Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Fuel leak

Thank you all very much for the many (and much appreciated) answers!
I’ll investigate a bit further on the filler/hose side and provide some feedback on dealing with the leak.

Cheers,

I had a longtime fuel smelling problem during this summer. The reason was a buckled petrol hose between the petrol tank and the roll over valve. The underlying cause was a broken bracket of the roll over valve. Subsequently the pressure in the petrol tank is encreased. Now I‘ve fixed the roll over valve and renewed the petrol hose.

Would anyone know the best way to examine a recent 4 seater's fuel tank (what to remove first aside from spare wheel etc.)?

Cheers,
Vladimir

Dear All,
Few years after several attempts to cure the problem (ie epoxy sealant, full hose checks, filler cap seal replacement etc), that terrible fragrance had me decide to replace the whole thing: Mulfab is prepping my tank for shipment next week I believe Neale knows what he's talking about. He asked me for several photos to best match the tank. The piece will be stainless steel, hopefully not too heavy compared to the original aluminium tank
Any recent experience on fuel tank replacements?

The fuel tank on my 4/4 Sport also split at high level on the weld joint, which was also caused by pressure problems combined with a weak weld joint on the tank.

Once my tank was replaced by the dealer (under warranty) this caused further pressure issues which resulted in me being sprayed with fuel when I released the filler cap, it was worse when the tank was low on fuel. Some TM’s say a rush of air is normal, however the factory say it is NOT. Slight air release maybe yes, is ok. So my advice is to check that you haven’t also got a similar problem?

The problem was a kink in the line somewhere on my car, and the roll over valve being replaced and repositioned.

This is quite a rare problem (so I’m told) And more problematic on Sport models due to no spare wheel, as the side screen storage tray sometimes obstructs the fuel tank pipes etc.

I’m no mechanic, It’s info received from dealer and factory.

I designed those SS tanks when I worked for Mulfab

I have them on the shelf ready to ship....

Thank you very much for sharing!
And for the pictures.
I will have to check the pressure as well, most definitely.
Cheers

Sorry SimonH but I’m already in business with Neale
They must be really good if you participated in their design!
Cheers,

I don't believe it's a rare problem. I had it on my 2005 roadster and my 2014 4/4.
