Here's my deal. I could spend 200$ for a areomotive low pressure regulator, but then have to turn around and change it out to go FI.
The 13222 regulator is supposed to be for very low pressures , but yet not a bypass.
I might just do the run again and this time carefully monitor things. Might just take a tweek of the float levels to be good.
Probably go back after installing new HG. Might also punch out the chokes too.
As far as a bypass and large enough return, I'm planning on using the evap line that is on the drivers side that goes back to the vent box. It's a 1/4" and should be big enough for a return for our engines and more.
