I want to go to a Walbro 255lph High Pressure pump,I have found for kits go up to 1997. Model # GSS340 is the pump to use, is it also direct fit for 98 ?I think I have returnstyle-car build date 08/1997 and model year 1998. This is photo from my car. Is it difficult to change fuel pump basket to make it work with Walbro GSS340?
