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
