I have a 99 civic si. I am running hondata s100 with boost. I am using an inline fuel pump and need a walbro or some other type of in tank pump. I heard walbro makes two different types of 255 pumps for civics. A high pressure and a normal pressure. Which one should I get??

 

high pressure

 

I heard I don't want the high pressure. Is the high pressure 110/hr

 

the guy from lightning motorsports told me that's exactly what i needed.

 

GSS342 high psi can be bought anywhere for $85~$100.

 

The only time I would think you wouldn't need high pressure(GSS342) is if you were running a Fuel Pressure Riser (FMU).
