Is would think there is a regulator built into the pump. I'd start by checking with Walbro.

 

from what i have read and herd 14-15 is more than enough and actually anything more than that is actually more harmfull than good

 

Here ya go Bob ... straight from FASS themselves ...

would you by chance have a the filler neck return line fitting that i could purchase?[/align]Part number is RM-1002 (Black in color for the Dodge). Any FASS dealer can get it drop shipped to you.

 

I went to the hardware store and made one that fits on the 3/4" vent tube. Works great and only cost $6 to make. Check out my other post with the link to all of the pictures.

 

Yeah, I saw it. AWESOME write up !!

Just keep that part number handy in case running all of that extra fuel down your vent pie causes you problems ( don't see how it can, but you never know ). I put that filler neck adapter in very easily without even having to drop the tank.

 

My 90 gallon tank goes through the vent pipe and I've never had any problems with it in the 3 years that I have had it. I'm already over budget on that project so I won't be buying any more parts unless necessary.
