Ok , I haven't pressure tested my fuel pump yet , but talking to people , they say it sounds like its on its way out.I priced out fuel pumps today , almost 400 with my discount <img src="/forums/images/graemlins/scared.gif" alt="" /> Now , my question is , will a fuel pump from a 2.6 MPFI work on a 2.8 TBI? Its almost the same pump looks wise , but I think the MPFI is higher PSI at between 35-45 , and not sure what the other one pumps out.I figure with the extra pressure it would just mean more fuel pumping through the charcoal cannister and going back through the return line.
Any thoughts or suggestions on this?
