Re: [AMC-list] so many issues 71 hornet wagon



Linda, several problems might be at play here. The first culprit (to me) would be the vacuum fuel pump. Possibly the first thing I would do is replace it with mechanical fuel pump, about $20 at Auto Zone. You will have to reroute your vacuum wiper hose somewhere to intake, not a problem though. But will receive constant flow to carb, not occasional. I have had this problem with several AMCs before though. And all were eliminated with changing to mechanical fuel pump. Something else mentioned below by Joe Fulton is the lines.

On the 71 Matador 2 door I had with 14,000 miles, it was also a vacuum wipered car. Didn't think much of it, but was hard starting, even with new carb, and always seemed starved for gas. I put new carb on it, and new fuel pump, mechanical, and rerouted the vacuum wiper hose directly into intake, no issues. However, on the Matador, if you get under it, the car has two metal fuel lines, the first one is from gas tank sender to about right under door. Then other from same to fuel pump. There was a small, about 3 inch, fuel line connecting the two under the car near door, looked fine but had never been replaced since 1971, so when touched, it was brittle, and when squeezed, pourous! So I decided to replace the small 5 inch line from sending unit at tank to line, and also replace this small 3 inch connector, 'hidden' (because I had never seen a AMC with a connector there) line, and any fuel lines from fuel pump to carb.

I may add that I run not one, but TWO clear see thru fuel filters on all my AMCs, one of them between the frame and fuel pump in the engine bay, the other right before carb, even with tansk that I have had professionally redone, ones a year I change them out, and has never failed that the lower one usually catches something the upper one is 2nd line of defense however.

Anyhows, the 71 Matador with 'constant' flow of gas was amazing, just night and day after different fuel pump and lines. I drove that car a total of 250 miles in 11 years I owned it, but wanted to keep miles under 15,000. Still, I would take it out on Beltway 8 and open it up, and there was no hesitation and that 304cid/210hp engine simply flew. And whenever I started the vehicle, cold or hot day, simply press gas once or twice, and it would crank up easily from fuel in pot, before then it was a battle of wits and would I burn up starter before car started, or how many cans of started fluid would use before idle!

Anyways, it seems that simply changing out that duel fuel pump will solve your issues, keep us posted.

You may have a leak in the fuel line on the suction side of the pump. One possible source for the leak would be the rubber hose which connects the fuel tank outlet to the metal fuel line leading up to the pump. That short section of line may never have been changed since the day the car was made. Also, your fuel pump could be worn or damaged and might need to be replaced.

?I am needing some help with this
new car. The gas bleeds back to the tank every time I turn
off the motor. Is this normal? I have a vacuum system on my
car.. wipers.. and they are run from the fuel pump.
Occasionally.. once a week... I cant get gas to the carb..
empty filter and wont start like it is out of gas. I prime
the carb, nothing. I disconnected the fuel line to the fuel
pump and poured gas to the pump. reconnected it all and
primed the carb again.. it started and it pulled gas from
the tank. When I got to the gas station, I could only get a
few gallons in it. So... it wasn't empty after all.. Any
ideas???
