But what about these that I just found on Summit Racings homepage:
Summit Racing® Heater Hose Adapters SUM-390007 - SummitRacing.com
Heater hose adapters. But I don't understand from the photo how they work...
Do you simply put the 5/8" hose into the 3/4" hose and clamp the connection?? Will that be leak free?
If so, I might have enough space for this.
The Summit connector would use the 3/4" hose that's included over the nipple on the heater, then the included 5/8" OD piece is pushed halfway into the 3/4" hose, then your 5/8" hose is pushed over the other half of the included 5/8" OD piece and the whole thing clamped down.
