It’s amazing that Riff Raff has so many specific parts to make my vehicle run forever!!!

I've spent a lot of money at riffraff, love their products! Only gave this a 4 because one of the fittings had a nice gouge on the inside, I'm surprised it doesn't leak, at least it hasn't thus far.

I kept fighting a leak and then decided just to replace the hose and fittings. FIXED! But, 3 years later I had to replace the HPOP fittings again. Guess I'm good for another 3 yrs.

I received some damaged parts, but Clay responded to my email wishing 8 hours. I told him I needed the parts by a certain date. No questions asked he sent out the new parts to be received on that date. He made it right. Outstanding.

Was very happy with the valves was a little worried about going from check valve to none but was very happy with the valves can't tell different between the two as far as starting.

For those who are modding their fuel supply system don't overlook this valve. Larger opening for fuel.

These fit great, and after driving my truck for a few weeks in Ohio winter weather, I have not had any issues with removing the check valves from the stock fittings.

After rebuilding the HPOP fittings for the last time I decided to just buy New one's. These worked GREAT, no more leaks and installed quick.
The initial start was long, but after driving 100 miles, all the air worked out and it starts maybe 1/2 second longer than before.

Great addition!!

O-Ring on original valve was gone and it would fill the valley in 5 minutes with oil. Cheaper than anywhere else online. Buy the Quick Disconnect from here too, its also cheaper than anywhere else online and has a bottle opener on it. The link below is the install video that helped me with it. 25 ft lbs of torque on these guys!! Nothing more!!
