Here are some of the sump and then regulator carb. Demon 850 4150, 50cc acel pump in front.. Pre pump 100 micron then the system 1 is a 30 micron about under the passenger seat. Yes a 90 to return. As hard as fitting a -10 return line when I laid a -12 up did not seem realistic and I know lots of guys using -8 fine. But restriction could be possible so I'll check. Robb sent me a method to today also.
I can see the return after the carb is ideal and I know lots of circle track set uop that way but keeping fuel line on the other side of frame rail for NHRA in the bellhousing area get tight in a full body car. Regulator mount has some flex although I'm sure some vibration. My TA has dead headed regulotor bolted on the waterpump and alot of street some autocross and high 10 runs and seems to do OK over the 20 years it's been plumbed. But something to look at. Mounting a regulator on the firewall just did not seem good to me, too ling a line to the carb. No fenderwells there to use either.
So I will look at fuel but the rapid rpm increase in second still is a mystery to me.
