Do you have a fitting on your heads?
On my intake, I don't have a port to install a temperature sending unit. The only thing available is to run some sort of inline sender from the dump. There is a single -12 dump that comes off the front of the intake. There are also two -6's that are tapped into the back of the intake and an elevated hose, looped to get rid of air pockets. I was thinking of changing this, by adding a T and reducing down to a -4 and dump that also. So my questions are:
#1 Where are you getting your temp reading from?
#2 Would the temp reading be higher at the back of the block, or the front?
Do you have a fitting on your heads?
What are you running?
