Riffraff Diesel High Flow Banjo Bolt for Ford 7.3L 94-03

Why bother trying to drill out your stock pot-metal bolts in the cylinder head and break them off while reinstalling? Not to mention a larger hole does not necessarily equal more flow, and can create an incredible amount of turbulence that actually reduces flow to less than stock.

We have engineered a high flow fuel bolt using StressProof® Steel that offers the highest flow possible. By combining a patented, high-end steel with precision flow/port testing we have been able to reduce turbulence, raise flow, and increase bolt strength all at an economically minded price point. Unlike other copies we make our banjo bolts 100% in the USA for quality you can trust. 

- Made from Patented StressProof® Steel
- Precision machined low restriction ports
- USA Made Viton Oring Leak-Free Seal Included
- 100% Made in the USA

Quantity of 1= 2 banjo bolts


1994-2003 7.3L F-Series, E-Series, and Excursions on the head.

    Simple Install

    Posted by Unknown on May 2nd 2021

    Not hard to install, just a little tight on space. Noticed better throttle response as well as smoother idle. Overall would recommend.

    Installation was simple. I also believe the truck has a more noticeably improved idle

    Restored Fuel

    Posted by Sam on Apr 4th 2021

    After finding that my oil pressure was fine, I decided to get these. The girl was starving for fuel! Runs so smooth now, idles fantastic, and can feel the difference in the throttle response!

    Worth every penny! Also got the stainless RRD flexible feed lines to go along with these!

    RiffRaff makes some seriously high quality stuff!

    Banjo bolt upgrade

    Posted by Josh Pinkley on Feb 13th 2021

    They were quality. Pain to get at the rear one. Haven't noticed much difference but I need to do the hutch next. I think that will make the banjo bolts more noticeable.

    Good quality

    The quality is absolutely phenomenal on these, and the design is really nice as well. They are a pain to install, but only because of where they’re located on the engine. As for performance, I can definitely feel an increase in the throttle response.

    Did mine as just a support mod. Pretty easy installation. Noticed a slightly different tone. Didn’t notice much performance gain. No matter, definitely worth the $50. Great product
