JV...I see you have done the Hutch mods. What kind of filter are you using before the pump since you removed the screens?
Reason I ask is because last year when I was using the cheapy 99cent filter it gelled on a day that the high was 12F. With out the mixing chamber mixing warmed fuel with the cold from the tank the lines will gel fairly easily on the fly from what I was told by a vendor.
Installed a heated pre-pump filter and have had no problems with fuel pressure even on the mornings it's been single digits. I'm running B20 through a 2 micron filter too!
