I know that the information is out there, I swear that I have stumbled across it before, but i was not interested in how to at that point.

I cannot find anything in my searches, could sombody please either give me a link? or let me know here how to recognise it?

FYI, I "need" to know this since i have been informed that the O2 sensor socket (that i have yet to get) is dependent on weather it is a return/returnless system. Thanks!
 
return system as 2 fuel lines going under the TB and UIM while a returnless only has 1

Thanks for the fast reply :eek:

now, just to make sure, TB=Throttle Body and UIM=Upper intake manifold? (google thinks it is Un-Insured Motorist, but i swear I'm with progressive I'll ask them how many fuel lines they have:shrug:?)

correct, TB is Throttle Body and UIM is Upper Intake Manifold.
 
Sweet, thanks again!
