Ok quick question. My fuel pump is discentergrading as we speak. Now i was looking around and found that i should upgrade my fuel pump to a 190lph = 50gph = 301 lbs of fuel = 600 hp. Now the problem is that well a 85-95 ford mustang 5.0 l efi fit in an 89 tbird 3.8l? Would i have to change my fuel injectors or keep the stock. And will this give me more horses or not. Yea one last thing what does this mean 190lph = 50gph = 301 lbs of fuel = 600 hp? I found this fuel pump off of jegs the brand name is called holley in-tank electris fuel pump. Is this a good brand?
