evildky Posted May 29, 2004 Share Posted May 29, 2004 ok I have been having fuel cut out issues with L28ET, so I added a fuel sump to the oe tank, ran 8 an hard lines to the filter and pump (msd #2225) and 6 an hard lines up to the engine with a pressure gauge and a bit of rubber line before entering the fuel rail, the problem is that I am now running 60 psi with my fpr turned all the way down !? should I upsize the return line? reduce the feed line to the pump to a 6an? everything is the same save for the sump and supply lines and I can't get the pressure any lower !? and it seems to be too rich at the bottom to the point that it's a bit sluggish off the line, ideas?

TimZ Posted June 11, 2004 Share Posted June 11, 2004 Are you sure that the regulator is working? Seems like that MSD pump shouldn't be able to overwhelm the stock return line by that much. If you are sure that the regulator is working, then the proper solution would be to upsize the return - choking off the supply kind of defeats the purpose of upgrading the fuel system.
