Hi looking to replace the front differential fluid. Any recommendations for a good inexpensive pump? Thanks,

 

I have used the 55-001 Lubrimatic Fluid Quart Pump with no complaints but now use long clear hose on a 1 quart funnel that I added a hook to, so I can hang funnel to ??, and do other things while it fills
I have a zap strap on the end of the hose, smaller size and cut end a bit, so I can push it into the fill hole and it holds hose in place, but I can then pull it out when full, and put end in empty quart bottle to let the rest drain out

Trick for either is to heat up gear oil so its thinner, it pumps easier and flows better

And put a pan down for either, as it will leak out a bit when full
