1BAD2K Posted November 24, 2014 Report Share Posted November 24, 2014 (edited) My factory flex fuel pump is supplying plenty of fuel to my ls6 and mp112. If you wanted something factory and super quiet.... Edited November 24, 2014 by 1BAD2K (see edit history) Quote Link to comment Share on other sites More sharing options...
GI.SS Posted November 24, 2014 Report Share Posted November 24, 2014 Be done with it. Walboro 450 Quote Link to comment Share on other sites More sharing options...
T-Bag Posted November 24, 2014 Report Share Posted November 24, 2014 (edited) The Walbro 255 is what most people use with the MP112 setup on a returnless style fuel system. Shop around Ebay and online or call Brian at The SuperCharger Connection 818-518-9889, tell him Aaron sent you and he will give you a good price and ship it right out :-D Edited November 25, 2014 by NoMoreBadAssSilvy (see edit history) Quote Link to comment Share on other sites More sharing options...

With my mods I still run between 55-65 psi from cruising to hot rodding with no dip in pressure yet... One thing to consider if you are going to run a 2.8 or 2.75" pulley on a mp112 is you need something to counter the high IAT's... You will actually loose performance going from 3 to a 2.8" due to high IAT's and your PCM pulling timing... I remember hitting 185-205 IAT's when I went to a 2.8" on a 80-85' day in Minnesota so I couldn't imagine somewhere down south with higher temps... I installed a Meth kit to help with octane as well as bring down my IAT's... Since installing I haven't seen anything above 170' IAT's and a much, much, slower climb in IAT's... The octane alone is worth it in the 50/50 meth mix as it will allow a few more degree's of timing which translate to a few more HP per degree...
