Flojet Onboard Pump

[SirRogerFFS]

Good Morning Technical People.I think I may have posted this before but just to make sure as my memory is not as good as it used to be .I was away in our van at Easter when the floJet Pump decided to die on us making the onboard water tank useless.When we got home I went to our local dealer who supplied me with a Shurflo pump. Granted its quieter than the Flojet but when I first open a tap in the van there appears to be a lot of air but does clear until the next time a tap calls for water.. Anybody any ideas I would appreciate a little help . Sorry if this goes on a little I have tried to put a smuch down to help you to help me .
Thank you ....Sir Roger

Would it be possible to fit one of these just before the pump and see if it helps with the problem ?
I have two fitted in separate lines and don't have any problems with air unless it hasn't been all bled out properly when filling the system up ..
