I'm installing a fuel cell and going to run an external pump (probably a 190lph walbro?--not a 255 for sure). This is a pretty stock n/a 2.0 engine. Am I going to need to upgrade the regulator? What should I expect the fuel pressure to read(at idle I am currently around 40psi) with the walbro and the stock fpr? I searched, and the topic is covered in a handful of threads sorta, I can't find one dealing with a stock engine. Thank you for any clues.

i searched a little harder(which i shoulda done better, i apologize) and found my answer. thanks anyways guys. this is the best joint on the net!
