Pre-Filter or Secondary filter - your experiences
Posted: Fri, 26 Jun 2015 11:33 +0000
OK. I know this topic has been done to death but......
I've been reading through all the posts about this and there seems to still be some dispute about whether to use a 30 micron prefilter or a 2-5 micron secondary filter.
As I understand it the 2-5 micron secondary filter will do a better job of filtering and is better matched to the injectors hole size but MAY result in premature pump failure and fuel pressure warning lights etc.
Obviously the 30 micron prefilter is to remove the larger particles and can separate water, but wont to anything to stop smaller particles.
Some filter Kit manufactures promote secondary kids for our D4Ds and other recommend filter kits. E.g. Diesel Care promotes a Secondary Filter Kit while western Filters recommend a Prefilter kit (Fuel Manager).
Given a mate of mine just paid put for a full engine rebuild after DIRT (not water) found its way through the OE 10 micron filter I'm leaning towards a secondary filter but am worried about the pump failure/pressure issues.
Who here was either setup and what have your experience?
