Random tip: heater hoses

On the grand total of 1 LS swap that I've done I ran into an issue with the heater hoses hitting the inner suspension/fender right where they come out of the LS water pump.

To fix this I sourced Dayco heater hoses with a bend molded right into them, and it worked great. I have some plastic anti-abrasion covering on in this pic but its actually from before, you don't need it, as they clear nicely now. I've also replaced the two-clamp funkiness with better clamps.

Here's an example pic and the links to the parts, if you can make use of them.

Re: Random tip: heater hoses

Couple questions... why two different part numbers? Aren't both hoses needed the same size?? Thank you!

5/8" hose will work, but will need a lil' bit of heat and some gentle persuasion on the larger fitting.

Re: Random tip: heater hoses
