Radiator Hose Question
 

iam trying to install my CR motorsports radiator into my FD but the problem is the out and in hoses are 1 1/4inch id. and the fd ones are 1 inch. ive tried parts stores like kragen,autozone,napa and a drealership they all pretty much refer to each other i also went to home depot but i couldnt find anything anyone have an idea? thanks a lot for reading this.

Summit Racing sells some radiator hoses with different adapters. I'm not sure how well they work, but that might be an option.

EEEK MY BAD water pump in and outlet hose size id was 1.5 inches the radiator is smaller

also summit racing doesnt have the sizes i need

Yes they do:

You'll need something like that which comes with adapters.

thank you can these hoses be used for upper and lower? what length do u think ill need

If you are mounting the rad in the stock location, it would be:

Upper: 25"
Lower: 13"

If you are not mounting it in the stock location, you'll have to do the measurements yourself.

lower

upper

these are cheaper than the ones you mentioned will they still work? thank you :)

If you select the proper lengths that you need, it shouldn't be a problem. Cutting those hoses doesn't work (don't ask how I know).

Keep in mind that I have never use their adapters, so I don't know how well they work. I am using their SS radiator hoses from Spectre (purchased through them) but I have 1.5" on both sides.

the thing is no one sells hoses that are 25 or 13 they sell as 24 and 12... so i would have to cut it wouldnt i?

Summit has them (I bought them). The problem is that you'll have to find adapters for the hoses. The hose kits with adapters are the 24 and 12. 1" shouldn't make too much of a difference, you just need to make sure you have enough meat of the hose to clamp it.

Well I needed to relocate my top rad hose to clear my air cleaner (Camden s/c FB) so I went to Canadian tire and they left me alone to go through "all" the hoses to try and find what I nneded. Result, one with a perfect bend to celar the underside of my 14" drop air cleaner base that needed some trimming to the proper length to fit. Just look outside the box.
