What are the injector sizes on the fuel rails and intake 14mm or 11mm? Talking about the o ring diameters for the rails.

88 tii intake and rails

 

all T2s came with 550 cc injectors. they are 14 mm. the problem is some were low impedance and the rest were high impedance. for the most part, it breaks down to S4 (low) vs. S5 (high). however, according to what i've read over the years, your 1988 can be either, depending on when it was made. i guess the easiest way to tell is to look for a resistor pack.

I don't have a 2nd gen. Doing a fresh build in a fb. And I'm to picking injectors and final steps for a build. But thank you for the info! Just seen both options 11 vs 14mm for them.

 

okay, gotcha. i thought you were saying that you had an '88 T2.

so at the risk of telling you something you already know, here's a video to show how to get the impedance/resistance of the injectors you have.

if you don't have any Gen 2 reference material, then you can get a copy of the FSM from: Foxed.ca
