2003 Ford F550 K3H install with 2 stage valves Hi Low

Don’t hate:D. I’m going to find one tommorow. I could have used just a 1/4" valve for the low side, but I got a good deal on the two 1/2" valves. The ball valve gives me all the adjustablity I need from full flow to no flow. I might just do two check valves just to isolate both lines.

Sent while gathering Allison parts.

Found one for $12. It works just as good as shuting the ball valve, but has bleed off on the low side so it sounds kinda like a manual valve and the high side stays nice and crisp.

Got started on the York compressor today. I made a template out of plywood. I’m gonna have to reroute the upper radiator hose. It looks like I’ll be using a Gates belt part# K081377. Its 138 1/4" long. I don’t have it routed in these pics, but basically it will come off the idler puller above the fan pulley to a idler pulley right before the York clutch pulley then over the York to the power steering pulley.

Got the bracket done. The fill times are pretty impressive.

I use a piece of 1/2" plate and a piece that I had on the 6.0 motor for the dual alternators for the idler pulley. Basically it’s a piece of pipe with a 1/2" piece welded to it, drilled and tapped. The idler pulley I used is one off a big rig tensioner. It has dual bearings and is a solid piece of metal, not that stamped crap that you get on regular cars. The belt I listed worked perfect. Of course I have some pics and vids.

I put a piece of flat bar to hold the upper radiator hose away untill I figure out what to do with it.

Fill times on 10 gals.

Idle @850 rpms 0-150 psi 1:50

@1200 rpms 0-150 psi 1:25

@1500 rpms 0-150 psi 1:02

Idle @850 115-150 psi :26

@1500 rpms 115-150 psi :17

So this is what I found at O’Reillys. I don’t know what it goes to besides Chevy/Chrysler. I used this and a piece of the stock Dodge upper hose. I join them with a pvc coupler till tomorrow when I can get metal barb.

Wow… top work. Bit of effort, but I’m sure the results are worth it.
With that pipe making a high point above the radiator and pump, just make sure you don’t get any air trapped in your coolant system otherwise you could run into issues later on.

very nice ! fast fill times.
I’m gonna use A sanden on my silverado just waiting till I get some time if work ever gives me A break… Rex…

Yeah the big electric pump went out and I was never impressed with it.

I don’t think that I may have a problem with it being this p.p.e dual fuel kit is even higher than the hose I’m using and they don’t seem to have problems.

Wow! Extremely nice work!

Got a metal barb. The hose is 1 3/4" and all they make are 1 1/2" and 2" barb. So my local hose shop took a 2" and crimped it down to 1 3/4" and gave me two nice t bolt clamps to go with it.

Nice install and fill times. It all looks great.
Getting much oil discharge?

I have a auto drain oil mist separator, so I haven’t hooked a tube and bottle to it yet. I do get some oil drops coming from the crankcase vent if I use it a lot. I think a little extension would stop it.

Stiffened it up a little more with some 3/8x1" flat bar and added a hole so I can drain the unit. Kinda forgot about that because I thought I would have to add oil all the time, but it seems not to past much oil.

On the bolt at the bottom instead of just drilling a hole and putting a bolt and nut I decided to tap the flat bar with a 3/8" tap. Getting to the nut would have been a pain in the @#$.

Nice install! What did ya do with the turbo off your 6.0?

Dam I haven’t checked this thread in a while. The turbo went with the motor when I sold it.
