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.

    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

    More fuel Please.

    I have a 1999.5 and I installed the Fuel Rail Crossover FRx, High Flow Banjo Bolt, SS Braided Fuel Hoses and the HPOP crossover all at the same time. Wow what an improvement. I feel better low end power and the engine is so much quieter that before the install. I should have done this a long time ago. While you're in there, add the poppet rebuild kit and put a fuel pressure gauge on the list also.
