Bend a piece of wire into the correct shape, go to the parts house and go through their inventory. You will be amazed at how many different shapes there are.

Make sure you measure the inlet and exit size also. Ask me how I know ???

From Entropy's website:

For the upper hose, a 1990 - 1995 Eclipse upper hose is almost a perfect fit.

I think I'm going to make mine from stainless tubing. I have the same radiator but using ls2 pump.

Another option might be considering exhaust tubing. a muffler shop may be able to bend one up. If both sides use the same size hose, install rubber hose ends.

After trying a couple of recommended hoses that didn't fit the way I liked, I also took the welding wire/auto store route. A two hour visit to the local Napa hose section with the wires and a set of calipers resulted in good fitting upper and lower hoses. They both had to be cut, but work well.

Absent good info from a like installation this is not a bad way to go.

I have the same setup and it took a Dodge Daytona hose. Works fine 16 inch center to center.

Can you post the upper and lower hose part numbers you got from Napa? Thanks!

The part number for the dodge Daytona upper hose I used is 61782

I had to trim one end but it worked great.

Entropy radiator, truck drive - Napa # 9541 for the upper hose and Napa # 8338 for the lower hose. Both had to be cut, but fit well without any adapters.

Napa part number I used is 8304 for both lower and upper. The upper will need two reducers and both will need trimming to fit.
