well, the 1st year TBI came out was in the 87 Square Body up through 95, FYI.
I have an '80 Suburban (factory carbed), the '80 sending unit is longer than the '95 sender. 87-91 suburbans I wouldn't know what their senders look like. Never owned a TBI squarebody. Point is, I made that 95 sender work in my '80, meaning the '80 31 gallon Suburban gas tank. That alone is irrelevant to what I asked.
Apologies if I offended. I understand 'working with wat u got' if that's the only option. I just think it's unrealistic to believe it's going to work reasonably well.
Well hate to break it to you, as i will state for a 3rd time now, it ALREADY has worked for me. You are late to the party on that one, but appearantly you missed that. Wasnt my original question. And your feeling of it being unrealistic is also not relevant to the conversation as I was already successful in what specifically stated, with a different project from 3 years ago
Correct me if I mis-read anything.
So the reason you want to delete the return line is because the return fitting is broken off the sending unit?
The TBI has a built in regulator, it is designed to operate with a regulator, and the pump may have a short life if it is run with a regulator that has no bypass.
You already modified the sending unit/tank or both in order to mate them up, why not just add a new return fitting to replace the broken one?
If the sending unit is placed in the tank properly, the pump produces appropriate fuel supply, and the return line provides adequate bypass, I see no reason why the system couldn't be made to work as well as factory.
Originally, when I started this thread. I asked simply if I could run a 13 psi pump with no return line. Has nothing to do with the broken return port on the sender as I found another one from a guy parting his truck out. That idea has since been abandoned all together. I converted the L19 to CARB and it runs ****** great. Have an inline pump that is controlled by the illuminated toggle switch.
