Fuel pressure check gauge tools

Yes absolutely. There are low pressure testers and then there are high pressure testers. You can use a low pressure tester on a high pressure system as it will blow up, if you use a high pressure tester on a low pressure system it most likely won’t give you a reading. Plus there are some systems out there that you will need to make fittings for the tester to operate as the kit will not have the correct accessories.
There's such a difference between fuel pressure between carbureted engines and injected engines, that for accuracy, you should use different gauges to check pressure. Carburetors run about six psi, so a wide range will show about zero to ten. Injectors run about forty to sixty, so a gauge will show about zero to 100. A lot of people just get a zero to 100 gauge, but that's tough to read the low pressure for carburetors.
