Hi everyone,
I'm in the process of converting a 5.7 SBC for a marine application. The long block that I purchased did not have a fuel pump, so I ordered a new one which looks like photo #1.
For comparison, the fuel pump on the old, 5.0 Mercruiser is in photo #2. You'll notice that I added two red arrows showing where the housing bolts to the block.
The issue that I'm facing is that style mechanical fuel pump doesn't seem to fit on the block that I purchased (1986-cast, non-Vortec head). Please see photo #3 for where the fuel pump is supposed to attach to the block. As you can see, there is only 1 bolt hole.
What am I missing here? Do I need to install an electric pump? If so, can I install it inline? As there is no room in the tank for sending unit and also a pump.
Any input is much appreciated.
