New metal 550 pump cover

Hello all, finally I received the new metal pump cover from the seller, I noticed when I try to fit inside the tank opening it wiggles around rather than to fit tightly like the original plastic one. I know not many of you replaced this but Is this what you guys felt or experienced during installation. I appreciate any input.

Ian, The metal cover diameter is about 1-2 mm smaller than original plastic cover, that's way it is wiggle in place. Got noting to do with the gasket.

 

FBB, I purchased it from superformance.

 

I have not tried with new gasket yet, with old gasket it wiggles. I just did test installation without the gasket compare to original face cover,
The old cover is a very thigh fit, with or without gasket.

 

The gaskets sits FLAT on the edge of the opening, I have the screwdriver tip on the edge. The pump face sits on the top of it FLAT and then O ring goes on.
The face cover should be thigh with no movement,
The next picture shows the position of gasket and face cover, with metal and plastic cover.
My feeling is this recipe for leak

 

Thank you all

 

FBB, I have more work to do including replacing cam seals , I decided to wash the fuel tank with weak acid and water mixture to clean stuck rubber parts to the bottom of tank.
Also waiting for one of fuel pump filters to arrive ( it was glued and stuck to the bottom of plastic fuel can when I attempted to remove made a big hole at the bottom). Looking for good source of chemically resistance wires for pump too. Regarding metal pump covers I may order another pair to see if fits more appropriately, I will keep you posted.
I will need lots of moral help from you guys when I get to the bottom of this but hopefully it will be done the way I wanted,

 

FBB, Thank you, it would be great honer and unimaginable help that I can receive specially when I start pulling cams out. I will let you know.
Thanks, Sark

 

Before I start assembly of the fuel pump, decided to check the pumps if they are are okay. I started to measuring of the OHM value of each pump one is reading 5.5 and the other 10.5 . I checked number of times and the readings are same. What the OHM reading should be on a new one. What this mean ?, it means the one with lower reading is worn off. My electrical knowledge is very limited,
Thanks, Sark

 

I value your comments regarding testing the pump, so I should not consider doing that, what about running the pump in a pool of fuel to flush internal system to check for any residues of rubber debris?

 

I just tested them and both worked. I will proceed with installation of the pump units and the tank. I will post some pictures.

 

Fuel tank project continues, finally I decided to go ahead with original pump cover which is about $1000 less than the metal ones even though they have slight wiggling like the metal ones but much less. I also decided using Fabio's fuel pump holder instead of using black rubber support. All parts arrived and assembly started. I usually get time to fix things on weekends if I can, anyhow. All parts removed and inspected. The black rubber pump holder was deteriorated and was all over, the thank cleaned carefully an power flushed with hot water. Picture #1
The fuel pump electrical parts including the wiring, connections and harnesses all replaced by new ones, took more than a week to obtain the correct parts. I had good luck with digi-key since they are very knollewgable and like to help with the right product, also I am submitting a part number for the products if DIY users like me consider doing themselves without wasting time. Picture #2
Fuel pump corrugated flex hoses received from Quantum in Oxnard California sizes 9 mm x 220 mm with 2 clamps for new pump cover instead of using gates submersible rubber hoses. Also replaced the anti vibration by Amazon products recommended by Ferraridriver ( Dave ).
I could not do this without the help I received from my wife, thank filled with couple Fallon to check the leak from drain plug an temp gauge. Finally with some struggle tank repositioned in original place. Picture #3.
The new filter attachment hopefully would be easy and I consider instead of replacing the whole left fuel delivery rigid pipe ( even though I purchased a new pipe ) just replace a piece by a connection to the fuel filter by DORMAN products, will see.
