602.962 Biodiesel o-ring and seals

I’m going to restart this post because it answers some of my questions about prepping a 602.962 for biodiesel use.

For now I’m replacing my 1993 vintage fuel line with new regular type fuel line. Hopefully this will last a few years with b20 and the occasional B100.

Quote:
The supply line has a threaded fitting that goes into the tank screen. Unscrew the fitting and remove the hose from the car. There is a regular hose barb under the crimp on the end of the hose. If you cut the crimp off you can put a regular hose on with a hose clamp.
This is good to know and makes it much easier to change to Viton.

What about the fuel heater? Are there any seals that need to be changed in it?

The IP shutoff lever has an o-ring on the shaft. Is the Fryerpower “shut off valve o-ring” what I need?

Can the clear fuel lines after the final filter stay or should they be upgraded?

So it I am thinking that the tubing and seals that need upgrading on the 602.962 are:

1)Under hood black fuel lines
2)Braided injector return lines
3)IP shut off lever shaft o-ring
4)Fuel heater under hood seals ??????
5)Clear fuel lines ??????
6)Black line between fuel tank and hard line

If anyone can answer my questions I’d appreciate it.
