Charles are there any adverse effects of installing the walbro early. I dd this car and am slowly doing my project install. If i were to put the walbro in before it was needed for FI and do the following ,mods would my ecu freak out and would I be able to fix that with my utec.

Very helpful info.
I modified my fuel assembly pump for my APS kit. I now am installing the CJM S1 & need to know if the 12mm hole I made is too large. It says .0430" in your instructions.

Damn...
Just by looking at the pieces I knew the answer, it's been a long time since the APS install.
Sure U don't mean .430" ?

Is it absolutely necessary to drill it out like that? Would it make my car run safer? Will this method have issues like the turbonetics way of doing it would?
edit: nevermind I just read the rest of the first post.
