Respectfully, I have never been afraid to tell anyone why my truck was not warrantied...The official reason for the warranty denial was "water in fuel'.
I asked you several times, this is the first direct answer I have gotten.
I admire your persistence in your goals.
But I also think the direct , whole story serves you better.
The failure rate of these pumps is very low.
The 3 members, on this site, who have lost pumps, were water related.
In your case, you say the first dealer mis-diagnosed yours as water in the fuel.
Most of us would agree with you that the dealer personal are woefully under trained.
There are good ones, but they seem to be somewhat elusive.
You had your truck moved to a dealer you trusted, but it seems your fate had been sealed.
You say your dealer found no evidence of water contamination.
That is a shame.
Your description of how your truck acted when it shut down is very similar to the folks who have had water issues.
And, unfortunately, you had modified your fuel system.
I hope you have better luck in your future.
IIRC you swapped to a GM/Chevy product.
How is that treating you? Care to compare them to the Ford for us?
