In-car filter recommendation for wvo? - PeachParts Mercedes-Benz Forum

Full Monte · #1 01-25-2007, 08:49 AM

I looked through the wvo links for an answer to this but didn't find it.

I see a number of different filters for wvo being used on Mercedes diesels, and am trying to decide what's the best option. I kind of like the Goldenrod filters because of visibility, but am not sure the housing would stand the 160-180 degrees F temperatures. I also plan to use an electric pump to move the wvo. I've also seen VW filters, Frybrid, and any number of can-type filters on machined bases. Any suggestions from you experienced guys would be appreciated.

Here's a thread on a fuel / water seperator.

FM100 pre-filter upgrade: easy install, adds water seperation, inexpensive...

If you look at post #47 you'll see what I did. It was inexpensive and a good fit.

Thanks for that. Nice install. Has anyone used the see-thru Goldenrod filter cannisters in this application (not just the water seperator)?

vormax filter has a clear glass cup to see whats going on in the filter and whats being trapped. It is also coolent heated, i hooked one up to my friends 300SD and it works great so far.

I've had very good luck with my greasecar filter system but if you have more money to spend the other options with real coolant heat exchangers and clear housings look nice.

I tried the FM100 with a WVO (prefiltered to <5 micron) and it clogged the filter before I made the block. I use a goldenrod (same as firemediceric) to handle the water filtering in the garage (you should carry a spare for in car use). The housing is all metal and would handle the moderate temp you are discussing. This model works well with WVO. Can't help you with the clear ones, but they can be installed with a heater. Have you tried asking the company about temp ranges? Why an electric pump?

I think the Goldenrod water block spin on is rated to 10 microns, so it is more than a mere seperator. The amber models can be obtained in different ratings.

I've had a plastic housing goldenrod on My '59 ford for 15 years, in the engine compartment, and a 292 V8 and Fordomatic produce a lot of waste heat. I won't say it is totally safe, there is always a chance of an accident and an engine fire, but I personally have never hit anything witht he front of the car. In my 240D I have the goldenrod mounted right front against the front bulkhead, hung by the metal tubing adapters off an angleiron bolted to shocktower bolts. It is on the passenger side above the airconditioner reserve tank. That is a pretty cool location. Goldenrod also sells a spin on metal filter, which I don't like because you can't see the water and drain it out without dumping a lot of fuel into a pan. I drain on the road sometimes, not all my trips are local, and 3" of water in 500 miles is pretty typical for bought fuel in the winter. With plastic you can stop when the separation line gets to the bottom, no fuel drained. I got used to draining glass/plastic filters with the OEM on my '59 ford, and now with diesel it is more critical than ever, especially in freezing weather. Adding power aide additive doen't seem to emulsify the water, I'm going to quit buying it.

Davco 234 seems to be one of the best ones out there right now: http://www.davcotec.com/fp234.htm

I'm still designing the fuel system, but was planning to use an electric pump on the wvo side so that I could leave the MBZ diesel fuel system "unmessed around with".

I have been changing my views on WVO vehicle filters over the years. Proper pre-filtering and dewatering makes a HUGE difference in how long the onboard filter lasts. For my latest conversion, I use a second stock filter for WVO and now have well over 10,000 miles on the element.

I agree with the last post.
Think ahead & avoid full tanks of WVO / biodiesel going into cold weather. If you want to wake up a attentive service station (do these exist anymore) attendant, start filling by putting 2 gallons of RUG in the tank & toping off with diesel!
One solution is the diesel heaters. Do a search on this site. Greasy_Beast drove from the E. coast to Montana using 2 gallons diesel in such a heater, heating his WVO system. Added benefit is warm startups with warm cab. Pricey, but these units are built for semi trucks & with proper care, should out live you.
