fuel injector sizeing.

[Hemet8]

I have a 1995 3100sfi. The fuel injectors i think are 17/lbs per hr. Can anybody verify? When finally get around to do the heads and cam, i would like to run 19lbs and keep the stock fuel press reg. Will this work? What are the fuel injector ratings for the 97-99 mini-vans(3400)? And what are the injectors for post '99 3100/3400's? Will they just "plug-in?" Thanks for any help with this.

RE: fuel injector sizeing.

IIRC, 97-99 injectors will not just plug into your existing harness. I'm pretty sure you can modify the harness to make it work though. Keep in mind that larger injectors will do you no good unless you modify the PCM to take advantage of them.

99 was 18#. I'd be happy to sell 'em to ya. Was B&B by marren fuel injection, then ran for about 1 year. Removed for 42.5#

Happy to take pics and even scan in the flow sheet from marren...

I got 98 3100 injectors and fpr. The 18 #'s. I hope they will work well with my stock 3400. Seeing as how the 2.8 and 3.1 used the same injectors. The V6's run rich stock dont they? So it will be a bit leaner than stock, but hopefully not too lean.

Are you saying the '97 to '99 injectors will not plug into his '95 harness? That's not the case if that is what you're saying. The injector connectors were the same from '87 (at least) to '99.

I am wrong then. I must have been thinking of the '00+.

Here are some images of the '99 18# injectors...

Thanks for your help, Todds '99 18lb injectors have the exact same set-up as mine. So as long as i stay at '99 or before, i'm good.
