Getting close to getting my 76 260z 2+2 on the road, but just having a problem priming the fuel.
When I got the car it had been sitting for a few years, so I drained the tank and filled with fresh. I got the pump primed and all was good, but it was a pain and took a good 20 minutes.
The fuel was quite dirty so I drained again and primed with fresh again, and it was still painful.
The engine ran fine etc.
After a bit more investigation I found that the tank was quite rusty inside, so I removed the tank and fixed using the KBS tank sealer.
Now I have filled it with 40L of fuel and can't get it primed.
This car only has what appears to be the original type electric fuel pump and no mechanical pump. The electric pump has been wired to run whenever the ignition is on.
I have tried the following:
Both fuel lines disconnected from the carbs and placed into a container so I can see the fuel flow.
Fitted new fuel filter just before the pump and confimed that fuel is flowing out of the filter when the line is disconnected, so no blockage from the tank or filter.
Sucked fuel from both fuel lines that connect to the carbs.
Jacked up the rear of the car.
Still not getting any fuel flow from the pump when switched on. I understand that it could be the pump, but it sounds fine and would be unlikely seeing as the car has not been used since it was tested recently.
The thing that concerns me is how can the pump not be primed if I have sucked fuel at the carb ends, or can it be sucked from the return without realizing?
Any ideas would be great.
