Harrison tank water connection

[RJacobsen]

I'm currently making the radiator connections to the engine and have a question about the Harrison tank 3/4" line. My current plan is to install a fitting in the metal tube that is part of the lower radiator hose and attach the 3/4" line there. Doe's anyone know if this is right or wrong?

Rod - Here are three pictures showing how Brian and I installed our Harrison tank. Our radiator has the inlet and outlets reversed left to right. We did this for a couple of reasons: 1) it matches the way the originals did it, 2) it gave us more room to move the altenator from next to the fame rail to up on top where we have more room. If there are any questions after seeing the pictures, post them here an I'll make sure Brian gets back to you since he designed and built the engine fom the bare block up. The system has run flawlessly since day 1. No temp issues and it fills straight from the tank without any of the burping issues some have to go through.

Thanks for the pictures Bill. Yours is plumbed very similar to how I have seen the rest done. The 3/4" hose that you have plumbed into the water pump is the one that I would like to connect to the lower radiator hose. I don't have that spot at the water pump available for connection because of how I hooked up my temperature sensors. also I don't like the idea of disconnecting that hose to change the fan belt. My concern has to do with whatever effect a connection at the lower hose has on the rest of the system and the expansion tank in particular.

Bill - In your first pic it looks like a braded hose goes into the top of ledge on the cannon oil pan. Where does it come from and what is it for?

Bob - The mystery tube is for the oil dip stick. It comes from the top of the oil pan and terminates just behind the altenator. We chose this model because it matched all of the rest of the braided stainless hose we had the EFI, transmission cooler, and remote oil systems lines. It comes longer than needed so you can trim it to your specific length. You then must calibrate the dip stick length itself. We also have a matching one for the tranny fluid. Just a small detail to keep the engine compartment looking neat and tidy.

Edit: Having just looked closer at the picture, I can see 2 braided lines, the smaller line curving off the the left is the oil dip stick line, and the larger one going straight up is the return line from the fuel rail to the regulator. We feed up to the fuel rails with a similar line on the other side into the drivers side rail, cross over on the back side of the engine to the passenger side rail, and down to the regulator on the fame rail with the line you see. Sorry for the confusion.

You can look at my build here and get an idea of how mine is done. I coppied Bill's mounting bracket for the tank.
