About the Racor installation:
You could mount it anywhere pretty as the pump is doing the work and you will have no worries about fuel drawas the tanks is elevated above the pump.
The you could mount it on the rear of the tractor if you have room on the left side if the remote(s) are on the right side or vice versa.
An even better safer option is simply bolt it to the ROPS if you do not have a hard cab and be sure to use the mounting bracket AND driill through the ROPS and use washers and NYLOCK NUTS-lock washers wont do it.
You will need a bit more hose but thats no problem as the fuel line will be easy to route through the frame and you can correct any possible binding areas by using loom clamps for the feeder line and return line
Fuel flow is not an issue and you will have a beter tractor for your effort.
The 2 micron filter will allow you to protect your engine and fuel system and reduce the smoke too.
You will use a few more filters but the protection is worth the expense as the filters are the same size for all the 1100 model units.
no worries use the rops and the filter will be safe and cozy.
Be sure to mount it on the inside edge of the rops to avoid and chance of banging it with something (if room allows and you can safely control the tractor with it on the inside edge of the ROPS.
If You mount it on the rops be sure to have a coffee can handy to drain the water and dirt/crap into to avoid staining the fender.
