My 7.3 idi has a mechanical lift pump to supply the db2. My obs powerstroke has a mechanical pump too. (for now)

I put a holley red fuel pump on my 7.3idi a few years ago and after a year I was having trouble starting it. Come to find out the cheap pump was sucking air when it was off all the screws that held it together were loose and the rubber was mush.
