It's an eBay 044 dual. Some sellers let you order the thicker rubber for the thinner super duty pump. I just made the reducer from some rubber I had laying around.

Downside, it doesn't have a real mounting hole so I had to drill in the center of the bracket. It also requires the 044 check valves and some aluminum crush washers for sealing.

If I did it again I would go with a single AEM 400lpm and just keep a second one it cab.

The single AEM will support the same, if not more, than the dual super duties It requires less space and less fittings.

Only reason I originally went with duals was redundancy.

I already bought dual SD pumps, but I think I will stick with the mount I already have I was just wondering, I am going to mount my filters and pumps behind the saddle tank under the truck

Today I'm ordering the new clutch for the road ranger conversion.

It's a 109508-11Y it's the right model fit the t444e and dt466e flywheels, self adjusting, and extended lube intervals.

Any used RTLO 13 speed to be honest. Just so long as it has a sae-2 bell housing which I found a company that will find and install the correct bellhousing from their yard. The one in looking at currently is a RTLO-16713 mainly due to it having a PTO pump on it already.

I ordered a oem 206ss (FP62062RS2) bearing which im going to check and make sure it's the correct inside diameter 1.18".

I'll probably also have to get the drive shaft shortened.

There is a guy on the trucker forum who convert his dt466 to a RTO6613. His was a complete drop in from a 6plus.

Edit: if you have an automatic there is a chance it's an sae-3 bellhousing.

I would be interested to hear how your transmission swap goes. Also I would like to hear your thought on driving a 7.3L with a 13 speed.


I wish there was a lighter 13 speed with two or three od gears with top OD in the .61 to .65 range.

Well, First trip through the hills with this set up, on the way to pick up a car.

I think I'm "decently" tuned now at least for the option available to be.
Yesterday was the first trip I got to take to and from the WV hills grossing 27k. It was probably the best trip I've ever had. Before on most of the hills I would pull down to 25mph. But this time I never dropped below 45mph. Most of the 45mph hills were because there was another truck in front of me or if it was a long hill I had to run the splitter to raise rpm to cool it down. Dropping road speed in the process since the splits between gear ratios is pretty vast on this transmission. On very long pulls it would climb slowly to 1250/1300. So nothing really terrifying and I probably could keep it up there but I'd rather not have this rig break down any time soon lol. This also leads me to believe the old AD injectors were junked even though they would pass the buzz test.

My father's house finally sold so we have to start getting stuff out. We started with his car.
Also I don't have any boost leaks or uppipe leaks. Once I get my exhaust pressure gauge hooked up I'm thinking of cranking down on the waste gate some.
Besides that do you know of any other things I could do. I thought about water/methanol, but everyone is like "you don't need that with good tuning".
I didn't even have to drive this trip. So I got to get some photos and videos.
P.s. please ignore my duct tape gauges ��. I have a piece of kydex I need to bend for them.

I've also decided when I do the transmission next year I'm also going to chop the end off frame rails and lower the bed to accept 5th wheels. Plus pull the bumper pull hitch closer to the rear axle.

Just scooting right along! How's the fuel economy? Any noticeable difference on long hauls?

It actually seemed to stay the same. So it didn't get worse at least giving how much of an improvement was made. I really think a transmission with an OD in the flat land would really raise it though. My reasoning for this is I'm watching the fuel gauge and the mountains aren't what pull it down. It's the final leg doing 2600RPM non stop when it doesn't need too.

I'm actually washing off the vehicles right now. Then I'm going to to gas station. I think I used 65-68gallons on way up. But I'll find the receipt.
