#$&* '74 fuel pump issues
PART I
Week or so ago went out to fire up the 911 and blast around some back roads. It was very hard to start and ran really rough when it did start (had been running great). As I backed out of the garage I noticed a large wet spot on the garage floor, killed the car and - yep it's gasoline. Turned the key to on and sure enough, the fuel line from the pump to the accumulator was leaking near the swaged rubber hose to metal line. Pushed the car back into the garage.
Yesterday I removed the bad line (this was the only original fuel line left on the car - not a smart move). To remove it I had to unclamp the fuel pump and pull it down from the shelf in order get at the clamp on the banjo's barb. Dremeled off the swaged sleeves and put new high pressure hose on with good fuel injection clamps and reinstalled the fuel line..
When I went to start the car, the fuel pump was very loud and making a kind of rattling/swishing noise and is not pumping any fuel at all.
Question is: did I damage the pump somehow in replacing the line or is this just a very strange coincidence of bad timing that the pump picked this exact moment to go out? This is the original pump with 150K+ miles on it. I double checked everything, there are no pinched hoses.
Anyone else experienced anything like this?
PART II
After extensive searches of this forum, my options for bad pump replacement appear to be:
original OEM '74 pump - $850+ (not gonna happen)
rebuilt '74 pump $300+ (never had much luck with rebuilds)
replacement Bosch pump $250 and requires modifications
Walbro pump $120 and requires modifications
Anyone know of any other or better solutions ?? I try to buy all P-Car parts from our host but that's a big hit between the Bosch and Walbro...
thanks
