Need some help guys. Prepping for the intake install and pulled the injectors to clean them. I got new o-rings on the injectors but I'm having a hard time finding part numbers for the o-rings (#4 below) on the fuel rail cross over. Any help will be greatly appreciated.

 

If it's the same as the ones in my 04 LM7, it's one of the sizes that comes in those giant assortments of green ones in the plastic box with dividers. At least that's where I got one when I needed it, especially since I already had the assortment. Plus, I still have at least 8 or 10 of them, and about 200 other ones that fit everything from AC to transmission lines to household appliances to ... everything. Less than $10 for about a half-pound of O-rings, and no more chasing after part #s.

 

Thats probably the route I'll go, I need a good set anyway, but I'm not sure I'd use the green ones for fuel. To my knowledge they are for AC sys and not for use with fuel. Not saying you should run out an change them if you arent having issues though.

 

Not for the last 100 or 120,000 miles or so... maybe after they get broken in though, who knows...

The truck will turn over a quarter of a million miles in a few days.

 

haha!
