Ok, Im an Idiot.

I got my car going, but I now realize that there should be a spacer between the head and the mech fuel pump, something the stupid previous owner forgot to put back. I had one kicking around in the spares he gave me. I put it in a really clever place, so I would remember to put it in before starting the engine again. Well, I forgot where that clever place is, and am now without this spacer. No big deal, I plan on making one using a gasket as a template, shouldnt be that hard. The big question is, how thick?

Also, just for information, what does this spacer do? I have read a few times that its very important to have it. I ran the car without it for about 10mins, and everything seemed fine. Any input would be appreciated.

Thanks,

Adam

I'll measure mine a bit later this evening, if no one else posts before I get to it.

Two reasons I can think of for why it's important. One is that without it the pump lever may be pushed too far which could damage the diaphram. The other is to isolate the pump from the engine temperature to reduce the fuel temp, thereby reducing hte tendency to vapor lock.

Thanks Arne...

I did a bit more searching.. and found itm so I guess I dont have to make one. Mine measured in a 5.5mm.

Thanks,
