could we not use our compressors to to presure up the tank via the return line inlet after opening the bleed screw at the injectors ??

That has been suggested and someone did say that it worked for them... but gee, too much pressure and?????

The LR mechanic said you need to pressurize the tank to force any air bubbles out. Using your compressor is doable, but how to you do it, since the compressor nozzle is too thin for the fuel inlet pipe?

As said... there is a post where the guy just stuffed some rags around the air hose. I guess it only needs a small amount of air.

Ive bleed up quite a few engines using a airline and a rag in the filler neck, it doesnt need much air but best if there's two people about as you normally cant see the bleed point from the filler neck and you get diesel everywhere!

I was able to restart my Puma after getting air in the fuel lines while bleeding the fuel filter by disconnecting the inlet fuel line above the injector pump and back filling with fuel. Be careful about dirt which could damage the pump. Also be careful about the fire risk handling bare fuel.

I reconnected the lines, put the accelerator pedal to the floor and cranked the engine. The car started but ran roughly after about 10 seconds. Pumpimg the pedal gently to rev the engine it started to run smoothly after a minute. I did not used any special tools.

If you had too, it would probably work in the bush if you had this sort of problem, but be careful.

Hi All

Have had an experience where I had to drain the fuel tank in the puma so it being a new vehicle and having owned it for less than a week I was feeling pretty good at least it hadn't been started so I took the fuel filter off and it started draining - stupid me took the cap off - don't know how long it might have drained if it hadn't been disturbed.

Refilled the fuel filter 5 Micron by the way, pressurised the tank and good to go

This has been my only concern with the puma, what if I damage a fuel tank out bush and need to refil and re-prime the system.

I like the discussion about simply putting an air line in the tank and presurising the system

But what about the tank breather? That must also be blocked I assume and I cant find mine even though I have been looking for it.

The dealer has my car now for a warranty issue plus its 10K service, also my tank leaks when i fill it so thay are doing that as well. When i first saw the diesel leak I crawled under the car to find the leak "appeared" to be on top of the tank - i.e. between the rear floor and tank top - how do you get to that easily?

Hi All

All I did was rags and air into the filler cap and it works no worries, you can hear the air escaping through the tank vent and if you have the filter off you can see the fuel coming out

If you guys want to drop make a simple job complicated feel free to drop the tank and all that.

Also if you are out bush remember that you can pump up a tyre to about 70 psi an use it as a air tank if needed
