fuel filter change

[jesse]

switching to bio diesel looking for advice on how to change fuel filter. should I wait a few tanks or switch it out right away.

bio huh... what percent are you going to be running? make sure you do some reading, bio breaks down rubber. your hoses, seals, gaskets in your injection pump are rubber. even bc transit when they converted to bio, Note the word ( converted) had switched all their busses over to synthetic seals and lines. yes you can run on bio for a long time with no issues, but you will end up with some issues, or just replace all your rubber with synthetic
just my $0.02

Does that include the B5 that Columbia Fuels is selling?

I understood that everything under B20 was 'safe' enough to not require an overhaul of the fuel system.

well Im not going to say use it or dont, a while back , Im not sure what post or thread its in, but I put some pump Bio fuel in some a couple jars with some rubber O rings and some slices of fuel line and over a few months there was some minor break down, the fuel line and the o rings started to "sluf" how ever this has to be said that the small test I did was not kept in the dark to simulate the inside of a tank or pump and did not have any Flowing over it. simply sat on a shelf and looked at every few weeks to watch the process.
I would think that b5 should be safe to use as its being offered to the public, all I can say is that if transit went to all the trouble of converting over to synthetic to use the b5, well thats enough for me.

Well changing your fuel lines is a good idea what ever fuel you run, with ULSD/LSD (ultra low sulfur diesel) here combined with fact that you have 15 year old fuel lines... (I think something like 95 or newer is better/fine??)

It's not the lower sulfur that affects your fuel lines, it's the fact they change the blend of hydrocarbons in dino-diesel to create similar properties. Too boot LSD is; less stable, possibly more bacterial growth, can contain more water and can cause filters to plug up quicker. Also too boot; biodiesel is certain to have trace amounts of meth (methonal) in it which is a powerful solvent the nice old hose and gasket materials.

WVO does softens the lines too.... but I just can't think of how to explain it with another drug reference; LSD, meth, and mmmmm the ecstasy of running on WVO.

I'll stop now.

Okay, so after all of that, what is the remedy, considering most diesel vendors are going to start selling ULSD or LSD starting this year?

What is the part list for replacement? What does that part list cost?

[EnviroImports.com]

well every diesel retailer sells Ultra Lsd, as the sulfer was the lubricant, there is not Part you need to put in your delica, you need to start using a fuel Lubricant. most of us sell it.as its a must or you will find out what injection pumps cost to re-build. and while your at it, start using biocide to kill the bacteria that grows in diesel fuel , and no there is no way to stop that growing either.

Wouldn't upgrading your fuel lines and related gaskets with the newer style (synthetic) help as well?

[EnviroImports.com]

Help yes, but a synthetic hose or gasket wont lubricat your injection pump, and if it does, its breaking down lol , this is also Bacteria season, Water ie..condinsation in lining your fuel tank mixed with pump diesel grows bacteria, and lines your fuel system ENTIRE fuel system with a film similar to the effect black mold has on us humans, it WILL take out your whole system.
