Please Help! 99 F350 Fuel Problem

[overdalimit]

I need some help. I have a 99 F350. I purchased the truck a few years ago and when I bought it (Ohio) and was driving it home (Louisiana) it broke down in Tennessee. I barely made it to the Ford dealer. Upon diagnosis the tech found out that it was a fuel pump problem. We found out after inspection that it has a SX Performance fuel pump (model#18203 w/41002 filter) and aftermarket regulator. The entire factory fuel system has been disabled and the new fuel system installed complete with lines and -10 AN connections. Now, I am having the same problem with the pump. After I replace the fuel pump fuel it blows shortly afterwards but while running the regulator gauge fluctuates which indicates irregular fuel flow.
Now, when I look up the pump on the SX web site it states that the pump is not to be used for "Low Sulphur Diesel" applications, due to lubrication issues and that the warranty is voided if used for diesel. Now, for the question.....Can someone please tell me which pump will stand up to low sulphur diesel and live. I need a pump with -10AN connections. Which pump are you guys using. I purchased the truck with a 100HP predator chip installed, so that must be the reason the previous owner upgraded the fuel system.

Please, I need to purchase a pump that won't leave me stranded! I don't have any faith in the SX pump. It looks good but........

Couple of choices.. You could go with a FASS stand alone 7.3 pump. An Aeromotive A1000, or use a stock 7.3 12 v pump with adapters to get onto -10an..

I'm using an A1000..
