ok so i went to buy a fuel pressure tester/guage........i really want to diagnose my car and get it on the road as soon as possible.....but i cant drive it otherwise id take it somwhere

so i go to buy one and on the back it says GM vehicles up to 96

whats the deal its the only guage any store has and my car is a 97
will it work on my 97 or is there a special one or somthing to buy for vehicles newer than 96??

thank guys im really aggrivated and well u know how it is when i hadnt driven ur car for a while...im just venting
