Filled up on B20 prior to taking off on a 1000m trip.

On the return trip, running normal ULSD, I kept getting repeated P0148/P0087 (fuel delivery error & low rail pressure). Even with the edge clearing on start-up, the codes would pop up with in 20 miles after clearing.

I turned the mp8 & edge all the way down & drove her on home..

Just ordered a fuel filter... I read somewhere that BIO loosens up deposits created by dino-diesel & its a good idea to change the filter after the first time using it.

You guys think this should fix my problem or do I need to dig deeper?

PS.. the current filter has about 12k miles on it... time to change anyway

On our boats low fuel pressure means look for leaks, change filter, then replace fuel pump. In that order. That is not the same situation, but I'd look for the same. if you have no leaks then change the filter. If that doesn't work look at your fuel pump. Maybe things are different in trucks.

Ordered the fuel filter from diesel manor, along with the pillar mount for my edge..

The code hasnt come up today, with the edge/mp8 turned all the way down... it sure is boring to drive though!! :peelout

Thanks for the help fellas, i wanted to make sure I wasn't just throwing parts at it unnecessarily
