DES is an Akai authorized service center (or were when I was last there). They can do anything to the fuel injection system and have everyhting. Just carry it all down there and install it when they are done. They have done great work for me.

I make my own biodiesel and run B100 and have no problem with fuel delivery and don't beleive a pressure build is in this system's best interest anyway. They could advise yu better of course, and I would listen to every word they say.

Good luck,
