Cutting out

My disco 1 starts up a dream but as soon as you give it any rev's and release the pedal it chugs and dies. I have noticed there is air bubbles in the fuel line coming from the body but no leak. Can anyone help me with this please?

Hey Disco, sorry I can't help but have a bump and a "welcome" for your first post.

Sounds like the typical fuel feed pipe cracking where the pipe goes through the nylon/plastic fuel tank lid. You need to peel back the carpets and foam backing in the boot, open the cover, 6 screw, probably rusted, and check the top of the fuel tank cap for leaks in that area. Mostly doesn't actually leak too much diesel, and therefore hard to detect, but a leak here can and does draw air into the system.

I would suggest that,assuming it's not an EDC auto, you have a fuel supply problem.

As has already been said it could be the pipes corroded on top of the tank, but it could also be a blocked fuel sedimenter (very common) or a blocked fuel filter, or a malfunctioning fuel lift pump.

If it were me I would go for this order:

1. Check & clean fuel sedimenter;
2. Change you fuel filter;
3. Check and replace as neccesary the pipes/connections on top of the tank.

Good luck and a Merry Christmas to you
