Hi Max, I did the replacement yesterday evening -- ended up removing the FH after realizing this was NOT going to work leaving it in place on the side of the engine. After getting the snap ring out - not easy - coaxing (forcefully) the nozzle part out, I found the large o-ring is in

I think it diverts the fuel to flow through the other two lines, which make a pass through a heat exchanger filled with engine coolant. Max Dillon, Charleston SC ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To

I kept calling it a Fuel Heater - the official name is a Fuel Thermostat. Sorry - but from your description I wasn't too wrong... Hmm... so I need to find that heat Exchanger - for my own curiosity -- there's certainly lot of stuff in there.. ;-) Glad the leak has been fixed... my next

heat is added and not sure of the purpose of the piston. The piston probably has a wax-filled portion with a pin, same as the main coolant thermostat, and the windshield washer fluid thermostat. I never found any hoses that might add heated coolant to the FH, BTW. Engine oil is also hot, as

There is a heat exchanger in the hot coolant line to the heater core. The fuel thermostat diverts the fuel through the heat exchanger when it's cool outside. Keeps the viscosity under control in the IP and prevents the tank filter from waxing up in very cold weather. Peter

Thx Max - So... i will remove the snap ring and the nozzle will slide out? i assume the larger o-ring is closest to the hose nozzle and the smaller goes toward the rear of the FH? Thanks again, Larry On 6/24/2014 7:30 PM, Meade Dillon wrote: Larry, Did this job on my '87 300TD years ago,

Hi All, I picked up the correct o-rings from MB along with a meter of the fuel line (they only sell it in 1 meter or more lengths) that runs from the pre-filter to the T'stat (at $38!) but I figured if the hose would last as long as the OE hose that was fitted when the engine was put

Larry, Did this job on my '87 300TD years ago, as I recall the working parts are quite boring. Not a whole lot to it. The interior assembly slides out, be careful to keep out the dirt. I also replaced both o-rings, the interior o-ring probably was fine and didn't need to be replaced. Max
