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.

How does one go about bypassing the j-tube. Do you cut it off or something?

Ok, after you drill out the tube, how do you attach the line to the plate? Do you have to weld it on?

You're drillng out a tube that the return line is already connected to. So once you've finished drilling and cleaning, you re-attach to the same location.
