I have seen multiple 42# injectors for sale for our trucks but i was wondering if the most commonly used injector is the 8.1L 42#ers? Would the 8.1L injectors be a direct replacement for my stock 6.0 injectors? Where is the cheapest place to buy the injectors? If the best place to get them is at the dealership what is the part number? Thanks alot

 

Here's everything you need to know. http://cgi.ebay.com/ebaymotors/ws/eB...147410999&rd=1

 

they're on ebay all the time . . . 110-130 . . stock 8.1 truck injectors - PN# 25343789

Then there's the Marine #42s 17113739

both are a direct swap and drop

 

thanks but it doesn't answer all my questions i just wanna make sure that i won't have to splice any wires or use a spacer

 

They are a direct swap.

 

thanks man that's what i needed to know... what is the # on the stock 8.1 truck injectors 31#?

 

OEM# 25323974, AC Delco# 17124531 (superceded by 12574927)

 

What happens if you just drop them in? Will the truck run rich ?

 

yes they need to be tuned for

 

advantage over 8.1 or marines?
