Quick delivery, easy install. Might have taken me an hour but no more. Great quality lines, all together an easy project that will now last he life of the truck which is way more than I can say for the original lines from Ford.

Fuel lines Worked nice but did not work with the RiffRaff CCV fuel fittings so ended up not using those after purchasing them .

Installed these after my passenger side factory hard line failed. Superb quality over the factory hard lines. They were a little tricky to get installed due to limited access on the back side of the passenger cylinder head but not impossible. Well worth it in my opinion.

I never would have thought how bad this mod needed to be done but after taking off the pen lines I knew this was a mod everyone should know about! My ‘02 F350 had to have been starving for fuel considering how every o-ring in both lines had come apart, in pieces against the screens on each line hindering needed flow to each head. Anyone up fitting a truck should put this mod at the top of their list!!

So glad to see parts made in the USA! Always been a customer of Riffraff and always will be. Quality you guys produce is unmatched as seen in this line kit. If you want to get away from your small, stock hard lines this is the kit to go with.

Huge improvement over oem. Threw these on when installing some new injectors and the truck runs out great now.

Great quality kit, nice to see usa made stuff. Deletes the check valves in the heads and replaces your junk stock lines all at once for a low price. I did the spring kit at the same time from you guys. No leaks, and it looks great.

What a well made product, easy install and really cleans up your engine valley.
