I have a 92 TBI 5 speed.. I am going to switch out to carb in the near future.. Just a couple questions.. I will be running the edelbrock performer rpm intake with an edelbrock electric choke 600 CFM carb (1406).. also a vacumn advance distributor from jegs.. I have read the tech article saying to purchace a 3 port regulator to do this swap.. I have come to find these are not cheap.. Why exactly couldnt I just do away with the return line (block it off) and simply put a simple single inlet/outlet regulator in the line before the carb.. I dont belive i would go as cheap as the one at saw at autozone today for like 10 bucks but i would appreciate someone to explain to me the "pro's & con's" of my idea.. Secondly I know the intake and carb will perform better but after a mild cam and a set of heads (maybe l-b9 or l-69) could i acually expect a solid on the street noticable difference in performance?? the car is currently running high, high 9's in the 8th

 

Our fuel pumps were'nt designed to be "dead-headed" like that & will burn out without the return line. TBI guru's correct me if I'm wrong.

 

Moving this to the carb pros.

 

it won't work, as he said they aren't meant to be dead headed, it will burn the pump out quick. the only type of regulator that will work is a return style. personally we have tried others with no success. yes they are kind of expensive, i think the Mallory 4309 is around $80, but it's worth it to have stable and reliable pressure.

here's mine...

 

Yup its either spend the 80 bucks on the correct afpr and be happy or buy the pos cheap no return line one and have to replace the fuel pump shortly after.

 

.... that actually should read: buy the cheapie, then replace the fuel pump and buy the right regulator later.

Sometimes the cheapest way is to actually spend more money up front. Least expensive too.
