Biodiesel pre-filter at fuel tank

[ImSoAmish]

Has anyone added a pre-filter between the tank and fuel conditioning module to handle the biodiesel filtration? I have a 2006 and have started testing small ratios of blended fuel. Anyone using the Golden Rod or have opinions on using it as the pre-filter?

I use a NAPA water block on my storage tank. Once the BD goes into the onboard tank I rely on the stock .5 micron filter mounted on the rail for any additional filtering.
I run B100 most of the year, blending down to B50 when the temps fall into the 20's and straight dino when the temps drop into the teens.

It's not a bad idea, given the chances of when, not if, of getting contaminated or dirty fuel.

Here's a couple ideas:

TDS vendor, ITP Diesel pre-pump fuel filter kit for the 7.3: ITP 7.3L Fuel Tank / Pre-Pump Kit This is a good kit. I've helped a 7.3 owner install it and it's pretty easy, the hardest part is lowering the tank (true for both kits). I have no idea if Dennis (ITP owner) will sell the kit without the 7.3-unique parts.

A careful look at both will show a common design feature: the use of biodiesel compatible fuel hose. If you want to run bio-compatible hose, do NOT use SAE J30R7 standard fuel line hose (cost = $1/ft.) Use SAE J30R9 Fuel Injection Hose (cost = $4/ft.).

You'll also note that both kits replace the entire fuel line from the tank to the pump. This is good since it eliminates the vacuum-leaky quick disconnects that Ford uses - which are great for pressure but leak air under vacuum, which is bad news for diesel fuel system.



Note that both the Baldwin and the Wix/Napa fuel filters are only rated to about B20. If you want to run B100 all the time, then you'll have to go to places like JMEsales.com and find a B100 bio-compatible filter that will fit the ITP kit or the Wix fuel filter head 1"-14 threads (which is a standard fuel filter thread).

Good luck.

Wow. That covers my question very well. Thanks. BTW I am making my fuel and is why I am concerned about extra filtration. I am still fine tuning my quality and quality testing methods.
