Hi
I changed my tank in van, but now I've set it up again I'm getting no water.

All I did was just connect tank with same fittings.

I have two pumps just using a splitter from tank.

Any help much appreciated

Put the old one back in .

If you are drawing water from over the top of your tank then your splitter is probably where your issue is. I would try running both pumps flat out simultaneously with nothing  connected to the outputs other than a short piece of hose so you don't end up with a wet van and make sure all hose connections are airtight between the tank and pumps.

If the pumps will not prime then one way to rectify this is to suck (yes, with your mouth) on the outlet pipe after the pump with the pump running. You'll hear the water hit the pump in enough time to move your mouth off the pipe. Works every time.

Well I've tried everything and still no water.

Pumps seemed to be running ok just no water!!

This is driving me nuts,I must be missing something simple?

Are you sure you have put some water in the tank .

Are you sure you have put some water in the tank . 

I was tempted to post that myself  . Best to just start from the beginning work on 1 pump at a time.

I'm going to have to state the bleeding obvious things that haven't been mentioned yet, please don't be offended 
Does the tank outlet have a tap and have you opened it ?
Do you have an inline filter and is it clear ?
Have you re-connected the pumps the right way round ? they may have directional arrows printed on them to show direction of flow.

Break it down into sections.
Is water in the filter before the tap?
Take pipe off just after pumps?
Find out where is stops. SUCK

"Have you re-connected the pumps the right way round ? they may have directional arrows printed on them to show direction of flow."

I put a different pump on my trolley last year and that is exactly what happened. Just assumed the water would flow the same way and it didn't.

Place the pumps lower then the out let of the tank . Ive had this trouble  before ... pump would prime then stop i took the pump out all connected but with a long enough reach to place the pump on the ground at the side of my van . Left it running with hose going bsck into the tank for a few mins then that sorted it . Also make shure strainer / filter before pump is air tight coz air can get through there too .

 CHeck the outlet isn't blocked with bits of plastic.

Does your pumps have filters?
If No you might have plastic from the new tank in the diaphram
