1'' bypass hose issue

If you want to remove, soak in PB Blaster and let sit. Be careful if you use heat.
Alternative way is to cut "cross hairs" in the end with a hacksaw blade. You've cut it into 1/4's, now you can "fold" each 1/4 in. Hope that makes sense.
No need to change the fitting, I had the same issue with mine. I just cut a piece of 3/4 heater hose ( about 3/4 long ) and slid it on the 3/4 fitting. Your 1" bypass hose will slide over the 3/4 heater hose. You can use a little bit of silicone between the two if you want. I ran mine like that for years until I installed my LD340 this spring. Bobby
hmmm......good idea,thanks
