The fuel pump story starts with removing the old one, which of course isn't exciting in the least. However, once removed it exposed something else that gave me pause- amidst the thick, dark sludge that remained in that section of the block there were coiled pieces of metal. They appeared to be the remnants of a spring from days gone by, possibly from the original fuel pump. I knew that it had been replaced due to the presence of Fel Pro blue gaskets.
These pieces in conjunction with the undiagnosed noise from earlier combined to make me quite uneasy. This purchase was starting to seem like it might have been a mistake, but I powered on.
I proceeded to take my old fuel pump with me to the Auto Zone store, as history had taught me it would be necessary. I'm glad I did because when I placed it on the counter and announced what vehicle I was working on the guy asked me what part I needed. This of course was after he looked up from his phone screen, which was now sitting on the countertop still playing videos at full volume. He never left his seated position on the stool.
We looked and looked throughout the system and just couldn't find a 2 port SBC fuel pump at this store, but there was one 7 miles away. Trying to find the giant oil filter I sought was even more difficult so I thanked them and left, and since I still needed a fuel filter I decided to just buy everything at the other store. Presence of mind dictated that I stop at the O'Reilly's that was across the street from store #1, possibly saving me the hassle of driving to another town. This visit was fun because nothing listed for Oldsmobile was correct and we combed through parts for K5 Blazers, C10s, Corvettes, El Camino's, etc. ad nauseum until we found one... For the 1978 El Camino I suggested from the start.
Then we searched for a fuel filter after I described what it looked like to the young man helping me. This resulted in me simply typing "Rochester fuel filter" on Google and showing him a Fram part number to reference for a Wix unit. Now that I had a fuel pump and filter I needed that oil filter.... but couldn't stomach the $24 Wix price tag at this juncture. I refuse to use Fram for anything, and I don't know enough about Micro Guard filters to trust them so I returned to Auto Zone (store #1) for a good old S5 from STP. Unless they've changed in the last 10 years I've always known them to be a blue Wix oil filter.
Once I returned home it was of course raining again, so I just accepted that and went to work. This is where I hit another snag that I should have caught earlier: My new fuel pump came with 2 gaskets for the pump and none for the plate that goes between it and the block. Fantastic.
I was pretty sure I had one floating around the garage (again, for 20 years) and after searching a few places like this one
I managed to find it over by my bench grinder. Here's the trio.
I found myself to be completely without any type of gasket maker or sealer of any kind, so I had to be extremely careful to not tear this bad boy during installation. It's a good thing I put the pump gasket on upside down and had to perform half the procedure twice- I needed the practice. Utilizing the bolt designed to hold the pump pushrod out of the way I was able to finagle the setup into place and tighten the bolts. I reinstalled the factory fuel line between the pump and carb and crossed my fingers.
