donradclife If your Perkins filter mounts with the open end down, you need to make sure that you use genuine Perkins filters or that the filters you use have an anti-flowback valve, which not all the generic cross-references do. Otherwise the oil will drain out of the filter when the engine is off, and it takes too long to build oil pressure when you start the engine.

OceanFreedom I buy most of my Perkins stuff through S&W Desiel S&W Diesel, Inc. Perkins Engine Sales & Service
These guys are a great resource and will bend over backwards to help you out.

Even if you do not buy anything from them they are a good resource.

SimonV Perkins 4.108 are used the world over, a majority are in farm tractors, pumps and generators. I just picked up 4 from a farm supplies at 1/3 the cost (made in Malaysia) but perkins specs. Ryco Z103 wereabout $30 here in Oz.

I spent $7.83 for the large perkins oil filter at a diesel truck parts store here in Maryland.(JG Parks and Son) The fuel filter was about the same price but was not the Perkins name. Haven't checked the online prices yet, but will go back to the Perkins brand on the fuel filter this spring assuming that I can buy it online and/or the truck parts place starts carrying it again.

Careful with FRAM!

Fram (the orange ones) used to be the "standard" for spin-on L.O. filters - I have read of issues lately with these filters - Google same and check - so they don't seem to be as good as they once were. Things like the non-flowback valve, the relief valve (these are normally full-flow filters, and if they plug up for some reason, the relief valve allows oil to bypass the element and not starve the engine for oil), and the internal element end caps are all critical. Not to mention the filtering media itself.

The Fram PH2821a should cross to a WIX 51806 (double check me on that) - WIX has gained quite a reputation for quality filter construction - they make the "gold" NAPA filters, and are also readily available at auto part stores and Wally World. DON'T spend crazy money on "Perkins" brand filters, but DON'T risk your engine on cheapies either! Happy Motoring!

lancelot9898 I buy my oil and fuel filters for the Perkins 4-108 from a local diesel truck parts shop. This last time they did not have the Perkins name brand fuel filter so I went with the equivalent, however I do like going with the Perkins name brand instead. The Perkins oil filter has two sizes and I've been installing the larger of the two for the past 5 years or so. The fuel filter that I replaced last year is different in internal construction than the Perkins brand and this year I'll try and return to the original brand even though it may not make a beans worth of difference. The Trans America website ( ) has most Perkins parts including gaskets which are hard to come by and I'll be ordering from them soon.

SanDiegoChip I stopped at Admiralty Marine on Rosecrans and picked one up but think I will return it. It is a really good filter for $21.00 though.
We will be repowering in a year so no need for such a nice filter.
Napa will work fine.
