Great Moneysaver
The modern fuel injection systems are great! Untill something goes wrong. Then you find out that the problem can be caused by any of the many parts involved. In my case, bad start caused by: clogged or leaking injectors, faulty pressure regulator, clogged fuel line and/or filter, fuelpump pressure and more.I will not write down my experiences with the local stealership, suffice to say that if they touch a vehicle I own ever again I will call de cops!After eliminating electronic causes I replaced the fuelfilter (cheap, easy and about time anyway). When that didn't do the trick I checked out the carforums online for my model/year and found a host of possible causes for the problem. I also found that the single one thing needed for a proper diagnose of the fuel system was a fuel pressure tester.Found this one at a price below that of any of the fuel system parts.It absolutely worked for me. I was able to pinpoint the problem within minutes...

Good Guage
This is a good guage for the home mechanic. Kit has adapters for just about any vehicle out, you can even splice into a rubber fuel line if the fuel rail adapter you need isn't in the kit. My particular vehicle is a Lexus RX300 which is basically a V6 toyota with Lexus decals, this kit came with the proper banjo bolt adapter and sealing washers for me to do the pressure test. The guage is encased in rubber so you can lay it face down on the windshield and check the pressures from inside the vehicle without it sliding down the windshield. The guage also has a pressure relief button which is nice to have when your done with your testing. Two things I would want you to do before using the guage for the first time. 1 remove the black test line atached to the guage and wrap the threads in teflon tape. It's worth 25 seconds of your time to prevent a leak. 2 At the other end of the same black line is a brass fitting, look inside it and you will see a rubber o-ring give it a shot of WD-40...

not bad but be careful
The first one I bought started leaking raw gasoline from the gauge while I was testing the pressure on a running car! Very scary. My son was just coming out into the garage and I yelled to get back in the house while I ran to turn off the engine. Luckily, nothing happened but it could have been a disaster. It may have been a rare manufacturing defect but who knows how good the quality on these things really is? I ended up getting a replacement for free and that one has been just fine. No problems. However, the first experience still haunts me. So when you first use one of these things, have someone in the car ready to kill the engine and keep a very close eye on the tester for at elast the first 10 mins of use.
