Have replaced fuel pump and fuel filter but cannot get gas into the carb.

Here's a pic of the pump where I have labeled what I believe to be the correct vent, inlet, and outlet. I'm tracing hoses and making sure none are clogged.



I'm really lost here and cannot figure out why I can't pump gas into my carb. I've been able to suck gas into the gas line where it enters the engine compartment but I can't suck gas into the fuel pump (maybe designed that way). Any ideas?

 

Ok, I've gotten gas in the lines up to the inlet to the fuel pump (given the above picture is correct which I'm 99% sure it is). I have no clue why the pump is not pumping gas then. Is it worth it to pull the pump off the cylinder head and pump it by hand to try and pump gas?

 

Disconect the fuel line from the carb and crank the engine over a few times, if fuel comes out of the hose then the pump is good and the float in the carb is probably stuck. if you get no fuel out of the pump with the hose disconected then the fuel pump is bad.

 

You're not gonna believe what I think the problem is... Uploading picture of the head.

 

I pulled the head off and I can't see how what is on the camshaft will drive that mechanical fuel pump. I had to use lots of force to force it to pump and the part of the cam shaft that touches it is almost prefectly round. Did they forget something that drives the mechanical fuel pump?!?

 

Well, when I buttoned up the head I didn't know to move the elliptical lobe thing that sits behind the cam sprocket... I did wonder about what was there to drive the fuel pump but I also wondered about a 1000 other things per day during this engine replacement...

It took me all of 20 minutes to pull the head, put the truck in gear, pull off the cam sprocket, install the lobe thing that drive the fuel pump, reinstall distributor with the rotor in the same location, put the valve cover back on, and connect the distributor up.

End result is the truck now runs!

final picture of what I was missing....

 

the ecentric lobe!!! doh...

 

where was the eccentric lobe at before you moved it to there? Do you have to take off the head and move it everytime you change the fuel pump? I'm confused b/c i'm changing mine as well and when I put it on I didn't feel any resistance on the inside of the engine.

 

do not have to take off the head to do the fuel pump, my guess is he either rebuilt the motor, or put a new head and timing chain on and forgot to put the lobe back on when he put the timing chain on. It almost looks like in those pictures it's got the efi spacer in there instead of the carbed fuel eccentric.
You may or may not feel resistance based on where at in the cycle the lobe is in. the lobe is a circle that is off center like a cam lobe. if your at the base when you remove the fuel pump there is hardly any resistance from the fuel pump rod on the lobe. Just make sure you only use one of the white plastic spacers between the fuel pump and the head and both supplied gaskets. The old plastic spacers like to skick on the head when removing the fuel pump. you have to remove that and the gasket that will be between the spacer and the head.

 

My van is a 1984 ford e 150. I've put 2 fuel pumps on in a row and original pump seems ok.ckecked lines and tank and can
Not get fuel to pump.is it possible that the eccentic has broke or simply too much sludge in old motor with bad blow by problem?
