3/8"

I used better 3/8" hose from the parts store on my installation. The hose that ships with Hayden coolers is a little tighter than normal.

 

I ordered this hose:

And these clamps:

Clamps are a bit too small. FI10's (15-17mm) would be right.

 

i didnt use any connections, i just got 7' of 3/8" hose from napa and cut the old soft line off completely and used the new hose on the hard line, didnt feel like splicing it in and using eight camps over the four I needed

 

Did you flare the hard line? I spliced into the soft section of the return line, but the new connections are brass barbed splice connections. 6 clamps total, not 8. They aren't going anywhere.


I used splices like these:

 

thats what ill do thanks

 

Yesterday I got rid of the leaking rubber hosed quick disconnects on the oem trans cooler lines. For now I just spliced into where I had hooked up the B&M cooler. Eventually I'm going to go with 1pc lines like post #4 (Nolan) did. One more thing. The fuel injection clamps are the cats meow. They do hold GOOD.

 

Good to know. I think I'll swap mine out.

 

wrong info.

 

I've already got this set in my cart:

 

Your in good shape then.

 

As a follow up to this, the correct size for the fuel injection hose type clamp for a 3/8 transmission hose is FI8, 9/16-5/8 or 14-16mm. FI10 is too large.

 

FI10 too large huh? Fixed #9.
