I'm buying the Autometer boost/vac and fuel pressure gauge. for a Vortech system. should I get the Full sweep electric gauges or the mechanical.


also there are two different fuel pressure gauges. Ones goes to 15psi the other to 100psi which would be best for me to buy?


Thanks for the help

a) boost/vac , use full sweep
b) you must use the 100psi gauge, typical psi on the Z > 50psi.

autometer full sweep electric is great..

It Auto zeros each time you start the car and recalibrates to zero regardless of any changes in barometric pressure or altitude.......
It has to have a "key hot-hot while cranking" source to work right or the zero will zero itself to the vaccum created by the engine when it is being started...........
