Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing MulFab and Petrol Tanks

That's probably true. but it is a welded item I am thinking of getting. It does not help me much if the Hard Chrome king pins are really good, but the tanks may have welding that has not fully penetrated.. I will talk to them on Monday.

Just for clarity, has anyone else had an issue with Mulfab's welding? .... it would be a pity if a company's reputation was rubbished on account of a single failed weld being reposted numerous times years down the line ... if it is something that has been ongoing then fair enough .. but if it's an isolated incident then, failing 100% weld x-raying like critical nuclear or aerospace applications, then maybe it belongs in the 'sh*t happens' file?

No connecrion to the company needless to say.

Excellent point.

I don't know whether the rads are made at or for if from an outside source for Mulfab but Simon of Sifab fame used to work for Mulfab and I believe made the rads there. Now, when you see a Sifab rad the welding is superb and the top bracket mount is clearly stronger than the Mulfab option. If they are made in house why haven't they been revised as it seems there have been quite a few failures. Now a failure to a rad is water but a petrol tank is a different matter altogether

So, does anyone know more information on this subject re the welding queries. Sifab also made tanks too!

Simon worked for Peter Mulberry before he retired and way back in the day I spent a couple of hours at the old workshop. I don't recall Simon working for the current Mulfab company or whether he sub contracted to them, All I do know is that Simon has great skills in welding aluminium.

My car got a mulfab radiator for two years now and I can say nothing negative. Very nice contact and fast delivery. And no problems until now. The factory plastic rad is absolut rubbish and I would not go for it.

Simon's bracket weld is definitely stronger and satisfies the engineer in me ... however, the curved weld on the Mulfab one is plenty strong enough (if their welding is usually competent) .... if they were destruction tested I'd put good money on both of them failing through the tank material ripping rather than weld failure.

PS ... if what Sewin says about multiple failures is confirmed then maybe that's the time to consider alternatives .... I commented as this example is the only one I remember seeing on here and it was some time ago .... in the real world there will always be an odd failure .... just concerned that this may have been a case of 'the internet never forgets'

My understanding is that the current (& for some years) Mulfab, bear no relation to Simon or Peter as we knew them, Simon left several years before Peter finally retired and he sold the name and rights to the designs to the current engineering co based at different premises to Peters original workshop

Thanks cooperman , that makes sense to me now! My car is 14 now so am thinking of changing from factory to alloy before the coming failure and I'm starting to feel a little more reassured.

The American market seem to use chinese made options at roughly half the price and seem fully satisfied with them.... They don't make a duratec plus 4 option though! Mulfab say the failures are due to bad installations but I will be fitting it myself so I'll make sure that stress wise I'm satisfied before I call it fitted. It seems its the only available option anyway.

Any more of you with experience telling of your experiences with the current version would be most welcolm!

I'll just add my experience, just for general information purposes.
I bought my roadster MK1 in 2004. It had a central radiator mount via a rubber cotton reel (an exhaust mount ). It regularly ripped the rubber in half as there was so much movement of the rad. I discussed a solid mounting with the dealer so we fitted something tougher whereupon it ripped off the ledge which was "welded" to the rad. I glued it back together with liquid metal glue and fixed fireproof heavy foam down each side of the radiator. This stopped the movement and also improved airflow through the radiator. It never gave me trouble again.
My point is, I suppose, that there is likely a huge amount of movement of the rad when the car is on the road, a severe test of a weld or joint if it's all focussed on one small area.
