    terrano dying after a few k's

    Hi all just been trying to get my terrano td27t back on the road after a few months being parked. The old girl startswith some cranking and when I drive it its ok for a k or 2 then she dies....I get out pump the filter primer a few times and we are off again. At first I suspected bad svo mix still in tank so I added 50 litres of diesel....started ok drove off and a few k's it stopped again......changed the fuel filter , changed a clear plastic prefilter I have before oem filter and also checked to see if the mini filter was clogged up on the pump......found out no mini filter was there, so back to drawing board. Thinking it could be an air leak so I trimmed off the ends of the fuel lines and refitted....no joy. Have heard about fitting clear fuel line and looking for bubbles but at 3.30 on sunday couldn't find any at supercheap or repco. Anyone have any ideas on what I could try??? Oh I cracked the injectors with motor idling as well

    You should be able to get clear plastic hose at all fine hardware stores.

    Be aware that bubbles in the output of your fuel filter hose does not necessarily mean an air leak.
    It could also be a clogged fuel filter or blocked fuel line prior to the fuel filter

    Do you mean plain clear tubing .......Ithought it would not go well with fuel..
    The fuel filter is brand new....could I use compressed air on the fuel in line prior to filter to confirm no tank to engine bay blockages?

    As I recall, when I wanted clear plastic hose on the output of of my fuel filter I just used clear plastic hose from the hardware. Maybe it was the clear fuel line with the thread matrix through it- Now that you mention it, I do not remember.

    I would blow back through the line to the fuel tank to see what happens, these things can be a pain in the neck

    I have used clear plastic tubing on my 300D as return line hose. It worked well on WVO for a year then was so hard that it snapped where vibration caused the hose to move. Use it while testing and change back to rubber fuel line once the issues are fixed. I have used Nylon air line (Translucent) in the return line for many years. It is much more heavy duty and I have never had it crack or leak on me. It can stand having a hose clamp tighten rubber fuel hose onto it. Fuel hose size = ID, Airline pipe size = OD, so for 8mm fuel hose, use some 8mm air line as an air indication window. Not clear, but will show air in fuel line.

    It may be time to get a couple of litres of diesel and run hoses from the diesel can to the fuel pump and take the return line to the diesel can. Use long hoses and a passenger to hold the hoses in the diesel can.
    Start it up, drive it and ensure that the engine bay components of the fuel system are OK for more than a few k's.
    Then check the fuel lines and hoses to the tank (flow and return lines), also check the tank fuel strainer (if fitted).

    Re: terrano dying after a few k's

    Had a problem like this on my canter truck, tried everything including re plumbing, putting air through the system draining the tank and nothing worked. Turns out the new main fuel filter was a dud and once changed again, everything was fine. Have come across a couple of dud fuel filters over the last couple of years, as they all seem to come from china, their quality control may not be very good.

    Artrix, if you want some clear hose in your system, try 12mm food grade nylon hose. Have that in all my vehicles, it replaces the 8-10mm metal fuel lines from tank to as close to the engine as possible and always have a push pump in the system. Have found having that extra pump brings performance back to dino standards, you really notice the difference in a turbo engine. Many times in the sahara have forgotten to switch the pump on when starting somewhere and wondering why it didn't have grunt it normally has. Switch the pump on and off she goes.

    I'd put a cheap ebay push pump near the tank and 12mm lines, so you will have a fool proof pumping method and be able to see if the fuel is coming through properly.

    My new series 80 1hdt cruiser has the push pump wired to the ignition, as it drives both main and sub tanks. Have a switch under the bonnet to turn it off when fast purging, makes life much easier.

    Hope you work it out
