Does the entire pump have to come out? Or can just the housing be removed? Working on it tomorow. Engine serial 0F153718. 5.7 bravo 1. Fuel pump NOT mounted on water pump.
On mine it is only the 4 bolts for the pulley and the 3 nuts for the pump to come out. They have to be removed to do the job anyway so just remove it and do the work on the bench.
Depending on the room you have to work around the pump area, you could either remove the whole pump assembly and take it to a bench or you could unbolt the pump housing from the base and slide the plastic housing off the shaft.
Most likely your pump housing will look like the first photo below while the original would have looked like the second one below. If you decide to leave the bracket in place, you'll have to be able to gain access to the nuts (item # 23) that go to some of the bolts in the first photo. It's really all about finding the most comfortable way of gaining access to help determine what process you should take. Good luck.
The 3 nuts (#23 from the above pic) are the only thing that hold the pump to the bracket. Those have to be removed to separate the housing. One those are removed the onlything keeping in the bracket is the pulley. My boat it smaller than yours and can't imagine doing it with it still in the boat.
If you have the older style like the second picture above you can use the single piece housing with no issues.
With the help of my 20 y.o. son who is much smaller than me, after a couple of hours, 2 red bulls, and a lot of bad words, we finally got the pump out.
impeller replacement from this point was super easy. Although somehow we managed to swap 2 of the bolt locations and changed out a long bolt for a short one which created an interference and couldn't replace the pump in the mount. Took it back out, swapped bolts, all good.
For anyone who questions how necessary impeller replacement is, I submit the following:
Hope your able to find all the missing pieces. Those little pieces can clog up your power steering cooler, thermostat, and restrict water going to the engine. Fist place to look if you don't have it all is the PS cooler.
It looks like you removed it the hard way. If you take the pulley off then the 3 nuts on that go on the pump housing bolts you don't have remove any of the mounting hardware brackets.
