I want to bypass my heater core (1963 f100 p/up), most threads say to bypass at the firewall. Is there any pressurization problem if I just run a hose from the engine block connection (the connection that would normally go to the heater core) to the water pump connection (the connection that would normally return from the heater core)?
Hey all - my truck has had a gas smell in the cab, more than what I would expect. Now I am getting some seeping around the wire connection that comes out of the center of the sending unit. It seems worse when I tighten that bolt down. Any suggestions are, as always, appreciated. This forum has been a great help! No seeping at the screw mounts. I tightened all this down about a week ago, along with any accessible hose clamps to try to eliminate the smell. First noticed gas few days ago, did fill tank today.
1963 f100 water pump. I have tried to order a replacement water pump from GMB and although the impeller size matches (4 3/4) and the GMB pump mounts to the engine the nose size and diameter are wrong. I definitely have a 63 292 Y Block V8. I think the GMB pump might be for a car even though it is supposed to be for a truck. Here's a few numbers - the GMB pump that came is 125-3110 and the ford part number I thought might be right after searching the forums is B6C8501B but the impeller on that pump is only 3 and 7/8. Here's a couple of casting numbers from current pump. 575 0796 also P 614 on the pulley. Any insight would be great! I guess is all else fails I could send the current pump out to,be rebuilt.
