Subject: [GMCnet] TBI Questions & Google Groups

Greetings all, I have some questions that perhaps you have answers to. I would direct these to the Google Howell group but it is not accepting new
members or is without an administrator. The context is I am installing a new to me Howell TBI system with embedded locker on my 455. BTW, I swapped
out the Holley TB for a GM from a 454 Chevy.
Question 1: I've tried to obtain access to both of the Howell-related Google Group sites dedicated to the Howell systems. I've received no response to
several requests for access rights. Is there no "owner" or "administrator" taking care of them right now? Suggestions?
Question 2: Has anyone used Applied GMC's small surge tank with a FI system? Did you plumb the bleeder valve output with a "tee" to your TB's fuel
return line? Did you add a check valve?
Question 3: I have one of Tom Pryor's MB Diesel electronic clutch fan setups sold by Applied. Has anyone used the fan output of the ECM to control a
relay powering the MB fan clutch? Any issues?
Question 4: What are folks experiences in the ability of the built-in GM fuel regulator to deal with the higher pressure output of the TBI's fuel
pump, example an Airtex 2182? Anyone modify their TBI to make the fuel regulator adjustable or add an external one?
Question 5: Anyone change from a one-wire NB O2 sensor to a three-wire WB O2 sensor? It appears to me I'd just need ot add switched 12v power and
ground. Will the ECM accept the WB without re programing?
Many thanks, Jess
