I was recomended to get the GCA758-2
" 255lph High Output 85-92 GM"


But I always see the GSS430 ( something liek that ) recomended on here. Whats the differance ? Is this one going to work ? It was called a pump for forced induction

this is a walbro pump aswell as the other mentioned .


Anyone ? I just don't want to find out the hard way I have the wrong one ...or a lesser desirable one .

That part number is the Walbro 255 lph high pressure unit. It flows the most out of the 255 lph pumps. In other words, you have a good fuel pump. It will flow more fuel than the regular one when used with an FMU. It will flow a little bit more all over in general.

Go to :http://www.autoperformanceengineering.com/
and click on the technical page for specs. Click on the kit page and you will see it is the GSS340 unit.

am I reading it right ...and this is just another partnumber for the GSS340 ? it compars all the specs to " 190 lph ..... 255 lph ... 255 HO lph" but it never gives the part numbers for which .


Just trying to find out what the differances between mine and the GSS430 is ...
----------
K , I am not sure if I read it right but it seems... that the GSS340 is discontinued ...adn mine looks to be the new part number???/
