Slight drip at pex fitting to water pump hose?

As the title states. The flexible hose that comes from the water water pump that connects to the pex line fitting keeps dripping slightly. It drips more when it cooler out than when it's warm. I figured it was because of aging so bought a new hose 3/4" OD x 1/2" ID Braided Vinyl Tubing. Made sure it was snug up to the stop on the pex fitting, tightened the hose clamp with a ratchet instead of a screwdriver so it was tight and not snug. It's straight on...no weird angle or slight **** to it but it still is ever so slightly getting a drip build up where it connects (it is this water connection not on the other side by the pex tube). Is there something that can be applied to the hose connection before sliding the hose on that will stop the slight drip.
