... resealing but I'm not going to be able to do they for a while due to time constraints and weather!

Is there a quick fix? If I dry it out, can I pump the external gap full of sealant (or even expanding foam), or should I just cover in duck tape until I can do it properly?

It's a weird/stupid ...

We've attached an airline ho the pipe under the bonnet and blasted air through before. But if yours won't blast then maybe its kinked somewhere?
Sometimes a motor will make a noise, but still not pump, because the impeller has failed and isnt spinning.

Investigating further - it's definitely the main length of tube that runs from back of van to front. This seems very difficult to replace so how do I clean it?

I attached a bike pump to the the front end to try to blast some debris to through but nothing. Feels completely blocked.

... Now after a few weeks it doesn't seem to be working at all - either when driving, ignition on or in stationary. Fuses appear intact this time.

All other electrics, leisure battery lights, water pump are still working. It's a 12V Vitrifrigo fridge

Any ideas on how to start troubleshooting this?

... will drain the battery. The main thing that will be on 24/7 is a compressor fridge. The rest will just be occasional things like LED lights, water pump for the tap, charging phones, etc (It will all be 12v). So the solar is literally just a back up and/or just to keep both batteries topped up while ...

Hi Geoff
Thanks again for all your help. I've got an auto electrician booked in to come and have a look . I'm really hoping he can trace the problem. I'll let you know how it all goes
Thanks again mate.. really appreciate all your help

Vibration, heat many reasons why it may not short all the time. Normal method of tracking these problems down is list all the end points and connectors and then disconnecting/unplugging and testing at each point you can intercept the loom to test, this also leads you to look at the physical loom to ...

If it is a damaged wiring loom would anyone know why it doesn't blow the fuse straight away? I'd have thought it would blow as soon as I turned the ignition on but sometimes the engine will run for 30 seconds, other times a few minutes even though it makes no difference if I turn lights on, rev ...

Oh..that's a shame...sounds like a bit of a nightmare to find.. wouldn't even know where to start
Thanks a lot for your help mate

No there really isn't anyway to check it out, I wouldn't expect to find a fault in it either, if fuses are blowing then a damaged wiring loom tends to be the first suspect, not faulty electronics.

Just a thought but is there any way of me testing the ECU board or looking at it myself to see any obvious signs of failure?
Thank you

Thanks again Geoff
Someone did suggest buying an ECU and fitting that but I just don't want to guess at it and keep throwing money away. Such a shame as I love this van but looks like after around 10 years of fun it's finally had it's day with me
Thanks again

Yes just checked other than the fuel cut-off valve all the fuel pump bits are fed via the ECU supply which is also fed from that fuse but controlled by transistors in the ECU, normally transistors will fail faster than fuses can blow! Fuses protect wiring primarily and not what is fed by the wiring ...

Hi Geoff
Thank you so much for your reply. It's a P registration so I think it's 1996. I just cannot work out what is blowing the fuse. It blew about 3 months ago but seemed to be an old fuse so just put a new one in. I had no problems up until last weekend when it blew after about two hours into a ...

What year is your van ? The pump is mechanically driven but does have some electrical feedback involved in the timing of operations internally. I've never seen any reports of it causing fusing problems. However year is important as the design of the pump has varied over the years.
You can find the ...
