fuel line

can anyone tell me the fuel pipe inner and outer diameter please.

 

[zippy656]

inner 8mm


no idea what it is on the out side

wel the outer has to be a bigger diameter than the inner , or the inner becomes the outer :augie:lol:lol

8 mm sounds big to me for the inner size I think it will be more like 8 mm outer, but I am not going out in the cold now the measure it, Rick

 

[solarman216]

Usually pipe sizes are quoted in outside diameter as they come in different wall thicknesses for different duties/pressures and if the outer diameter varied you would have a nightmare trying to get fitting to match, Rick

Pipe sizes are 8mm flow and 6mm return :thumbs

Are these internal Diameters ?

Excuse my ignorance, I thought fuel just flowed one way, what is the return for ?

thanks

Most diesels have "return pipe to tank", it is simply an overflow what the engine does not use it has to go somewhere,best it goes back to tank to be used again and not on the floor.

Many thanks.

One of the pipes is leaking very slowly just by the chassis behind the back wheel. Like, the most inaccessible place of all ! So going to replace both pipes from the tank (under the carpet) to half way down where the pipes are easier to get to.

Do I need to release any pressure anywhere or will the diesel just drip out when I cut it ?

thanks again

The return was leaking badly on mine.Just be careful when you take the pipe off the top of the tank the pipe on the sender snapped on mine..

Cheers Gav

no pressure but if you just cut the flow pipe it will syphon at full bore, so remove the rubber hose at the filter (top metal pipe) and blow down it till air bubbles in tank, Rick

Thanks for the Tip.

That's the flow into the filter I assume ? I also assume I will have to pressurise the system with the button on top of the filter after it's all back together ?
