Have a genie in a box just lately seems to be suckling in air from somewhere.  Tightened everything up but no joy. Any ideas

Looking at the pic the obvious thing to me is to check the inlet hozelock male on the box to female on your feed hose as maybe the couplings are warn so when the pump is running might be sucking in air from there?

As a quick test just you could change them over with new ones to see if it makes any difference. Or just as a test maybe a hose joiner would do? Depens on the length of feed hose you are using be it from a barrel or tank how long running the pump at full pelt it would take to force all the air out of the system.

Meant to ask are you drawing water from containers or a van tank?

Hi sm urf thanks for reply it's from a tank. I'll try what you suggest

Connect everything up 1 by 1 starting at the tank and working right through to see where the air is,if this happens that's what I do. I've also had a build up of gunk on the inside of the tank preventing it being able to suck any water out of the tank a coat hanger is ideal for this lol

I've found using clear braided hose on the inlet side it's easy to see any trapped air in the system to bleed it out.
When the pump is at full pelt then tone of the pump will also change when all trapped air is out of the system.   
Any restriction or lake of water getting through on the inlet side some type of hose will actually start to collape in on itself (suck together) too

Many thanks. Guys Think I may of cleared it don't really know how though lol. Got another pump in the van so swapped fittings about seems ok now. So may of been the hose lock fitting to inlet as sm urf suggested
