When I bought my car it came with a Stock in tank pump and an aftermarket boost a pump.
I bought a Walbro 307 with a shimmed pressure spring (should pump almost as much as a 340, pulls more current though).
Now what I want to do is put the 307 in and leave the booster...Will this make my 307 pump more then a 340 or about the same??
