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.

Clean

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.

If you end up having another issue, shoot me a message and we can work on getting you fixed up

OUTSTANDING You should show this to MB engineers.. That connector is Scary

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.

I replaced my fuel filter with a brand new aftermarket unit before my over current condition on the fuel pump hat materialized. Additionally, the 340LPH pumps require a whole lot less load for the same flow so even a dirty filter isn't working them as hard as the stockers are working.

Hulk

For some reason the aftermarket filters that are inline are still making the pumps work harder. It's just a bad design. The SL55 are much easier design and don't have the same issues

jcjmw

mmm...can you put the oem sl55 pumps inside the e55 tank?

Hulk

Nope, different design

Denroll

What would have to be changed? Already sounding like a "more trouble than it's worth" project, but it would be cool.

Hulk

Everything the pumps wouldn't fit in there, the gas tank would not work with those sl55 pumps

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.

austingtir

Your the man bro. Iv been thinking about doing exactly this for my own car as I hate the way that fuel can wick up through that plug!!

das eighty

Holy crap. Well done.

Nice piece of work! Can't wait to see what you come up with when the other side goes brittle.

rockthemullet

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.

Rockthemullet, that is some pretty work there, are you going to do a limited production?

chawkins2001

Very nice work Eric Looks like a Fore piece!

blackbenzz

Awesome work How many times does your traction control light blink per second now?

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.

rockthemullet

After some more testing I could do a small group buy here. The design is proprietary to my machinist so I can't hand that out to anyone and I would need to find a better supplier for the bulkhead and connectors. If there's enough interest, I'd have no problem putting the time in to get these out to others

I could anodize it black and etch the name in the top, haha

Nice work

Wow. That looks great.
