Hello, When filled completely the fuel is leaking from where you fill it up. (maserati khamsin), After removing the inner trim I found the cause of that, 2 tubes are not connected. Does anyone know how they must be connected? Or to wich tube? (see picture) Thanks Image Unavailable, Please Login
Every Khamsin I have looked at is different in the fuel and vent system! There are a couple of things that the top tank connects to. A vent via a carbon canister, from memory of my car its mounted above the tank and forward higher up, and the other I think is a fuel return from the engine manifold. The aft one in the picture may be the return to the tank from the canister, the other one appears to be a check valve. I am guessing but it may be as simple as putting a hose between the two. The carbon canister on mine had three connectors one was.. a vent.. the other two one connected to the tank. the other blank. I actually dont think it did much except keep the authorities happy! Sorry I cannot give you a definitive answer except some idea of where to start. Regards Graeme
Graeme, your car had a carbon canister? I thought at the time that was still a North American market exclusive. I haven't taken my rear upholstery out yet, I don't believe though that I have one of these, and if I do it certainly isn't connected anywhere on the front end of the car, so what is the point? Authorities, yes, just like with the smog-pump on cars with Euro-headers and no thermal reactors. Also my car 120.435 does not have a fuel return. It would help if the OP would give a few more details, I suspect a NA market car, in which case I can't be of any help. Best, Jack.
Oh that does look rather dangerous. Why would anyone be so stupid (not the OP)? Are there any fuel system diagrams available for the Khamsin? Even a USA diagram might provide some sort of a clue.
I don't know the answer, but it seems that what you have is not the original hook up. A reasonable guess is that the two open connections were joined together. Try removing some more interior trim and feeling around in the compartment for the hose that fell off or rotted away. Attached are copies of some photos from the manual available from Maserati Net. (You should get yourself a copy if you don't already have one). Hopefully this will help you sort it out.

Hi Jack The Aussie compliance cars from 1976 on,were fitted with carbon canister as part of the Australian Design Rules.ADR 27A ( now a Federal Government Act) and AIR-pump with some fitted with Euro-headers and no Cats. Mine had a fuel return from the engine and to the top tank and one from the canister. As I said no two cars were the same. Graeme
I have another manual which is much better. That little tube is a vent no hoses are connected to it Hang on just got to figure out how to scan this Cheers Mark
Here you can see the car completely. If you look at the 3rd attachement, the tube on left wich is not fitted is the tube coming from the top of the fuel tank, this makes no sense. Maybe there just needs to be a little fuel filter on this tube and it must be hanging on top as a vent hose, but then i don't understand why tha other tube is coming out of the reservoir. In the owners manual with the car the drawings aren't the same. On the left side (not in these pictures), there is what I think must be such a fuel canister, but i don't know where that one is connected. Maybe i must remove everything then it's much cleare.

My guess is, that there is a carbon canister in there, that got saturated blocking the vapor-path, and it was disconnected to cure pressurizing of the tank. In that case, hooking it back up will cause a problem, unless you also replace the carbon canister. In any case, the situation as it is now is rather dangerous. Best, Jack.
This all distressingly similar to my Espada's fool system. All that fuel and the associated plumbing essentially open to the interior of the car with only some fiberglass, foam rubber and pricey leather as a barrier. Bertone quality. I agree with the carbon canister theory. Best to identify where that outlet goes, appears to be a splash resistant vent?
Hello Timmerklits, I can get you help from the top expert technicians but I would need the chassis number. I do not recognize this car which seems to have a Belgian number plate. If you can provide me with the chassis number here or privately if you prefer at [email protected] I will be happy to help you. The chassis number begins with AM120. Since you have long/low exhaust tail pipes (as is the case when not yet raised after a Euro bumper conversion) it would seem to be a US car converted to Euro bumpers and sidelights so perhaps it is AM120US1044? Best regards, Marc Sonnery Maserati Khamsin Registry
