The Fuel Filter Manager, or FFM, is an assembly atop the back of a 6.5L GM/Detroit diesel engine that houses the filter filter. While GM advises replacing the filter every 30,000 miles, we usually recommend every 15,000 miles. The fact that the 6.5 diesels are all very “vintage” engines with a lot of kilometers on the odometer and a lot of silt in the fuel tank necessitates more regular filter adjustments. Fuel filters for these engines are inexpensive, and your engine will always benefit from more frequent maintenance.
On a 6.5 diesel, how do you bleed the fuel system?
When it comes to bleeding, all you have to do is crank the engine for 15 seconds at a time, followed by a one-minute starter cooldown period, and it will self-bleed. While bleeding the high pressure side, I prefer to crack one injector line loose; it helps to speed things up a little, but it’s not required.
What is the range of a 6.5 turbo diesel engine?
6.2/6.5 Life expectancy is around 300-400K, with many being replaced before they reach 100K (catastrophic failure, not wear out) and a few reaching 500K, even 750K+.
Why does my 6.5 diesel continue to stall?
THERE ARE TWO PRIMARY CAUSES. The PMD is the first and most common (also called FSD). Another option is to use the Optical Sensor included within the pump.
What is the best year for a 6.5 diesel?
Volume I of The 6.5L Turbo Diesel contains essential 6.5L diesel-related articles, tech columns, and product evaluations published by The Diesel Page between 1996 and 2001. (plus a newer article on turbochargers). We’ve “cherry-picked” all of the best pieces produced and published during the last five years and compiled them into the volume you see here, which has been updated for 2018. This is a fantastic collection of 6.5L Turbo Diesel and vehicle-related information written by enthusiasts for enthusiasts. This volume has 36 articles that cover all GM 6.5L diesels made between 1992 and 2000.
This new and updated second edition now has glossy full-color photo-quality front and rear covers (real front/back covers seen above), as well as a completely updated, reformatted, and reworked interior with 136 glossy B/W pages filled with 293 updated photographs and graphics.
The sections in this full-size 8-1/2″ x 11″ volume are beautifully produced and elegantly bound, and they cover the basics: performance and maintenance. Information that will assist you in improving the performance of your 6.5TD and learning more about the best service practices will never be out of current. We don’t sell any of the products covered in this volume, and we weren’t compensated to include any of them, so you can be sure you’re getting the most accurate and unbiased information possible. Our goal is to assist GM 6.5L diesel owners in getting the best outcomes possible.
The 6.5L Turbo Diesel engine was initially used in GM’s 2500/3500 series pickup trucks in 1992. Looking back, we now know that the 6.5L’s strongest years in terms of performance, customer satisfaction, and sales volume were 1992 and 1993. The 6.5 sought to compete with Ford and Dodge from 1994 onwards, but it needed support. This is part of what this book is about: starting with a factory 6.5 and working with the aftermarket and skilled 6.5 enthusiasts to identify ways to improve performance, increase cooling efficiency, and solve the reliability issues some owners have had with their vehicles. Owners have been able to be satisfied with the 6.5’s performance and car ownership in general thanks to the information contained in this volume.
This section begins with an examination of the 6.5’s introduction and the reactions of the automotive press at the time. We’ll teach you how to make your 6.5 perform like it should have right out of the factory from there until the end of this volume.
This volume was changed for the first time in 2008, and then totally updated and rebuilt in 2018. (the beautiful version you see here). We added an updated piece regarding turbochargers during the initial update because turbocharger selection is extremely crucial when it comes to 6.5L Turbo Diesel performance. This essay on turbochargers answers a lot of issues concerning power, cooling, and dependability, and it expands our understanding of the 6.5L Turbo Diesel, allowing it to compete in the new millennium.
We at The Diesel Page hope you enjoy this book and, most importantly, that you learn how to enhance your 6.5 in any or all areas where you believe your truck or Suburban could use some work. We want you to be successful. TDP

On a 6.5 diesel, how do you test an injection pump?
Start the car to test the lift pump. Allow petrol to drain from the line into a container by opening the T-Valve for at least 30 seconds. If the engine dies or no gasoline flows out of the line after 30 seconds, your lift pump is broken.
Is the General Motors 6.5 diesel engine a decent engine?
I’ve had no big issues with my 6.5 in the two years since I bought it. It’s a good engine if you’re knowledgeable with the frequent problems that come with it. Allow it to breathe and move the PMD, and you should be fine. You mentioned that you’re looking at a 1997, and it has two thermostats, which will help with any cooling difficulties.
Is a 6.2-liter diesel engine superior than a 6.5-liter diesel engine?
It is entirely dependent on your objectives. The 6.5 is for those who want to go fast and tow large loads, while the 6.2 is for those who want to achieve the highest possible fuel mileage on the smallest possible budget.
On a 6.5 Diesel, how do you test a PMD?
Touch the pink wire terminal of the PMD connection with the probe of the test light. The light should turn on when the ignition is turned on. If this isn’t the case, troubleshoot the circuit. Next, make a solid connection between the CLIP of your test light and one of the positive battery connections.
On a diesel engine, what is a PMD?
So, what exactly is this PMD? Pump Mounted Driver is the abbreviation for Pump Mounted Driver. An FSD, or Fuel Solenoid Driver, is another name for the same item. (One is Stanadyne terminology, the other is GM terminology.) It’s a “black box” roughly the size of a deck of cards positioned on the injection pump’s driver’s side.
When was the 6.5 diesel released?
In 1992, the first 6.5 GM diesel was introduced to the automotive industry. The 6.5 diesel was made available in various other GM applications in the years following this preliminary showing. The 1995 6.5 GM diesel was designed with fuel efficiency in mind. The 6.5 diesel, on the other hand, did not achieve much favor due to its lack of power in comparison to other diesel engines on the market at the time. In order to gather experience, GM offered a turbocharged version of the 6.5 diesel.
