I agree that the heated filter helps.

For the '84 I've got a metal shell diesel filter (stock item for '85 VW Golf diesel). All I did was spiral wrap some copper tubing around it and plumb the coolant from the heater hose, back of the head, through the copper tubing, then into the hose that runs back to the WVO tank (with the fuel line inside it). Filter is mounted behind the left headlight in the 300D (where there was plenty of room). Pretty simple and the VW filter has a water drain built in.

I had my injectors cleaned and tested when I got the car at 302,000. We'll see how they look after a summer on WVO!

I am new to the list, so forgive me if I am posting this to the wrong area. I have fairly recently purchased a 1976 300D, and want to convert it to Biodiesel. I was told that the engine was rebuilt in 1990, bu have no proof of that nor do I know what specifically was done. What should I do to convert to bio? I know that I need to change my fuel lines and proubably the shut off pump (oh, yeah, and have a snot load of filters with me at all times). What else do I need to do?

SMac,

If you run BioDieselor a DIesel fuel Bio mix, nothing needs to be changed.

Its running straight vegetable oil that causes problems in cold weather.

I thought that there was a problem with the rubber and some kind of degradation due to entering a carbon nuteral compound into somthing designed for petrodiesel

This system has proven itself for algae problems in regular diesel, so I'm gonna give it a try on my SD. I just converted the system and still running virgin oil. My home storage/filtration setup is coming together. But this seems to be a very important subject that I just found here.

http://www.algae-x.net/prod_catalyst.htm

these products may well revolutionize our whole process. I'm picking mine up to run inline on the SD and also picking up the fuel catalyst to treat my home storage when it's all set up.

I'll keep you posted

I hear from some long time truckers that the new low sulfer diesel does not lubricate the IP system like the old high sulfer diesel fuel Anyone have experince or thoguhts on this? Along the same lines I wonder if the B20 I run has any similar adverse effects in my early 80's 300D, SD & 240D? When I last fueled up at a B20 station, the pump handle splask back guard wqas about dissolved to shreads... I doubt it was rubber. Made me wonder what the polycarbon components of my fuel sytem and engine might be doing with constant B20 biodiesel usage....

2 things.. First, I've run WVO in my powerstroke for an entire summer, without any conversion** and the only thing I can say is that a F-350 with a clogged fuel filter is no fun. (** the PSD has the fuel running through the head which essentially pre heats the fuel to above 150-180)

Secondly, I did not get any black stuff out of the filter when it clogged. The only time I got lots of black crap was when I ran B100. Went through 3 primary filters and a couple of spin ons before the system got clean.

I would definitely check further if you are having starting problems with Bio-D. My car and truck luv B100, quieter, stronger.....It's the way to go !!

I remember reading on there, that a capful of ATF will make up any lost lubricity from ultra low sulphur fuel.
I would suppose that if you use Diesel Fuel Catalyst from Redline, and follow the graduated marks on the side of the bottle, you can get quite a few tankfuls of lubricated fuel per bottle, if you don't feel comfy with adding ATF.

All Bosch FI pumps use the engineoil to lubricate the pump, not diesel fuel. Also, ATF in your fuel will actually cause your injectors to carbon up. There are several MB bulletins that speak to that.

So, like, what lubricates the barrels where the fuel actually is?

I don't think that a capful (not cupful / 8oz) of ATF is even going to be noticed by the injectors.

This would seem to imply that sulphur is a lubricant, is it? It would also seem to imply that oil company engineers are idiots, do you think so? Even if they were, don't you think that engine company engineers would have a word with them?

Tbone,

I thought it was a well known fact tha sulphur in Diesel fuel was a lubricant for the injection pump.

Supposedly there is an addirive on low sulphur Diesel fuel that makes up for the lack of lubricity.

Palangi and Pequod,

Engine oil only lubricates thelower part of the IP: cam, cam followers and bearings. The barrels and plungers are lubricated by the fuel.

P E H

Exactly my point

Well, sorta. The sulphur is not the lubricant in the fuel, but the process used to remove the sulphur also decreases the lubricity of the fuel, requiring additional additives to meet the ASTM spec for diesel. The concern is that the ULSD may only meet the minimum requirements. We'll see.
