    The Bakelite mounting block that sits between the fuel pump and crankcase on my 1800 has a crack in it and it therefore leaking oil. The pump is stuffed and obsolete. I can not seem to find a new block anywhere but was thinking of removing the pump rod and just mounting the pump hard up against the case to stop the leak. Anybody see any problems with this solution? Or better still, anybody know where I can get a block?

    Only problem is the pump itself as there seems to be in all my working pumps an open connection through it to the drain that has the little pipe that vents into the tin ware. if your pump is totally stuffed I would stick some high grade silicone into it and then bolt it back up as you suggest, or make a blanking plate. Either should fix the issue.

    It's been non operational since I've had the bus and doesn't seem to leak from the pump itself. So there's no problem with removing the shaft and leaving it out? Does it just pull out on the type 4 motors?

    You can buy (or make) block off plates for fuel pumps

    The block is to stop heat disippitating into the pump and bringing on fuel vapour lock..so you need a material that will not transmit the heat.
