"pressure" water/ jabsco gravity pump faucet combo

[TBG]

I tried replacing my gusher galley foot pump MK III with a Jabsco electric pump and faucet combo from WM ( only $85) with minimal success and very minimal pressure It's a gravity pump that we mounted where the foot pump was Has anyone had better success with this product or another way to add pressure water ? The foot pump in the head works fine and I am happy just getting the pressure water in the galley.
