what metal W115 240D

[cgunderm]

Does anyone have an idea what metal the fuel filter housing of the W115's is made of? Is it steel? Is it aluminum?
Thanks!

That would be aluminum, iirc.

thing is: i want to use one of them as a heated veg oil fuel filter for a two tank system, but want to make sure it's aluminum, because steel would cause polymerization of the fuel.

Is it the cartridge or spin-on filter?

Then you better get rid of the fuel lines on the body, the stock fuel tank, lift pump, and the injection pump as they all are/have steel.

The polymerization of the fuel idea is mainly for the tank(s).

Hold a magnet to it.

for the W115s, it's a cartridge that you place the filter element into, much like the oil filter cartridge in the W123s

The stock fuel tank, and the fuel lines on the body are of no concern as they will not be used to run SVO through. But the IP and the lift pump, and of course the hard injector lines are. But I suppose that polymerization happens only when there is oxygen present, so in the airtight injection system, it shouldn't matter.

I happen to have one of these cartidge assys on my desk. A refrigerator magnet wouldn't stick to it....

cool, that would indicate it's aluminum, right? i guess canister would be the better word than cartridge for this thing....

I like what the guy on greasebenz.com did. Took a cooling oil filter assembly from a vw and ran the heater lines in and ran fuel lines into where the oil should go. Then installed an oil filter in the first one to get the large particles out and then installed a fuel filter on the second one he made to get the fine particulates out

If I still wanted to use a steel tank, is there any way I could coat it or do anything to try and prevent polymerization?

Yes. Well, it means it's not steel. I doubt they used some weird nickel or tungsten metal, so very probably aluminum.
