Hot Rods A 2" hose on a 1.5" radiator inlet ?

I have a B' engine in my 31 A, and the outlet from the pump is 2" going into the top tank of a stock radiator. Here is my situation: for me to have someone rod out the core, fill in the original filler neck and then add a pressurized filler elbow on the back side of the top tank so I can run my 32 shell, this amount exceeds the cost of several of the replacement all aluminum radiators sold on e-bay. These are for a 32 shell (1" shorter), they have a 90 degree pressurized elbow on the back side of the top tank, come in either 3 or 4 row design, and would be a great replacement at less than the cost of repairing & modifying my 80 year old original radiator. The only issue I have is that none of the manufacturers will modify the radiators they sell & all of them are 1.5" inlet in the top tanks. Does anyone make a hose reducer from 2" to 1.5", or is there a hose available with a 2" on one end and a 1.5" on the other? What other suggestions might any of you have? Thanks

 

You can buy "bushings" or adapters, this is not the exact one you need but it will get you on track.

 

You need a 2" splice nipple. It gets clamp clutter but it's easy

 

What about putting a piece of the 1 1/2 inch hose on it them sliding the 2 inch over that and use one clamp?

 

I seen this done on a Jeep radiator that I modified.. was working well.

Done it many times. In fact that's pretty much how those fluted metal radiator hoses do it and those are on COUNTLESS hot rods.

 

Yes the above works perfectly. If I doubt use double hose clamps .

 

Hot rodding ingenuity at its' finest.

 

Back of hose catalog is sleeves

 

I used an exhaust reducer

 

You can go 1/4 inch pretty easy with the spacer hose between the inlet and the hose but 1/2 inch may be a bigger jump than is advisable.
Here= for 13 bucks and shipping this may be the most viable solution. it is stainless and 4 inches long. https://www.fillernecksupply.com/1-1-2-to-2-fuel-filler-hose-reducer-stepped-joiner-adapter-38-51mm/

 

A flex hose might work too, they come with different sized ends

 

Love to see problem solvers. I learn something new every day here.

 

i've used hoses that had different-sized ends...

 

How about a metal tube upper? Can make the shape you want and either end can be sized how you need it. Something like this:

Fantastic ideas and solutions to a simple problem. For now the best direction will be the stainless tube reducer from Fillerneck Supply and then get back to all of the dealers on ebay for their radiators listed. I need them to supply me with their mounting bracket measurements: heights - widths - offsets , so I can make a good choice.. Aganin, thanks to everyone for your help. Steve

 

I agree 200%. When they first told me about these, I was thinking "Ya, right! That things going to leak like hell!. Well, I was wrong! ( 2nd time this year). They work great, they're cheap, you don't really see them, and you don't need a pile of clamps to hold it together.
I get them from NAPA, but any auto parts store will probably have them.

 

There should be a universal flexible hose that is 1 1/2 at one end and 2" at the other.

 

Rock Auto has the Gates one for $4.75. Jegs gets $11.60. Just sayin'...
