The turbo is alive again! I think bypassing the gizmo did the trick, the difference in power is absolutely amazing. I can hear the turbo whistle and the truck accelerates much faster. Thanks for your help David!

I ended up plugging the extra vacuum hose, looked a bit but am not quite sure where it goes.

It is amazing how much crud a couple gallons of biodiesel has solved out from the tank and lines. I have owned the truck for a little under a month now and am on my third primary fuel filter!

Yes, the bosch pump has lots of potential for fuel flow, just be careful you don't blow the head gasket like we did <img src="/forums/images/graemlins/scared.gif" alt="" />.


Will an upgraded intake and exhaust prevent a blown head gasket from increased fuel consumption by allowing the engine to breath more?

Also, a sign of a non-working turbo is-LOTS of black smoke. (provided someone hasn't turned up the pump!)

I have an 86 diesel out of a Ranger in my D50. It was a real dog before I took after the pump with a screwdriver. Now it blows a ton of smoke, outa the exhaust and off the tires!


What are the adjustments you made to the ip to increase fuel flow and that oh so desirable black smoke off the tires? Also, what other measures did you take so you didn't blow up your engine?

Is there a proper order to take as far as what upgrades to make first so that everything works together without a complete blow up?
