You'll want to run a length of copper tube off of the exhaust, this will dissipate exhaust heat and then connect a rubber or silicone hose to this to run to a map or guage pressure sensor. An efi fuel pressure or oil pressure sensor should work nicely such as those sold by Autometer or others. They're usually .5 to 4.5 v and use a late tps pigtail.
