• I am not in front of my truck with a caliper and tools to remove lines to measure stuff, what size fuel lines to I need to order to change everything?  I'd like to get in my order tonight so I can get it out of the way.

• I does believe they are 7mm between filter and pump, and 3mm between injectors??

• I was staring really hard at mine, it looks like the pump to filter I have used 1/4" SAE line, held up a 5.5MM allen wrench to a pump with no line, and it was really close.  It looked as if a 6MM hose would fit perfect?  They don't sell us Metric fuel line in CA, have to order it
