Actron CP7838 Professional Fuel Pressure Tester

Actron seems to have changed the storage bag for this product. I could probably get 2 gauges + acc into the bag I got and there is a clear window on the bag so you can see what's inside.

I have several Actron test products and they are far superior to the junk you find in the chain auto parts stores. No flimsy plastic parts that break off at the slightest provocation.

P.S. If you have an import you can get 3 additional banjo adapters sold directly by Actron. I found 2 of them here on Amazon. And they don't gouge you on the accessories price like many other manufacturers.

This fuel pressure tester worked great for me. I was able to connect it to the test port on my fuel rail and test pressure within literally about 2 min. I didn't have any help, so i was able to lay the gauge down on the windshield and watch the results as I ran several tests from the drivers seat. Since the gauge has a rubber bumper around it, it stayed in place even when the fuel line pressurized. I did not have any problems with leaks at the fuel pressure release button. This tester confirmed I need a new fuel pump. I think it is the perfect balance of price, quality and functionality for the DIY'er.

Got the job done for me. Confirmed I was leaking fuel pressure after shutting off the engine (causing hard starting) and allowed me to determine where it was going, which turned out to be the last place I would have expected. It cost half what the dealer's diagnosis did, who mis-diagnosed the problem. Did not have the problem of leakage around the pressure release button that another reviewer mentioned. However, if you use the T hose adapter I'd recommend putting a wrench on the fitting to make sure the two brass parts are tightly screwed together before using it. I had a bit of a leak from there that disappeared once I cranked up the tightness a turn or so. If you use the T fitting take a look at it and you'll understand what I'm talking about.

Professional level, well made product that does exactly what it should, give solid performance. Wide assortment of adapters is very useful if you work on more than one car. Only real negative is minor. Storage pouch is a little small. Tough to get gauge and all the accessories into it. No big deal.

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.
