Worked perfectly

Edit: Pressure drop was not from this check valve. The injectors were leaking. The check valve appears to work well. Everything after this line is from my original review (that was mistaken).This item did fix my hard start issue (one star) and it does not externally leak (one star) but it does not hold pressure.The product claims to hold up to 6 bar (87 psi) but had bled away all pressure in the system after 2.5 hours.start 53 psi10 min in 41 psi20 min in 35 psi30 min in 27 psi40 min in 21 psi50 min in 16 psi60 min in 12 psi70 min in 9 psi80 min in 7 psi90 min in 6 psi150 min in 9 psiIt id hold enough fuel in the fuel rail to start up the vehicle on the first crank after letting it sit overnight but does not do what it advertises.

I tried two different sizes and both leaked gas at the o ring where the two pieces screw together.

Bought this set to use on the fuel line of a street rod that I’ve had. Works great for a couple weeks then somehow the O-ring went bad and it was squirting gasoline all over the engine. I took it off. Saw what was going on threw it away
