i searched earlier but couldn't find anything about them for stock port 12a coexi don't know much about the topic. so what should i get and what is it gonna do for me?

 

you only need an aftermarket fuel pump and regulator if you are swapping you stock carb and intake setup with an aftermarket unit or each. installing a high pressure fuel pump without the regulator on a stcok carb will flood the engine. and its pointless to feed the engine with a high volume pump and regulate it down to stock pressures. you've just wasted your money. if you install an aftermarket carb and intake, you will also need to install a better complete exhaust such as a racing beat exhaust.

 

that's cool. the cars got a rb intake and exhaust and im hoping to get a sterling carb.

 

Racing Beat recommends the Carter fuel pump & regulator.

 

You can outrun the stock pump pretty easily with bolt-ons, especially if it's old. With a Sterling or Weber, an aftermarket pump is pretty much a necessity even though the stock pump's output pressure is technically okay for those carbs.

 

a gsl se pump will provide enough pressure and with a regulator you should be good, the pump wont run you much here in the forum

 

I'm not sure that you could use a FI pump (GSL-SE) and then regulate it all the way down to 4psi. I see blown pumps in your future if you try that, but I could be wrong.

Here's my writeup on the pump/regulator installation: https://www.rx7club.com//showthread.php?t=529605

Good luck with your upgrades.

so an fi pump would pump to much to regulate it and it would break the pump?
i do know that when i used it, it broke my cheap purolator regulator, thats why i took it of, but i thought itv was the regulator that sucked not the pump having to much pressure. that makes sense
