thanks
Surplus Center S41-2
should fit if I have read everything right

edit: those purchased, 1/4 hose and single 5k psi liquid filled gauge ordered. gauge set for plows/bobcat will be sep order under company when needed.
many thanks to all involved here, very good info.
now wait for shipping and then test pressures. flow rate seems ok, empty from full down to full up at 2600rpm is, by mental count, 4.1 seconds which is VERY close to manufacture spec of 3.7.
just initial breakout when bucket is in loam/compost pile is issue. tilt and reverse few inches helps but suspect (by looking at adjust screw) this has never been checked and I may be on low side

I ordered a liquid filled gauge and couplers from kensboltonhooks.com

He seemed to have fair prices and enough of what I needed for my GC

EDIT: looked in wrong spot there when looking for gauge my fault.
I already had some items in cart from amazon anyways got gauge and hose for 30$ free shipping just added to cart and hit buy now button. as far as couplers have not had chance to pull bucket to compare to chart I printed off from his site, and since I had a known part# just went with it. bought 2 for 9$.
got his site saved and will check there for stuff for sure.

isn't it boltonhooks.com ??

Check stamping (part numbers ) on existing connectors..... NOT that there may be anything wrong with Kenny's information, but somebody here found out that MF changed coupler sizes at some new model year a few years ago...

They changed later. I have 1/4" and I believe they went to 3/8" after 2017

1910 psi at 2600 rpm tested on blue line.
not touching it
am more used to the DL95 with the heavier lift capacity. just got to learn how to use the dl100 correctly.

The DL100 is a nice heavy loader but it's shortcoming was lift capacity. If you had the pleasure of a DL95 and then went to use a DL100 it almost feels broken lol
