Pump fitting leak !

Replaced the old non functioning flowjet quiet quad with the sure flow whisper king, huge decrease in noise. However, I can't seem to get a seal on the outgoing end of the pump. The 1/2 plastic fitting the screws onto the pump has a barb fitting that in turn connects to the hose keeps leaking.

I've clamped it, put two on actually and it keeps leaking. I can't seem to find a barb that starts of larger and narrows so when I push the hose on it increasingly snugs up. All the fittings have barbed ends that are just one size.

I'm tempted to replace the entire rubber hose portion but not sure what type to use as the one on the trailer says cold use only and all hose at Home depot says hot water use for dishwashers.

Any ideas, thanks.

Sounds like the hose you are using may be old or original. If used before on the old pump then it may have indentations on the inside that have not sprung back prevnting a tight seal and that allows the water to leak. I would also look to replace the plastic barb fitting with a brass or even better satinless steel fitting from HD or Lowes. Do the same for the hose clamp - go SS. The hose replacement is also at HD or Lowes - bulk tygon hose - get the stuff with nylon fibers inside the clear tubing - sold in bulk it's not all that expensive by foot. All this is in the plumbing section. Sometimes they have cut pieces that are discounted and you can cut your own and have some as backup. Put some teflon tape on the threads of the barb fiting that screws to the pump housing for insurance. Length of hose and new fitting would probably set you back less tha $20 and last a long long time.

Ditto clancy_boy's comments.
As a quick test, and if you have enough of the original hose to spare, you could snip off an inch or so and remake the connection, the indents as discussed above, will be gone. Also, you can get, for want of a better term, double wrapped hose clamps, and these allow a much tighter fit than a single which can begin to thread strip before getting tight enough.
It might also (unlikely, but possible) be that you need to back off the pressure shut off adjusting screw so that the pump shuts down sooner, and under less pressure.

A wise man once told me he wanted to stay fit enough to run a marathon on his hundredth birthday. Another said he wanted to be shot by a jealous husband on his, I'm with the latter. God bless you Richard.

After 4 trips to three different hardware stores, and several hoses, couplings, barbs etc, it seems to be fixed.

The difference between the whisper king pump and the old flowjet is amazing. Reminds me of the difference between the old style generator db ratings and a Honda eu2000 !

Thanks for the suggestions.
