like the title says i got a 95 camaro with a lt4 swaped. my question is what kind of fuel set up should i go with stock is 3.0gpm(24lb) injectors and not sure on the lph on the pump.

Mods: k&n intake , shorty bbk headers , stock Y pipe dumped , lt4 hot cam

should i go with a stock replacement or like a walbro xxx lph keep in mind i'm going to be spraying this with 50 to 100 wet on a window switch

My friend with a 95 lt1 firebird formula is running a 125 shot with long tube headers, exhaust, and CAI on stock 24lb injectors. I thought lt4 came with 28lb injectors. If you have 28lbers i wouldn't wory about it. If not upgrade to 30lbers, just don't forget to tune it after. I would go with an aftermarket 255lph fuel pump to.

thats true i put the spec down for the lt1 the lt4 specs are 3.5gpm and 28lph. but my main question was should i go with a 255 or stock which flows less then that with the mods done to the car and the future on spraying, thanks for the advice

Upgrade to the 255lph. My friend on the stock cam with 125 shot upgraded to the 255lph but left the stock 24lb injectors. Since you have a cam too i would upgrade the fuel injectors to 30lber if you have 24lbers. If you have the lt4 28lbers i wouldn't worry about it.
