fuel filter flow direction
So, I'm well aware that there is an arrow on the fuel filter that designates which way it is supposed to flow. However, when I got under my truck to change it the other day, there was a larger line, and a smaller line running side by side. The fuel filter is in the smaller line, as I'm sure everyones is. Isn't the small line the return to tank? And if so, I thought the fuel filter on these was in the feed line, so it could be filtered before getting to the injectors. Will the truck still run if the filter is instaled backwatd? I would think so, just not very well.
So if the fuel filter is in the return line, then obviously the arrow should point to the rear of the truck when installed, correct?
