and i did buyed ( fast 42lbs ) injectors part # 304208

if i did some work in this fuel rail would ill be able to fit the injectors???

 

You can probable use those injectors with your stock fuel rails, but you will have to space up the rails 5/8" (15mm) and use longer bolts. You will also have to change the pig tails in the injector plugs as they are probable different too.

 

You will need to get the installation kit for GM Trucks Nelson Performance sells them and is also a sponsor on the forum.

why didn't you buy the marine injectors that plug right in?

 

Can you post a picture of your stock injectors? You may have the flex fuel injectors and they do make very big direct replacements for them.

 

Cuz he's in another country, he bought what the local speed shop had. Ever try to buy/ship stuff internationally, it's a PITA,

 

oh, gotcha.

 

hahahaha guys will its easier for u in u.s cuz u usually can get all the stuff u need in days


but for me i will wait 2 - 3 weeks and yeah sometimes while ur sitting waiting for ur order and counting hours and minutes when u got ur delivery they sent u wrong item like before i did order an stroker kit for my ford when i checked it it was ford focus stroker kit !!!!!
