RE: Gas Engine Filters, Where, Which is best?
A good gas carb can handle up to about an 8" void of fuel in the line before the next influx of fuel is obtained, but rpm stability suffers badly. There is no reason for this when a felt filter only needs to make contact with the fuel to provide a constant fuel supply with virtually zero bubbles in the supply. There is also the fact that a felt filter making only that same basic contact with the fuel will sump nearly 100% of the fuel in the tank before the engine runs out of fuel. With most all other the pick up must be fully immersed in the fuel resevoir to function at all.
However, if some feel a pick up or filter needs to have a fancier appearance to suit their egos they always have the option of using the lower quality products. Eventually they will learn.
