Filling T350 with petrol

[Whizz65]

Have had TVR's for a number of years and there're not the easiest of cars to fill with petrol.
However the T350 (which I’ve had a couple of weeks and love) sprayed petrol out when I opened the ball valve this morning, it’s a pig to fill but I can live with that.
It was a hot day and I opened the petrol valve very slowly and it started to spray out, obviously I shut it and put a paper towel over it but quite a bit of petrol came out. The gauge was showing 12 litres.
Anyone else ……….. someone must have the same problem? Any suggestions?
Many thanks

I've had mine modified to a sagaris filler. Can go full flow now with zero spray

TVR made it that way on purpose.
Its so other people at the petrol station have more time to drool and admire your car.

Was this design ever changed during the T350 production run?

I've never had spray when opening it and assuming I don't put the petrol nozzle right down then I don't get any splash back when filling - I did notice there is venting holes when I peer into the filler hole..

I have always had the same problem. I soon learned that by opening the valve slowly it minimises the risk. However it doesn't eliminate it.

Spray used to be caused when you filled to the top and closed the ball valve holding a little petrol in the valve, when you then opened it hot the escaping pressurised air would blow the valve petrol out.

I think they did attempt to drill a hole in the valve so that it would drain into the tank but I think that was towards the end!

I have a 2006 model and as long as I don't push the nozzle too far and don't try for an F1 refill time (yes I know they don't do it anymore) it's fine.

Dito.. though mine's an 2003 model, but I suspect it may have been upgraded

Another reason could be a blocked roll-over valve, carbon canister or the associated tubing. The valve sits behind the passenger side b-pillar cover.
Vaporized fuel due to heat from exhaust increases pressure inside the tank and can no longer vent. It then does it violently when you open the valve. I agree that spitting fuel requires it to be in the ball valve recess itself as with 12l in the tank I dont think it would spit.
Blockage would also make filling up even more time consuming

Sorry, but how is it modified, is it an easy mod?

Could the fuel carbon canister or pipe work be blocked, making the problem worse.

The Sagaris fuel cap is one of these: http://www.newton-equipment.com/aero-filler-cap-ra... so I guess bodywork would need to be changed.

Some body modification is required to make it fit so you will need to have a qtr end respray. S&D also modified the pipe routing when they fitted it.
I get zero spitting, blowback, hissing etc now when filling and can also go full flow right to the pump cut out which is a major blessing.
AFAIK mine is one of only 3 T350s to have this mod.
