Bosch fuel pump dies at 4.5 months old.

[johnj92131]

On the last Friday of January this year, I had my Amazon purchased Bosch electric fuel pump installed in the Comanche.  On Thursday, the truck died and I had it towed to the shop.  First thought was a bad Crankshaft Position Sensor, but turned out to be low fuel pump pressure.  Started at 35 psi,, then quickly dropped to 5 psi.  Truck died, wait a few minutes and the truck starts with 35 psi fuel pressure and drops off to 5 psi again. So the shop replaced the fuel pump and the truck is running fine again.  Replacement pump came from NAPA this time.

 

Just real surprised to see the Bosch pump only last 4 and a half months.

Was this one of the Amazon Warehouse Deals pumps John?

Truck had 3/4 tank of gas when the pump died.  But I tend to run the tank down to just 2 to 5 gallons between fills. So maybe I contributed to the failure.  Have to say I was very surprised about the dead pump.

 

 

Don, Yes it was the Amazon Deal pump.  It looked just like new, packaging was damaged.  So I did not think it was a second because of pump function.  I was told the pump may not have been made in Germany, but made in Brazil, even with the Bosch name.

 

It is just getting harder and harder to find good quality replacement parts.  Problem is that we all want a Walmart price and with that Walmart price comes Walmart crap quality. My long time shop was telling me even wheel bearings from most suppliers now are CRAP/junk/low quality now.

Crap. I bought one too for a spare. The packaging was perfect on it though. We'll see when replacement time comes. But I've had this same Bosch pump on my rig for over ten years now and it's still doing fine.

I just replaced mine, Bosch. 

 

Once I installed a pressure gauge I realized that when I blipped the throttle the pressure would drop from 14lbs to 8lbs, so I replaced it. 

 

Now it drops from 14lbs to 12lbs for a split second, IOWs the new Bosch barely keeps up. 

 

Not impressed. 

 

Also, it came with no hardware and was NOT OEM in shape, I had to adapt  the brackets to make it fit.

Just one of 62 reasons I plan to repower, AMC/Chrysler support is becoming nonexistant.
