Fuel Pump Not Pumping...



Hello Nathan,

I'm wondering why you are replacing the fuel pump. Your problem may not have 
been the fuel pump.

The first thing that you need to do is find out if the pump is getting fuel 
supplied to it. I have a few feet of clear vinyl 5/16 and 3/8 hose that I 
use in cases like this. It is avail in Home Depot.

Put a piece in-line,between the line that attaches to the pump...and the 
pump. The clear line lets you SEE what is going on...and if there are an 
excessive amount of air-bubbles traveling with the fuel. If the pump is 
getting supplied with fuel,then....

Attach a few feet of the clear line to the output nipple of the pump...and 
the other end of the line into a clear 2-liter plastic Coke bottle. Dump a 
little fuel into the carb and fire her up. Note the condition and volume of 
fuel being supplied from the pump into the bottle. The bottle should be 
placed under or beside the car and not tediously placed under the hood. If 
spurts of fuel are being supplied to the bottle,your prob lies with 
something after the pump. (Filter,float,collapsed/plugged line)

Is this "New" pump brand-new and never used? If the pump was used at all 
then uninstalled and then let sit long enough for the gas to 
varnish-up,there is a chance that the check-ball is stuck because of the 
residual fuel turning to varnish inside the pump.  <--this happened to me 
with a pump that I had sitting in my parts-shed. I couldn't figure WHY THE 
HECK it wouldn't pump once I installed it. I finally took it back off 
because it would not pump even tho it was getting fuel supplied to it. I 
held it in my hand...said a few foul words to it,then a *POP!* came from 
inside the pump. I reinstalled it...and it has been working fine ever since. 
Weird things like that only happen to me,I guess.

...and like Phil said,there is no adjustment. There are 2 kinds of pumps 
that I know of. The High-Perf pump has 3/8 lines. The pump lever's are the 
same. There is no "roller".

I installed a new fuel pump on my 62 4 door (413). I made sure the pushrod
is above the pump arm but it does not pump. I removed it and checked the
pump, it does pump when moved manually, and the push rod does move in & out
depending on the crank location. It seems the rod is too short, or the arm
is bend down too far. It looks the same as the old one. Is there anything
other than just the push rod? Could something have fallen out? I just have a
steel dowel like pushrod. Is there a roller for the end or something? Any
ideas? Do I need to adjust the pump arm? How?

Thanks

Nathan
