Hey man, thanks for all the info...
Couple of things. I replaced the block with a 22R but kept the 20R head (that's why I said hybrid 22R). I know that some of the 20R's had electric fuel pumps but I know for a fact that mine has a mechanical (hole in front passanger side of head) which is why it is interfering with my thermostat housing. I'm pretty sure that there is a pump in the tank as well as the one on the head since I know fuel pumps push the fuel better than pulling it and I don't think that fuel pump on the head would be able to suck fuel all the way from back in the tank... Anyhow, if I go with an electric pump I think 5-9 psi would be too high for the weber I've got (I think they recommend like 2.5-3psi). I have heard carter makes really good fuel pumps... I will definitely look into one of those if electric is the route I end up going. If I DO have a pump in the tank, is it going to cause problems going electric? I'd like to have this truck running one of these days. Any other advice is, as always, greatly appreciated. Thanks!
