Water pump change - what’s needed

[Stacetop]

Our water pump has started making a strange noise, typically we are on holiday. I have ordered a direct replacement to the campsite we are heading to.

I have a couple of queries. From what I have seen the 12v lead from pump uses spade connectors, I’m not sure of the size and it will be a pain to get to them so only want to do it once when I change it?

So I was thinking of just getting a mixed set and hope for the best!? Can anyone offer any further on this?

do I also need a crimping tool? Or would pliers do??

thanks

My shurflo in a rapido has blue 6.3mm spades. A decent crimp tool will give a more robust joint, with pliers you are likely to revisit the job. The colour crimp depends on size of wire youve got.
Edit example

Being a Hymer group van it probably uses mate 'N lock connectors, you can get them on ebay and a crimp tool for non insulated push-ons works OK.

These are the 6.3mm spades on my sureflo in a Rapido. You'll also need an adjustable spanner or 8mm socket to remove the 4 bolts holding the pump to it's mounting, in my case it's fixed to the tank but it varies from van to van.

When I changed a pump while on holiday, I twisted the ends together and wrapped in tape.

I know it’s not ideal but I was in the middle of the Alps during holiday season.

It worked and I then forgot it for about three months till I remembered to do it properly.

I needed to drain all of the water out of the system. I bought a couple of taps from a caravan shop to fit either side of the pump in case I needed to do it again.
The low pressure side works fine but the high pressure side leaked and was removed. Plan ahead and get a couple of decent stopcocks.

We went on holiday in Germany and using stellplatze so sourcing everything was moderately difficult.
