For not much more than the cost of two secondary fuel filters you can install a pressure gauge. That tells you when the fuel filter needs changed out.

Saving the cost of the filters if changed out when not needed. Plus warning you of other problems starting to develop. This is more diesel oil specific than alternative fuels usage.

But Fram spin-on filters are generally not in the same league with the likes of Wix or Purolator. The Purolator L43056 diesel oil filter, however, is usually an import of poor quality.

The best of the best for a 616/617 are the Baldwin P102 filters, they are made in USA, and have a dual-pleated element design instead of a canister of sweepings or cotton string. They are pricey ($13 in bulk or about $16 individual), but they are extremely high quality. I have been using them in all our diesels for years. Just need to find one for the OM601.....

Edit: they DO make one for the OM601 and 602: its the P7196

I'll have to order some...

Working late one evening on my 240D, I needed fuel-fiters. Pep-boys was out of the in-line unit but stocked a Purolator spin-on for $14. But at least it turned out to be a reboxed German Mann. So I headed next door to Advance Auto for the in-line filter and they also had the same Purolator for only $8. I was going to buy it and return the first one until I opened the box and found a plain, white filter, identified only with the words "made in China"!
Normally, I buy the Knecht spin-ons from a local indie MB parts place for about $6.

Happy Motoring, Mark

I have found that comparing the pressure applied by the right foot to the speedometer tells me everything I need to know. When increasing pressure equals constant speed, replace fuel filter.

Baldwin P102 = Hastings LF380 (Granger wants $13.50 for them in My area). Baldwin/Hastings are parts of the same Company. For some reason the Hastings version of the Filter cost less (I have some Hastings filters) and they seem to be slightly more available.

I Emailed Hatings and they Hastings and Baldwin Filter have the same Microns of Filtration.

No on has done much research on the Oil Filters for the over 1985 Diesels.

I was thinking the same. If the Filter is starting to restrict the Flow it will show up at high speeds first. You are not going to be able to see under the hood to watch a gauge.

At idle speed the gauge could show a normal pressure. I might be that reving the Engine might show on the Gauge when the Flow is restricted.

I think the Gauge is better used after you change the Fuel Filters to tell you if your Fuel Supply/Lift Pump and the Fuel Pressure Relief/Overflow valve are working OK.

Also avoid the Purolator and STP Oil Filters for the 617.952. The both appear to be the same Indian Made Oil Filter.

I took one apart and the worst mix of Cotton Jin in any of the Oil Filters and the bypass section and the Metal Tube in the Bypass section was not sealed at all on the Bottom. Just a Metal Tube against the Metal part of the Filter.
There is pic of the above in one of the Threads.

Have you ever taken one apart? they have a little pleated filter that is about the size of a c - cell battery...... very restrictive , and very expensive. I have made a little adaptor that allows me to use a fram 2870a oil filter that is 3 times the size and 1/3 the cost, they are 3.77 at wally world and probably filters finer that those fuel filter because its an oil filter.
I took one of these..... oh well this forum wont allow me to upload pics (which pretty much tell the story) which is strange because I uploaded pics for my last post exactly the same way. I guess I will try later. In essence there is a gas line part that you get from home depot and then tap it to a 14mm x 1.5mm which you can get the tap from vendors on ebay for about 6 bucks for 2. Then you cut this part off and the screw that you tighten on the fuel filter will thread onto this and you tighten it down now the fram 2870a will spin on just like an oil filter, dosent leak because it is about the same od, but it is much longer so it flows alot better and lasts alot longer. Yep if I can contribute to a little payback for these companies overcharging us for so long, I am happy about that

Thanks

Just to be sure it's mentioned...
the fuel system is fairly complicated, and tolerances and materials of construction are tight, and delicate.
filters designed for hot large particle oil are Totally insufficient to protect the fuel delivery/injection of a diesel motor.

as mentioned, the diesel FUEL filters are designed to BLOCK water, as well as catch any fine particles that collect or grow in your or the station's fuel tank...
an oil filter is not.

Plus, a fuel filter should never feature a bypass valve.

Unfiltered oil is better than no oil. The same does not apply to fuel.

I would like to see a write up about your belt drive Mobius.

not really, like if you are not at home for example, especially when you are in a place like Baltimore

I know about sticks and bugs oil filter. I still love the concept... "i only use genuine Mann oel filter, German make!" "oh, cut it open and look inside..." "aaaaah oh! sticks and bugs!!"

Problem is, wherever you are, you won't have a clue that your bypass valve is open. And you might be in Baltimore when your IP gives up the ghost, thanks to all the unflitered fuel it's been drinking for who knows how long.
