Review on Standard Motor Products FJ504 Injector by Larry Willis

There may be a problem with the block I bought for my 97 k2500 as the cylinders are now flooded with fuel causing a water seal. Will be updated if there is a product or installation issue. It was only installed within a week. Update: After additional verification. The fuel pressure regulator only failed after a week. My 5.7 Vortec had a valve body and I had to haul it home to drain the fuel and the new oil I just changed. As you can see, the 6th cylinder intake pipe is filled with fuel. I hope this isn't a common issue with these updated spiders, but oh my god it hurts to do more work the second time around. Was also wasted seal drain pipe. Update #2: The problem wasn't with the product, it was a pinched return line on the pump causing over 100psi of pressure which in turn caused the regulator to shoot fuel directly into the intake ports. After this was discovered and I installed a new regulator it has been working great ever since.
