Pull the filter and the line up front. Put a hose over the end the filter came off of and blow some air through it. Then blow some air through the end that goes to the pump. Now put a new filter in and test it again. You are testing it with a jumper on the fuel pump power lead so that it is running when your testing correct? Also it could be a bad regulator that is opening too soon as well.

tbi uses a low pressure pump, tpi uses a high pressure pump, tpi will not even attempt to run with a low pressure pump, the diff is about 40 psi between the pumps.
