What's a good replacement hose for the rad to coolant res hose?

 

5/16 fuel line

 

Ok so fuel line is ok to use on that? Cool

 

Silicone Vaccum hose seems to be holding up fine as well, its been on my car for a good 5 years with no issues.

 

Really? I didn't think vac hose would hold up for some reason

Fuel line is definitely a good call

 

Working fine for me, too, many years now. Hot coolant does not bother silicone (which is why we use it to seal gaskets) & vacuum line won't collapse on itself.

I'm sure fuel line would be fine, too. Just don't use vinyl tubing or anything like that.

 

I go to Lowes and get the clear nylon line, it's chemical safe. Not sure what it's intended for exactly, I also use it for fuel sometimes, as long as it isn't under pressure, works great. And, it's, clear..

 

^ just dont use it for vacuum... like a brake booster line....

 

Agreed,

 

side note, why cant i edit my posts?

Hmm clear hose would be pretty cool. Would be really sweet as fuel line so I could see my aqua blue colored premixed fuel. Do you think it would hold up to the 2psi my 12a fuel pump puts out?

 

I used it on my weber carb and was running 3/8's line, I ran 7 PSI at one point.
So, you could. You can actually get some clear line specifically for fuel on the web, look it up Joe.
