hoses for ram-jet to Ron Davis aluminum radiator

[Cirbo]

Hi Guys,

I've done some searching, and some asking, without any success.

Can anyone provide the part numbers for preform hoses that will fit between a ram-jet 350 and a Ron Davis aluminum radiator?

TIA,

Cirbo

top: gates 20416

bottom: Gates 20573 if the rad has a 1.5" lower connection; If your rad has a 1.75" lower connection see this link post 3:

here's a couple pics of my top hose. If you have something in the way such as an AC compressor/other then you may have to bend some wire and bring home a few from the parts store. Here's a link with some pics showing what I mean.

Good data, but I've got the serpentine belt system on the ramjet. I'm not sure the hoses will fit over my alternator.

I see what you mean with the alt looking at pics in your build thread. The bottom should work. For the top I would start with a top hose for whatever that engine came out of. That certainly has to address routing around the alt.

Another thing you may want to consider doing is to bend up a pipe and use a length of hose at each end for the connection.

One thread shows a 20573, and the other shows 20537....

Can you confirm?

TIA,

Jim

20573. But again, measure your lower rad connection and buy the right one!!!!!!

Top fitting is 1 1/2 inches, and bottom is 1 5/8. I also found this picture while surfing V8 installs. This one looks about perfect, now if I can only cross it.

My shop did the installation of the ram jet in the blue FJ45 that is posted in Cirbo's photo. If you want, I can go back through my records and see if I can come up the the hose number for the bottom hose. The top hose is quite visable. My web site has a couple more photos.

That's amazing. I wasn't able to recall where I found the picture, but the work is excellent. Any data that you could come up with would be much appreciated.

On a somewhat related note, is there any chance that you would consider hiring me to work in your shop. I love that area of the country, and desparately want to move there.

Crossed those numbers at NAPA, but they aren't the best fit. Back to the drawing board....

 

[dgangle]

So you crossed the part numbers, brought home the hoses, put them on/in position and somethings amiss. What's the problem?

 

[Cirbo]

Exactly. Poor fit on the top hose. I can put it on, but it is crimped and stretched more than I'd like in a few spots. The bottom doesn't even come close. I'm leaning towards the stainless steel units from Summit right now.

 

[dgangle]

I give up. I don't know what to tell you and I'm getting tired of guessing.

I found mine by making a mental picture of what was needed, going to an autoparts store with a good selection and pulling everyone off the wall that I thought did, might or could be made to fit. Repeat 3 more times, cut up/ruin a few and return everything that doesn't fit. Then be sure to write down what works!

Your build is pretty impressive, and attention to detail awesome. I'm sure you can figue it out.

Don-

Thanks for posting that pic on your site. I stumbled on this a while back and it was a life saver. I searched and searched for this top hose forever (with several HACK attempts of other hoses) and your pic made it easy.

I'd be interested in the lower hose # too if you find it.

Maybe a little more expensive but this stainless steel radiator hose works great and saves a lot of trips to the parts store. I think one 36" piece cut into two sections will work for both upper and lower, but order extra couplers.

Wow, $40-120. That kinda coin can buy lots of creativity.

 

[Cirbo]

Yeah, that's the hose I ordered, but wasn't smart enough to order one.....LOL

I looked back through the files for the lower hose numbers. The number I came up with on the Blue Fj 45 was NaPA 8336. I had done an earlier conversion where the engine was in a slightly different location and I had two numbers Napa 8025 and 8387. Can't tell you whether they are right or not.

Thanks Don. I'll take a look at all three and see what might work for me.
