The Diesel Podcast

Diesel injector sizing can get confusing fast. Percent over, hole size, liters per minute (LPM)—what do these ratings actually tell you, and how do you know which injectors are right for your build?

Lenny Reed from Dynomite Diesel Products joins us to break down the different ways diesel injectors are rated and why comparing injectors isn't always as straightforward as the numbers make it seem. We talk about what “percent over” actually means, flow ratings, injector sizing, and why choosing the right injector needs to match the horsepower goals and overall setup of your truck.

Whether you're building a Cummins, Duramax, or Power Stroke, understanding injector sizing can help you make better decisions before spending money on your fuel system.

Modern diesel engines generate a lot of heat, and keeping that heat
under control puts a huge demand on the cooling system. But how often
should you actually change your coolant, and what happens when you leave
it in too long?

Rislone joins us to talk about diesel cooling systems, proper coolant
maintenance, and some of the common mistakes truck owners make. We
discuss corrosion and contaminants that can build up over time, how
coolant condition can affect heat transfer, best practices when changing
coolant, and why maintaining the cooling system is so important on
modern Cummins, Duramax, and Power Stroke engines.

Not all diesel fuel filters are created equal—and choosing the wrong one
could affect your truck's performance, reliability, and even the life
of your fuel system.

On this episode of The Diesel Podcast, we sit down with S&S Diesel
Motorsport Chief Engineer Ian McGiffen to discuss what separates a
quality fuel filter from the rest. We cover filter media, micron
ratings, filtration efficiency, common marketing claims, and why two
filters that look nearly identical can perform very differently.

We also dive into a common failure point on the 6.7L Power Stroke: the
factory plastic fuel filter housing. Learn why it can crack, create fuel
leaks, cause drivability issues, and why many owners are upgrading to a
more durable solution.

What diesel parts are actually worth buying? In this episode of The
Diesel Podcast, we bring together Fleece Performance Engineering and
Domestic Diesel, a California diesel repair shop, for a unique
conversation about the parts they see every day and the problems truck
owners face.

We discuss CP3 conversions, 6.0L Power Stroke replacement cylinder
heads, electrical pigtails, common diesel truck failures, and how
quality replacement parts can improve reliability. You'll hear both
perspectives—the manufacturer designing the parts and the repair shop
installing them on customer trucks.

Whether you own a Cummins, Duramax, or Power Stroke, this episode is
packed with practical information to help you make smarter decisions
when upgrading, repairing, or maintaining your diesel truck.

Not all diesel parts are created equal. In this episode of The Diesel
Podcast, we sit down with Snyder Performance Engineering to discuss the
growing problem of copied and counterfeit diesel parts entering the
aftermarket.

We break down how legitimate American-made diesel components are reverse engineered, copied, and sold at lower prices, why quality often
suffers, and what these knockoff parts can mean for the reliability of
your Cummins, Duramax, or Power Stroke. We also discuss how counterfeit
and low-quality replacement parts impact diesel truck owners,
manufacturers, and the aftermarket industry as a whole.
