Air in my fuel lines

[tconroy]

Fix it till it's broke.\\/

HA ha ha ha!!!That's a good one chef. I also run the clear line and have bubbles gurgling on mine.Looks cool!!!! Turn your petcock on prime and the bubbles will go back up into the tank.It's nothing to worry about.If you put a 1/4" fuel line on there it wont do it or an inline fuel filter. Mine did not do this till I went to the 5/16" line.If it runs fine,ride it,if it runs like crap,fix it!

Mass Flow versus Volumetric FlowMass flow measures just what it says, the mass or weight of the gas flowing through the instrument. Mass flow (or weight per unit time) units are given in pounds per hour (lb/hour), kilograms per sec (kg/sec) etc. When your specifications state units of flow to be in mass units, there is no reason to reference a temperature or pressure. Mass does not change based on temperature or pressure.

However, if you need to see your results of gas flow in volumetric units, like liters per minute, cubic feet per hour, etc. you must consider the fact that volume DOES change with temperature and pressure. To do this, the density (grams/liter) of the gas must be known and density changes with temperature and pressure.

When you heat a gas, the molecules have more energy and they move around faster, so when they bounce off each other, they become more spread out, therefore the volume is different for the same number of molecules.

Think about this: The density of Air at 0°C is 1.29 g/liter. The density of Air at 25°C is 1.19 g/liter

The difference is 0.1 g/liter. If you are measuring flows of 100 liters per minute, and you don’t use the correct density factor then you will have an error of 10 g/minute!

Volume also changes with pressure. Think about a helium balloon with a volume of 1 liter. If you could scuba dive with this balloon and the pressure on it increases. What do you think happens to the weight of the helium? It stays the same. What would happen to the volume (1 liter)? It would shrink.



To the effect that it even matters to the petcock, NO it will make no difference. However, to be precise and accurate, the length of line (in technical measurements) will have an effect on vacuum as it pertains to volume or the lack there of. 8-[

WHAT????? LOL!!!Dave, ya lost me at the gas station! I put it in the tank and the carbs suck it out, that's all I know!!!
