Here's what I have going on for the new fuel cell. It not done yet but here's the gist.

The sump is similar to this:

Except there are two Walbro pickups inside it, one front and one rear. There is a ceiling above over half of the trough of the sump at the back that completely covers the rear pickup. (The fuel pump sits on top of the ceiling.) The fuel return line returns in right there next to the pickup via a fitting that is welded into the side. The only way for fuel to escape the trough is the front of the trough through a small hole that I made in the bottom. When the vehicle is level it will fill through this hole and at the back of the trough via the return line. When going up a hill fuel entering the trough will have to completely fill the back up to the level of the ceiling of the trough. That is roughly about 5" so the rear pickup will have no option other than to be completely submerged. Even if I stay on the steep hill for an extended period the fuel coming from the return will keep the pickup submerged. When going down a hill the front pickup will be the lowest point of the tank so it should stay pretty much submerged. But even if it doesn't there will be fuel rushing past it from the return line in the back. Side to side movement should not be an issue because of the sump having walls but again, the fuel return is always filling the sump as backup and fuel can not escape the trough of the sump until it has completely submerged the rear pickup.

Nice work! I admire your persistence is resolving issues and trying new things.

Idea - add an external site tube so you know approximate fuel level throughout longer trail days.

I'm going to add a full-on fuel gauge as soon as funds allow. I might have to go a trip or two without.

I had the gauge like you are talking about on my last one but the clear tube I sourced reacted with the gas and went so hazy that I couldn't see the fuel inside.

J.J., I am not sure your LS2/fuel pump will be happy with only 2 walbro pickups. I run the same setup in my TJ and when it gets low enough on fuel that one of the pickups becomes exposed, my pump and LS1 become very unhappy.. You may not have any issues due to your sump design but I figured I would share anyways:flipoff2:

Thanks. What do you mean by unhappy? What exactly happens so that I know what to look out for? FP drops?

I have always wondered if the Walbros are enough and, to be honest, have kind of always doubted it. Yet so many report success with them and they are equal in outlet size to the pump inlet. I have a plan to eliminate them completely if this doesn't work out but wanted to at least try it first.

It would be really cool if Timmay would get off his ass and make the bigger versions. Its not like he does anything all day. :)

I never put a gauge on it to check pressure, but the pump would get extremely loud and the engine was noticably starving for fuel and it would get sluggish and even break up at higher RPMs

Sounds like what happened when my pump was on the fritz and wasn't supplying enough pressure according to my gauge. (Except for the loud part, my pump got really quiet when it was starving.)

It looks like your 205 shaft fixed your driveline carrier issue? I saw when you first posted it up and I had just purchased mine at the same time. I pulled it out today and found twisted splines. If the 205 shaft did cure the issue then I will be on the look out for one. Mine was the 32 spline shaft.

I believe it did. It has already taken more than the first one did but I have not had a chance to truly beat on it yet.

I put a hell of a hurtin on mine and it didnt break just twisted. I dont know when it accured though. Could have happened months ago? I am actually suprized it held up with 54" tires and no concern when throttle was needed. If I can find a 205 I will do like you did, if not then I will toss another EOR shaft in there. Didnt mean to derail your thread with older issues but you seam to have found a great solution.

One more thing, what rigs had a 205 with slip rear shaft?

So why did this get sold and what are you wheeling now?

I just came to enjoy a weekend with my daughter more than a weekend wheeling. Any time I was out on the trails I was just missing her and counting down the weekend until I could be back with her. I have no rig anymore and don't plan to ride again any time soon.
