Fault finding and Sound proofing

Recently I managed to get a few days working on the Defender between a full kitchen refurbishment, which is taking a lot of my time.

Firstly I did a bit of sound proofing; condensation from the roof was starting to become a problem inside the cab. So I brought a kit for the roof, rear load area and under bonnet from NoiseKiller.

First off I started off with the roof section. Easy to fit, not particularly interesting and quick. So not many photos here.

Next was the rear load area. Again very simple and quick.

And to finish, under bonnet.

The effect of the NoiseKiller is noticeable straight away, even though the front area and 2^nd row isn’t done. Plus there is also a hole through to the road around the gear stick! But the interior is much improved, and the condensation is also put at bay. Job done!

Then back to trying to find the cause of the running issues while under load. I tried a few things this time around, firstly:

Temporary fuel pump. I tried this two ways. One way was with a new temporary fuel tank mounted in the cab with the pump, and the other way was to add it mid-line of the fuel line to work in conjunction with the tank fitted pump. Both were inconclusive, with the in-line option resulting in the Defender barely running at all. So no joy here.

Next thing was to take a negative feed straight from the battery to the chassis, to ensure that all items earthing from the chassis (Ignition, coil, fuel pump) were earthed correctly. Again no change.

Then I decided to take the carb apart (again) and check the float levels.

They were set up, and reinstalled – no change!!!!!

 

So another few days down and still no resolve for my issue, which is extremely frustrating.

I pondered my next move, and after much consideration I opted to buy a new tank mounted fuel pump. During my hours of fruitless fault finding I had spoken to Safari Land Rover who are nearby. They said that if I had used and aftermarket (Britpart) fuel pump, this would be the cause as they have seen this issue many times before. I have fitted a Britpart pump, and this is because the cost different between the Britpart and the Genuine Lane Rover is £230! With the cost in mind, I wanted to be sure that this was the culprit before shelling out. And as I can’t think where else to go with this fault, the pump was purchased. I await delivery and time to install……….
