i have the above ready to be installed. came with instructions. i saw a post a while back that the directions are misleading. i dont have in front of me but i recall my unit has 2 springs. one like 4-20 lbs so obviously will use that for 7.4 L TB install. current stock reg removed and capped. now i recall seeing 4 portss around the body and one on bottom. does the ports(1) around the body receive the return line from TB thus provide the back pressure so to speak(13 lbs) to pressure the system. the bottom one on reg is the return to fuel tank i assume? if so any of the other (3) ports could receive a FP gauge rather than be capped off? or do i have this backwards?

 

Which one do you have?

 

AEI-13301 bypass style 3-20 20-65 depending on spring...

It doesn't have a dedicated port for the fp gauge? I can't tell from the pics.

I have an Aeromotive reg, but its 13101. It has a dedicated port for a fp gauge.

I ran the return from the TB to one of the ports on the side of the reg body. The bottom port is plumbed to the return line.

Email your question about using one of the other ports for a fp gauge to Aeromotive. They're good about answering.

 

13101 ? that is 30-70 lbs FP rating. i run 13 lbs. i was first going to plug off the other three BUT thought if return line shows less pressure, the other 3 ports MUST show the regulated pressure to the TB. they all feed equally from the same area. After all the REG is downstream from the TB. thanks for the tip to contact Aero. will send them an email.

 

Yep. See my sig.
