I am currently running the racetronix in the tank with a T-Rex F/P in line, I have been told that racetronix does not recomend running there internal pumps with external in line pumps, If so why, and is it hurting the performance.

 

would the racetronix pump alone, even with the BAP installed (boost a pump) satisfy your fuel needs? then why use the external pump also?

different pressure(s)?...idk

 

Thats what I am trying to figure out.

 

Running 2 pumps in series will do little to increase flow, it only serves to help increase line pressure. This is why they are used with FMU's on boosted applications. If you were trying to run 80psi pressure this can help, but at the 40-60psi range, they do very little.

 

Thats the answer I was looking for. Thank you!
