Lower radiator hose....help
Hey gang
I have a 427FE and the AFCO radiator from FFR in my Factory Five roadster and I am looking for a lower radiator hose. I have seen on the ERA website that you can cut a GY or Gates hose and use an aluminum center section for the straight away and piece together a hose, but I don't know what that aluminum straight away piece is from. What has worked for you guys? I would like to keep something clean and origional looking and RUBBER hose. Thanks |
It is just a piece of aluminum tubing with pieces of formed hoses on each end. Very easy to fabricate.

Often parts of two different formed hoses are used on the end of a piece of straight aluminum tubing. I had an unusual situation that required creating a "Hard tube" from several pieces of mandral bent aluminum tubing, it works quite well. Click on the picture for larger version.

I have a Lone Star with a small block. I drove my car with the hose under the frame for years but I was afraid it would hit something and leave me on the side of the road.
A couple of years ago I routed my lower hose over the steering rack and frame with two 1 1/2" copper 90's and and three short pieces of copper pipe. I brazed the 90's back to back so I could route the hose up and over the frame. Works great. Dwight |
We usually get aluminum tubing from "metal-Supermarkets" cut them to size, clean them up and even mill a hose clamp landing in them.
works great. |
Get a piece of aluminum tubing, cut to length, then take it to a (hot rod) shop and have them put a bead around each end (so your rubber tubing can't pull off) with a bead roller.

Cheaper and not as pretty
dlotz You can also use exhaust pipe for this and it is cheaper and easier to get at any auto store, 3 things to do if using steel pipe, double clamp it 180 degress apart on both ends. Lite coat of grease on each end. If you can get someone to roll the ends 1 clamp will be fine. The other thing is to get a universal exhaust hanger for that size pipe and hook it to the frame and the pipe. This will take the load off the pipe and stop vibrations and have something come loose and could leak or break off. If you have a torch setup you can make your own pipe with a bead lock on it by cutting about 1/4" off the end and heating it until it expands and slides over the end of the pipe. Let cool and it will lock on. Blaze a coulpe of spots and it is good for life. Exhaust shop can do this too. Rick L.

Each connection has the potential for a leak or failure, be sure they are secure. If you can't put a raised ring on each end of the metal tubes (sometimes difficult to find someone with "That" tool), put 4 "Dots" of weld material around the end perimeter of the tube which will prevent the hose clamp from sliding off. You can also put the fan switch in the RH lower radiator tank. I use the same 22mm fan switch pictured above, they are used on VW, Porsche and others.

Check Jegs they have tubing and connecting pieces!

Anyone know where I can get a bigger one? |
Dan that's an easy one for me to make for you if needed.

WOO HOO, more fabrication time!
Ok
So I am going to make my own adapter here at work on the lathe. Here is my drawing/dims. Anything look wrong to you guys? 1/4 wall should be enough, but I am wondering if the barb should be deeper than 1/8"? Should I make the O.D. on the adapter slightly larger than the I.D. on the hose say maybe 1/16" wider on each side (1/8" total) so that the hose has to stretch a little to get over the barb? http://i108.photobucket.com/albums/n...radadapter.jpg |
I would make the OD of the tube the same as the ID of the hose, check the hose size is it 1.875" or 1.750? Check the part number of the lower hose with the manufacturer for sizing. You may have to start with 2" aluminum thick wall tubing. The barb does not have to be .125 deep to allow for retention of the hose .065-.080 is plenty, eliminate the sharp corner on the barb.

Yes, I plan to round the edges. Didn't want to get too technical with MS powerpoint and paint! lol |
You're on the right track. I like these stainless ones and I just weld an appropriately threaded fitting in where needed.http://img69.imageshack.us/img69/1769/parts004k.jpg

Making the fitting slightly larger then the hose i.d. is a good idea. On your barb... .125 high barb is ok..but make sure you take the sharp edge of the inside lip. When the hose goes over that barb and you tighten it down with a clamp you can in time cut the hose if it has to make too sharp of a bend...especialy if there is 90* corner. Just my opinoin.

forget what i said...someone else already said it.
