Can someone tell me the lenth size and tread patten of the alan key bolts that hold the manafold on the end of the injector pump? One of mine has come loose and has come out. Could i get one that is threaded all the way and can i use one that has a normal head on it?

I dont want to take another out as it is driveable at the moment however it dose leak a bit of fuel out. and i need to drive to the bolt place to get one.

Cheers
