Fuel Pressure Tester
Is this a sufficient fuel pressure tester for a 1994?

Looks the same as stocked by any Discounter and as long as you just checking static pressures, it will work fine for allmost any vehicle out there. For an injector leakdown test the increments are too small to notice minute differences in pressure, but few DIY's buy the equipment to energize the injectors for that sort of testing.

Spend a little more and buy an electronic gage: 2-1/16" Autometer.
Electronic so you can use gage inside car. Leave gage inside packing box and move from car to car. Connectorize it and use as a test gage. Perhaps most important aspect of fuel pressure is observing it WHILE driving !!!
You'll still need an adaptor to connect rail FP to gage sender - 1/8" NPT. Available many places. I also sell the adaptors and/or on end of teflon hose etc. See my catalog page 32.

You want a gauge where the number you are measuring is mid-scale and not close to either end. This is where the greatest accuracy is of any gauge. For our LT1, 30 to 50 is the range your interested in. if you were working on a LS engine, they run at 60 psi.
My gauge goes to 100psi. Must have it for at least 10+ years and it works just fine for the Corvette. Use it on my Silverado as well as my Jeep Cherokee. So it seems to be versatile and good for a lot of cars. These are not highly accurate gauges (with the low prices) but are just fine and used for testing to find out if the fuel pressure is there, or not, or just very low etc.
