fuel pump question

I'm going to be upgrading to 24lb injectors I'm planning to use a walbro 155lph fuel pump, is 155lph enough or do I have to go bigger thanks

isnt the stock like 190lph... i have a holley 255lph and it has helped alot and only about 20$ more than OE.. i would see the MAF sensor giving you more probs than fuel pump with those new injectors.

stock was 88lph in a fox.....155 would be sufficient but why not 255 for future upgrades

the only reason i was thinking 155lph is because i can get one for about 55 bucks, by going with anything over stock I'm assuming i will need a fuel pressure regulator right
