The Perkins 4.108 engine, both the marine and industrial versions, has been around for a long time. Unfortunately, parts are becoming harder to find. The Perkins 4.108 predecessor, the Perkins 4.99 and the Perkins 4.107, also referred to as the Westerbeke 40, are even older and those parts are even tougher to find. But because we’ve been in business for a long time (since 1916) we can help identify your Perkins lift pump.
To support people like you, we stock our warehouse with Perkins engine parts, including hard to come by take-off parts. Take the fuel lift pump, a common maintenance item for a diesel engine. Foley stocks both the lift pump for the Perkins 4.99/4.107 as well as for the later Perkins 4.108. We also have the high pressure fuel injection pumps and can help you identify the right injection pump for your engine.
Because the lift pumps are a high mortality item and there were several versions that are not interchangeable, we want to point out the differences to help you order the correct lift pump. As you can see from the photos below, the early Perkins 499/4.107/Westerbeke 40 pump has a two bolt mounting flange while the later Perkins 4.108 has a four bolt flange. Moreover, the early pump has a long rod on the side of the pump. The late pump does not. These can help narrow down the pump you need, but if you are still not certain, give us a call and we can help you identify the correct pump. One piece of information that will be helpful are your engine serial numbers and for the earliest engines, Perkins didn’t always follow the same numbering convention, but take a look at our tech tip on Perkins Serial Numbers to find out just where to look. If you prefer, we prepared a video.
