Well I picked up one of these puppies up from MAP along with a fuel pressure gauge kit from Ultimate Racing during their xmas sale.
Installed the gauge first and tested on my current pump, DW300 and I was running pump gas:
43-44psi. I was shocked! Unmodified fuel system other than the DW300 and FIC1680's.
Converted back to e85 and pressure dropped at idle to ~40-41psi:
So I decided to forgo punching out the siphon right away and just throw in the new pump and see what I did. I was pretty shocked:
~44psi on the nose.
I'm running a boost-a-pump, and with the 1680's and DW301 pump I've been about at the limit of the fuel system since I converted to e85 in May/June. This pump very obviously flows more up top, time for most boost and more mods I guess?
