Great quality and price
This is by far the best fuel pessure tester you can buy without having to turn to the other more expensive brands of tools. I'd give it a perfect 5 stars if it wasn't for the fact I had to buy a couple of extra fittings you can find here to better suit what your working on.

Fuel pressure tester works good for 87 K5 Blazer
I bought this kit to check fuel pressure on a 87 K5 chevy blazer with TBI fuel injection. This kit has the correct fitting to check pressures at fuel filter or at the TBI unit on the engine. Worked great.

OTC has usually had a good name.
The fuel pressure tester came in a good plastic case. Looks like everything is there and it looks quality. Have not used it yet but it should work just fine.The only thing that I did not care for was that by the time shipping, taxes and duties were added I pay 2x the sale price.$113usd +$35usd =$149usd convert to cdn$=$190.93cdn$ + border duties-$29cdn = $219.93cdnIt was quite a shock when the final bill was tallied. Make sure you check for hidden cost before you press the button.This would not apply to American buyers.

Having the right tool makes the job easier
Use this product to test the fuel pressure on a vehicle with a TBI fuel system to save me a lot of time and money.

Performs great!
This gauge has performed well and is accurate in readings. The discharge hose is quite a handy feature too. The storage case is well made and for the money the adapter assortment is pretty broad. In this price range with these features this simply is a great buy and I would recommend it.
