Richards Revenge (aka biodiesel ate my HP fuel line)

Joat...30R9? Is that a nitrile inner liner with rubber outter? From my understanding the 30R9 will eventually be degraded by B100. Under pressure the BD will permeate the hose and you will have a greasy mess again. Viton and teflon is all I use.

You're thinking of 30R7. SAE 30R9 is flouroelastomer barrier lined, highly resistant to biodiesel and all other fuels. The outside is not as resistant so spills should be cleaned off.

When you say hose shop, you mean like autozone or oriely right?

Hose shop for a fabricated hose would be more like a hydraulic hose shop. Usually listed under "hose and fittings". They can build you a slick stainless braid over teflon hose using the old one as a pattern.

From the front of the heads to the Fuel Pressure Regulator (on the side of the filter housing), There are 2 of them.

The '99 and later models DO NOT have these lines that are an issue. The mechanical pump OBS's are the ones with the issues.

The SD's have steel tubing feed lines from the filter to the heads, dead end system with no returns lines. The OBS's have mechanical pumps with steel feed lines and rubber return lines.

On a SD only need to upgrade hoses if you've done modifications with rubber hose. Also with higher concentrations it's best to use a heated prepump filter to help prevent waxing in cool climates.
