which will not flake off.
So I was looking for any experience anyone may have with this issue. Have you heard about this being a possibility? Any suggestions about other possible causes of the problem.
