What zeb said. I have dealt with a few of them, mostly on idi trucks. I remember one off hand that was in the shop 4 times in 3 months with a plugged injection pump. After the 4th time, his wife okayed me to return the truck to stock, so he could only run diesel.
Those p umps have a **** ton more leeway in them than a new hpfp, so I wouldnt even try it. It says b20 max on the door for a reason...
