I'm wondering what would be a good size fuel pump to run in my mustang.It's a 90 gt with the following mods.302 bored .030 over forged piston f303 cam ported e7 heads 1.6 rockers edelbrock performer intake bbk shorty headers offroad h-pipe with flows underdrive pulleys electric fan and 100-150 nx wet kit.The throttle body is still stock so are the injectors the mass air is from a 95 but I plan on upgrading this stuff soon.Probably run 70 mm throttle body and something like 73 or 76 mm mass air want to go with some bigger injectors also.I've ran a 110 for awhile I swapped it out for a 155 but it went out so I put another 155 in it and it also quit running,so currently I,m running the stock pump.Somebody told me I need like 255 lph but I kinda thought that would be overkill.I do have other upgrades planned someday like aluminum heads but that will be in the future.I appreciate any help.

Sounds like you have a nice NA setup with a moderate nitrous spray. 255lph is probably overkill, but it's better to have a pump that: 1) isn't straining to keep up with the necessary pressure, and 2) can handle future upgrades.

There's also a 190lph Walbro that would work fine is money is tight.

i wouldn't put less than 255, unless you're using a separate pump system for the wet kit.
nitrous + lean AFR = $$$$$$$$$

255, no reason not to, not even price

considering the price difference between a 190lph pump and a 255 is sometimes $10 depending on where you shop, id go with the 255. leaves you room to grow and even if you dont ever need a pump that big, you arent hurting anything having an oversized pump

I agree there is no such thing as over kill with fuel. a 255lph pump is cheap, and will always give you room to grow later, no reason to not use one.

Hell, my car is pretty much stock and I have a 255lph pump....
