i gave a 92 DA its a pain to get to the fuel pump. i bought the car with a turbo setup that wasnt tuned, the previous owner said that the car had an aftermarket intank pump. i really dont want to take his word for it. in case it did have the stock pump. if i add a 255inline will it support 420whp

 

Pick up a Bosch 044 inline Thats my recomendation but a walbro 255HP inline will also work just the bosch is a better pump.

And put the inline pump between the fuel filter and the fuel rail under the hood.
