A question about the fuel module bracket / vapor separator chamber operation.

[Jquest]

The other day I was checking my lines and doing some things to make sure I'm not getting air in the lines. What I noticed is...where hose goes connected to the fuel moduel bracket( 90* screw on plastic connector)...there is still air in that chamber. Since I run 50:1...the gas is a little dark. So...I can see through the plastic and see where the level of the gas is going into the chamber. It looks like there is still air in there. I thought the vacuum operation was supposed to suck all the air out? I know it works...cause I bought a new vapor pump about a year ago and I can feel the pulses when I put my hands up to the hose that goes into the carb cover. Am I getting trapped air in there or is that(gas level) slowly supposed to come up and fill the chamber as you accelerate?

It is normal to have some air trapped in this chamber as it is also where the fuel filter is located and prior to delivery to the vapour seperator. This is where any trapped air/vapour is seperated allowing the liquid fuel to travel to the vro pump. This pump also injects oil into the fuel, from a remote oil tank. You shouldn't need to be pre-mixing the fuel as this will cause extra carbon to build up on top of the pistons and in the rings.<br /><br />Hopefully this helps.

thank you for your answer. I forgot to mention. I removed the vro and run 50:1 with a fuel only pump.
