Keola,
The GSS 340 is what we use. Pull the red cap off the base and put on the filter I provided you with. The GSS 340 and 342 are the same pumps except that the 340 has a larger inlet and uses its own filter. We do not use the 342 because you have to reuse your stock filter and the inlet is very small.
yep, useless on a NA P5....unless you've got a 240whp NA engine...
