72 220d stc

i have a 72 220d want to put stc,your ready to install stc is mostly for 123,you state 115 chassis is difficult because of battery.can one put filter-vfm on passenger side of engine bay and route longer hose to ip pump etc with insulation on hose.is that the major stumbling block? do you recommend specific insulation on hose? also does veg oil remaining in engine at shutdown cause coking with cold start in the morning?

SVO Fuel Conversion Specific Aid

Chassis Model Number

W115

Fuel filter.

I added all kinds of hose for my w126.I insulate the warm fuel lines with foil,and aluminum duct tape(the metal kind).

STC 1000 / 2000 will not fit

My pre-built STC kits will not fit on either side of a 115 chassis without extensive modification (which defeats much of the value of having it pre-built). I would recommend the STC 100 kit. That will allow you maximum modification and customization. My manuals on SVO conversions go into deal on the causes of coking and how to minimize the problem. Kent

yes ,i understand your pre built kit will not work in this chassis,but is major modification hose routing and mounting filter and vfm?.i want to use your kit but want to know what im up against.

It certainly can be done

The STC 1000 comes with all the components correctly aligned to the chassis it is built for with all fittings pointing in the correct directions and all hoses pre-cut and attached with the proper lengths to hook up to the factory fuel lines and engine. The instructions are also specific to the 116, 123 and early 126 chassis diesels.

If you choose to install it in a 115 chassis you will most likely have to remove all the hoses, then remount some of the components to proper orientation, modify the brackets and cut new hoses to route to your engine and factory lines. Since the instructions will not apply specifically you will have to interpolate. If you decide you want to go this route you could purchase extra bio-spec hose with the kit to make sure you have enough. We have it (5/16) in 8 foot lengths - one of these should be enough.
