I picked up a spare TPI system awhile back, and it has a Adjustable FPR, but the weird thing is... It has no Vacum fitting for a Vac hose to hook up to it. It this normal? This isn't a home made jobby either, Will this cause any problems?? Or am I ok. Cause now that I installed it the car runs like a bag, it is set at 50psi. And it appears the injector on cylinder #2 is not working now, as the car is missing badly, and the header tube is not getting very hot, checked sprak it's there, so it has to be a fuel problem. Any suggestions or ideas??

Thanks,

Kaz, that's really not normal. Without a vac reference the injectors are getting max PSI all the time. I've heard of stock injectors failing when pushed past 50 psi, like mine did Maybe you could TIG a vac spout on there? If you can wait a few weeks you can have the AFPR i'm taking off my GTA. It's not perfect but it's cheap. Is this the TPI setup on the SS?

 

Thanks Paul. Yeah this is on my SS. DANG!!! So that is why the one injector stopped working. Well I have a few weeks or more to wait now anyway so that I can afford new injectors. What do you need for the AFPR your taking off the GTA? I am going to need it. Thanks alot Paul!!! I appreciate it.
