Re: terrano dying after a few k's

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

Re: terrano dying after a few k's

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?

Re: terrano dying after a few k's

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.

Re: terrano dying after a few k's

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.

Alga Ihad thought about that too

Re: terrano dying after a few k's

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

Re: terrano dying after a few k's

I had the same problem, It is the priming pump which is letting air into the system. I replaced the filter and put an electric inline pump so when I needed to prime it I could

Thanks all for your input its given me some new directions to follow, Bitsathis could elaborate on the type of pump you fitted and what did you replace the standard filter with?

Re: terrano dying after a few k's

I had a terrano for a couple of yrs. I remember reading they were prone to fuel lines corroding. Fuel hose is pretty cheap, run a new fuel hose from the tank [ i think you get at it under passenger seat or a cover in the back somewhere] to the engine

Re: terrano dying after a few k's

Fitted clear lines replaced primer pump and filter with one off another car.....no change drive for a couple of k's then it dies , Ican crank it for 30 seconds and it coughs and splutters and starts or i can get out and pump the primer. Starting to feel like its the injector pump thats the issue, sad as its not worth spending any more bigbucks on the old girl. Will try clear hose from injector return line but im not feeling confident. The bloody thing will sit and idle perfectly for an hour but if driving you get 5 minutes then its over

Re: terrano dying after a few k's

Don't scrap it yet, I don't think it is the IP. Sounds like a restriction in the delivery from the tank causing it to suck in air somewhere when using higher amounts of fuel. Time for bypassing tank altogether, tie a Jerry to the bullbar or put in passenger footwell. Take a hose from jerry directly to the ip thru a small inline filter. Leave return alone for purposes of the test. Report back when you have done this.
Edit
I now see Tony has already suggested this.
