My fuel tank recall alternative :)
So I, too, experienced a gas smell and small puddling in the passenger side fuel hat. Since I'm running a pretty heavy fuel system (twin 340LPH pumps, ID1000 injectors) to support higher than average power, I also experienced something additional... melting of the bulkhead connector within the fuel hat.
I've seen pictures recently where Denroll also showed signs of this failure. This is alarming to say the least... it shows the factory system is clearly not up to the task with respect to any pump amperage higher than stock. I wonder how many stock pump modded guys are starting to experience the same. I didn't want to throw another stock assembly in there and wait for a re-occurrence so I took a different approach.
The new bulkhead connector is rated for 40 amps, over double what the stock terminals are rated for according to my calculations. No leaks... ever. Fits like stock, tighter tolerances on everything obviously with the billet aluminum structure. I've been running it for a week so far with no problems and harness temperature is reduced (subjective, by touch).
Just showing off. Anyone can think outside of the box, just put the pen to paper and get the ball rolling on your own projects.

Looks awesome! And WOW at your melted plug. It looked a lot worse than mine. Scary to think about that being located where it is.
I just caved in yesterday and ordered a new fuel pump and sender unit for the right side. If I have another issue, I might try a Google scavenger hunt on the numbers on that 40A connector.

It's not really the connector, it's the issue that the filter gets dirty and starts to make the pumps work harder, needing more power until it fails. The real alternative would be to reengineer a fuel filter system without it being attached to the fuel pumps, so you can change out the filter every 40-60k miles.

Denroll - It seems to be related to Racetronix, etc.

Above looks familiar, doesn't it? I suppose I could be wrong, but why we have to guess, I have no idea. Love the guessing games we have to play on this board.

I did not replace it with an inline aftermarket filter. Even if I did, those inline filters support power much greater than anything an M113 has produced so that would not be the bottleneck in our system.
Looks like a Fore piece!

I cant see that being the case. The billet inline I have flows some silly amount...don't remember the flow numbers, but with the factory filter removed and the modified fuel line from the tank and rail its got to be better I would think. My concern was the actual filtering due to the crazy flow rate. Could be wrong but I would rather have it set up this way.
