Why, is his actuator on the way out too?
No - but his brakes are squeeking a bit - and has anthracite coloured wheels, and there are a few rattles , etc- but of no consequence- and he is due his annual service soon.....

For anyone interested, Sam at Stradale Italia in Uttoxeter (where I left my 4200 Spyder after breaking down) discovered the right hand fuel pump was broken. It was only delivering half a bar of fuel pressure rather than 4 bars (I think he said). So only 4 cylinders working and a bunch of lights on the dash including a ‘Slow down‘ message. Think was also affecting the alternator/battery charging which has improved since the repair.

These fuel pumps are discontinued, obsolete and are almost impossible to get hold of. Fortunately I think I found the last new Maserati one in the UK (seriously!). the Maser 4200 community needs to work out how to get these in the future.

Glad you are sorted. These in tank assemblies can usually have the pump itself replaced, rather than the whole assembly. Just need to identify the pump.

Interesting. It is only sold as a complete assembly. Sam said it might be possible to disassemble and try and rebuild but not easy.

We have a pair of new 4200 pumps on the shelf if you need them. It’s the rubber that breaks down from the E10 fuel and jams and shorts the pumps.

Thanks - I’ve found/bought the left hand pump already as expecting a problem. But I’m puzzled as Maserati and all the forums/advice says that the 4200s are fine with E10 fuel. And apart from the odd occasion, I always use E5. But interesting- I’ve kept the old one so will examine it and try and work out what happened.

I suppose saying it’s all down to E is a bit dramatic but it’s certainly accelerating it. We are replacing a lot of 80/90’s Ferraris with this issue, Testatossas and 355’s mainly.

The kits can be bought new but what you don’t want to do is expect to just replace the pump motor. When you remove them you will see the issue with the rubber parts

Already done on Maseratilife years ago. For a Spyder it's a Bosch 0580313104. With float. The float can be removed for the other side. Cant remember which way round. Units readily available at various places for as little as £120 a side. Gasket and fixing rings are sold separately.
