I have been running commercially made Bio Diesel B99.9 (beef tallow based) for about 6 months in my 99.5 F350 with 7.3

I have just experiances what most say is the pick up foot failing in the tank-they are saying that the Bio mad have accellerated the deterioration of the foot which looks to be plastic:

My guage stopped at 1/4 mark and I ran out of fuel.

Lots of folks are saying to do the common "Hutch" mod to the tank/pick up, I am concerned that some say the inline filter that is supplied with the kit from Strictly Diesel is too fine and can cause pre-mature failure of the pump.

This is the kithttp://www.strictlydiesel.com/p-2662-driven-diesel-fuel-tank-pre-pump-kit.aspx:

Any advice? Thanks!

 

Really just trying to see if anyone else has experianced any type of fuel system failure due to using commercially made B99.0 fuel.......
I have been using it in a VERY clean to start with fuel system for 6 months now and my 7.3 really likes it-it is Beef-Tallow based......

I can't speak to the use of commercial bio, but I've been making and using biodiesel for almost ten years, and have never had any fuel problems with any engine I've used it in.

 

Good to hear!! Thanks!

 

DO the 'hutch mod'.

DO NOT use a filter like the one they sell in that 'kit'. In fact, my DIY 'hutch mod' cost less than a couple of Happy Meals including the WIX 33972 pre-pump filter. For $170 plus shipping, their 'kit' better include cocktails, lap dances, a 1hr massage AND a happy ending if they want my money.

Here's a link to a write-up, but again - I don't think the primary-type filter before the pump is a good idea (even Bob ended up adding another fuel pump to compensate for what I think is a poor design here...):

Fwiw, those things fail in trucks that have never seen anything but diesel - you can't really blame this failure on bio-d.

 

I did the Hutch mod, and then my fuel pick-up ended up falling apart so now I am done with the whole "1/4 tank" problem and I am putting in a fuel sump.

(BTW, this will also help with a design flaw in the Greasecar system: In order to use 1 pump for diesel and grease, Greasecar moves the fuel pump from the low point under driver's side door to a high point on top of the engine under the hood, making the pump work harder than it should.)
