    6.7 + Biodiesel + MiniMaxx = Failed Fuel Regulators

    Hi guys,
    New to the site and looking for an answer to a problem. I have a 6.7 and run my own biodiesel (BioPro190) 6700 gallons and counting. This is my 8th Superduty. I have run B100 in all of the 7.3's and my last 6.0 with a minor modification most of which had tuners or chips. I was so sure the new 6.7 powerstroke would be able to handle Biodiesel with a tuner as my last vehicles did. I ran various amounts of biodiesel starting with B20 then slowly tried B40 and even B65 with no problems. Then, after about 15K miles I installed the H&S MiniMaxx Tuner, full race exhaust and a AEM intake. That's when the problem started. The truck ran GREAT but would randomly die when coming down to idle. I researched the problem and replaced the fuel pressure regulator. It fixed the problem..........for about a week. Then it started again. I called H&S they said it was the biodiesel. So I changed the regulator again and stopped using biodiesel. I bought this truck because I love Powerstrokes and was confident it would be the perfect biodiesel truck. It's turning into the worst and I have biodiesel running out of my ears. Any help ??????? Anybody running Biodiesel and any tuner???? Let me hear it.

    G'day JSlayer,
    Welcome to the forum.
    It appears you have an MGTC.
    I had an MGTD in the 70's. I had to sell it when I moved to Australia. They are beautiful cars, I wish I still had it.
    There seem to be more MGTF's in Australia, but very few.. I think they ruined it by putting the headlights in the fender on the TF .
    Amazingly, I saw a TD just this weekend, probably the first one I have seen in 10 years or more.
