### ⭐⭐⭐ 







  
  
    Love my GWL11. Easy pump to replace. Seems like a genuine part
  

*by V***P on Reviewed in the United States on August 18, 2020*

F& P washers are exquisitely well designed for casual handyman level user replacement of their wearable component parts. Our pump motor gave up recently (10+ years service) . this piece is a nearly tool-less drop in replacement part. you will need a Phillips head screwdriver, possibly a set of needlenose pliers if the bladed wiring connections are stubborn. there are several vids on YT that attempt to show service/maint of these pump motors. Most are flawed, but they do correctly show removal and installation procedures. That is all the info you need with a new motor in hand. FWIW, much of the bearing problem that causes the squeal/screech can be addressed. Motor can be fully disassembled to free up the bearings. these bearings are Oilite beads and can be "refilled" with straight nondetergent oil using a vacuum pump brake bleeder reservoir. but for a C-note, the new motor provides peace of mind. same ease of repair comments apply to F&P diverter valve assy install and the basket suspension rods if you ever need to take on those tasks.

    Saved over $40 each by ordering these!
  

*by J***. on Reviewed in the United States on March 30, 2015*

These are identical to the $45 unit sold for soil density volumeters by that well known H-company. The pressure fittings from your old pump fit over the nylon fittings on these bulbs and you save over $40 each! DUH! Advice for all: put a string or elastic band on your pump bulbs to keep it out of the dirt and you won't have pump failures. The tiny silicone valves in all of them can NOT tolerate even a grain of sand.

### ⭐⭐⭐ 







  
  
    Pretty low vacuum
  

*by C***Y on Reviewed in the United States on November 2, 2013*

It work fine with water but we bought it to pump fake blood in a Halloween prop. The fake blood was not much thicker than water and the reservoir was only 32" below the table with the "patient" but the bulb vacuum was not strong enough to move it satisfactorily. It took 5 to 8 minutes to expand back to about 50% capacity and then did not fill more.
