Fuel Tank Return Line

Post by **west E** » 15 May 2007, 18:12

Just staring to take out my fuel tank, as i'm reading the wiki and haynes it states i should have a fuel return line. I don't!! the pipe is coming out of the tank about 4 inches then is blocked off. Should i have a fuel return line and if i should where does it connect to at the engine end of things. Sorry forgot to says its a 2ltr Aircooled.

cheers

The return line usually comes from the carb (and is usually opposite the supply line).

i have dells drla's 36, not sure if they have a fuel return.

i did notice when i had the orginal carbs that fuel sometimes seem to come out of the sides of them, how a fire didn't start i dunno.

cheers

You really need the return line connected. The pump will be pushing more fuel than your engine needs and if it has nowhere to go it may soon find a way out, especially when on the motorway.

the 2 litre Aircooled doesn't have a return line. not that anyone'll believe me i imagine.

I believe you wullie. I bow to your knowlege. I had a two litre 77 bay and I am sure that had a return line but it was too long ago so I'm not gonna argue. I really know very little about the T25 air dryers.

if yer bay was an american fuel injection spec one then you would be right. carb euro 2 litres and any other type 4 injined bay don't have return pipes either.

No, not US spec, a common twin carb jobbie, so probably no return line. I stand corrected.
