Finally got my hands in fuel pumps in my 04 Spyder. The right side pump is under the metal cover and sure enough there is a leak and those 4 "pies" on top of the pump are filled with gas, as described earlier in this thread by jscriscuolo. I wonder if his glue has held all the way to this day. I will send a PM as well to check.
The pump is only a couple hundred bucks...

I know, not very expensive, a bit over 300 is cheapest that I have found. Left side is even cheaper, around 150. But I am qurious to know how that epoxy has been holding. I fixed my MGB tank 25 years ago, hole in the bottom of the metal tank, with aluminium mesh and regular epoxy. Has not been giving any trouble since. Did also another tank years back, and same results.

That's metal...this is plastic...

True, gluing plastic is not very reliable solution in the long run.
Pumps are made by Bosch and the left pump has the fuel gauge. Looks like the right pump is identical, just without the gauge, and right pump is more expensive and not that widely available. I bet that left pump would fit on the right, by simply just removing the float and wiring.

If I am not mistaken, YouTuber Samcrac mentioned this while he was fixing his Ferrari 360. Look that up. I seem to remember that he was talking about how to use left pump for the right one or vice versa.

I have both the ones I just pulled and replaced a couple of weeks ago. Will look at the float.

Importantly, these are both Ferrari parts...which does change the math (and availability) for the better.

I am not 100% sure whether this is applicable. So please do your homework.
This video confirm exactly what I was thinking about these pumps being the same. My findings so far tell me that the one WITH the float is cheaper, around 200 usd, so looks like I am going to order that one, strip the float and I will have a spare float for the next project.

Makes sense. Please make sure to come back to this thread with your lesson learned and part numbers!

Received my new pump in number of days, ordered from UK website and product was shipped directly from Latvia by TNT, so it was fast. Total cost around $150.

I was going to change it right away, but noticed that the epoxy I had used to stop the leak has somehow miraculously cured the leak. When I applied it and tested the following day after applying it, fuel was still leaking. After sitting for about a week, not using the car it was just fine, no leak at all! Very strange, but that is still the situation after several days. Planning to put in the new pump but kind of qurious to see if that epoxy just keep holding for another few days. Obviously, it will give you a termporary fix, just be patient before using your car, at least few days. 24 hours was not enough.

My new pump is Bosch 0 580 313 104, and that level sensor was very easy to remove. Ready to go in and now I have a spare sensor.
