i just started installing my fuel pump upgrade from mazsport my only problem is that i don't know where to run the vac line from the fuel pressure regulator to.....i guess i connect the silcone tube to the copper line then the other piece of silcone tubing to the other end of the copper line then to a vac. source somewhere but it didn't come with instructions and mazsport i s closed until the 12th this month and i don't know where to connect it or if that is the right way any help will be appreicated.......thanks

 

Turbo application??

If not..it probably doesn't matter...the regulator is set to increase fuel pressure under boost....

Otherwise where you have your manifold fitting for your boost controller should work

 

Where in SWVA are you?

Are you turbo'd, why the upgrade?

Good Luck, I'm sure someone will chime in.

 

call mazsport! they are more than willing to help

 

i know why he upgraded---stock system is not that sound and to go lean under boost is a death warrant. Now if he is not turbo'ed --then dont know? If you track a lot the fuel pump unit ends up being a maintainence item.

Yes, Im am turboed and live in big stone gap, VA. The reason I upgraded is that I went to bigger injectors and the Interceptor-X EMS so I needed more fuel pressure...I have the fuel pump installed now thanks for the replies it help to confirm the way I thought it should be connect....I couldn't call mazsport for help they are closed til the 12th and I was right in the middle of the install and need help asap thanks again everyone!!!

 

keep an eye out man--not only is pressure important but volume is also. Seems like you are doing all you can do. Good luck.
