How to remove 3200 Fuel Pump?

[RichTaps]

I've gained access to the fuel tank in the boot, but have no idea how to remove the gold fuel pump locking rings! The Maserati Workshop manual simply shows a picture of a 4 legged removal tool of some kind, but absolutely no further info as far as I can see.

I tried to hammer the locking ring anticlockwise using an allen key in one of the circular holes, but I don't think this provides enough shove.

Any ideas?!

You could make your own tool from a piece of plastic drainage pipe with the correct diameter ( six inches or so should be enough). Cut the lugs out of one end and drill a couple of holes in the other so that you can put a bar through for leverage. It works on the SAAB fuel pumps but haven't needed to try it yet on the 3200.

It’s a faff but I imagine it will take the making of a tool. Some suitably sized bolts through a bar would do it I suspect.

If it’s the same as the 4200 (I suspect it is) blunt large flat blade and a hammer and tap it round.

Thanks all. It does seem to be significantly different to the 4200 from what I can see.... The 4200 pump def looks more conventional and easy to remove.

Anyone else done this job that can offer an opinion? I’m kind of assuming I don’t need to make a tool as this must have been done many times?!

@madmanmart may be able to help.

Zep’s suggestion or buy a pin wrench.

Has anyone tried to buy the correct tool? Just asking lol.

Making a tool is the best way, two pins that can fit into the holes on the lock ring and a length of bar.

I’d at least consider it if I could find any trace of it actually existing!!!

i suspect that's how I got my two out. I do not remember building or buying a special tool, and i got them out easy enough.

After a bit of research it appears at least part of the fuel system is shared with the Ferrari 456, which seems to use the same locking rings (also same as the f40 apparently!) . here is the tool from hill engineering which I think will work. I’ll give them a ring to confirm dimensions. Bit pricey but good to know.

Thank you - Great to see an example of how to make such a tool. I’ll get out the welder and probs take this route. Saves a few quid

The more I take apart the 3200 it is really interesting to see quite how many Ferrari parts have been used. As well as Fiat and Alfa of course

Exactly what was in my head.

This is excellent home engineering.
The hill tool looks like plain studs to interface with the pump flange. Are the holes in fuel pump threaded ?
