Hey troops - my fuel relay decided it didn't want to work anymore and gave up when I was parked in the drop off zone in the airport! Its all pretty blackened inside so I'm guessing its had it - I just had to be trailered back by the AA

So I need to find an alternative quick for the MOT tommorow - I know I can just bridge it, but thats not the safest route to go down.
A new one is £30 from the dealer - does anyone know where I can find an alternative, ie. what cars might have it, or what year?
I have a spare 272 kicking about - but I'm not sure if its the same as the 62, but its in Manchester right now, so I can't compare the two.
Heeeeeelp meeeeeeeee
