Default RE: Air bubbles in fuel line ?

Before you try to fix anything, let's try to find out if there's a problem.

Lots of guys say "I have bubbles in the fuel line"

Ok, so we ask, "How big are the bubbles?"

And the answer is, "Tiny"

Well, obviously you can't fit a big bubble in a fuel line, so "Tiny" is not the best description.

So let's analize a little further...

When the engine is running, do you get (Referring to the picture):

Fig. 1 - A small amount of foamy bubbles the pool to the top of the fuel line and either remain still or move very slowly.

Fig.2 - Asteady stream of tiny bubbles the flow with the fuel

Fig.3 - A LOT of bubbles that move rapidly with the fuel
