I heard after you put a walbro fuel pump in you need to get rid of the J tube because if you dont your car will run really rich. I was wondering if I have an safc with the lexus afm and 550cc injector combo if I can tune the safc so I can keep the J tube. Is this possible?

Thanks,
Brady

why not just bypass it or drill out the hole.... nothing major to do... i believe it's the fuel pressure that's the problem.. kinda takes a toll on the stock fpr

How hard is it to get to it?

The J-tube isn't hard to get to at all. It's near the front of the motor, under the intake manifold. Bypassing it wouldn't be hard at all, and, unless you have a blank plate, leave the J-tube plate on. That is, unless you want to see your crank.
