    Musso Filter Heater

    I am thinking of putting a heater around my Musso's fuel filter.

    Has anyone already done this or could suggest a simple method? Should I go 12V heater pad or something t'eed off the heater hose?

    Much easier to put a heater in-line with the fuel supply to the lift pump. Get some 5 mm OD copper pipe and some 19 mm OD copper pipe and 2, 19 mm ID tees. Silver solder the tees onto a piece of copper pipe ~150 mm long so they each have one end of the top of the tee onto this piece of copper pipe and add a 30 mm piece of 19 mm copper pipe to the leg of each Tee and to the other end to the top of each tee. Thread the 5 mm pipe thru from one end to the other, crimp down the 19 mm copper pipe onto the 5 mm pipe at both ends. Then silver solder the fittings together, making sure all joints are water tight.
    connect coolant pipes to the 19 mm pipes and fuel hoses to the 5 mm pipes. Bleed air out and start the engine. The coolant will heat the fuel in the 5 mm copper pipe on its way to the lift pump and thence to the fuel filter.
    Basically, the 5 mm copper pipe takes a straight path thru the 19 mm pipe, the coolant comes in and out of this heat exchanger from the side ports.

    Not hard to make and simple to connect (heater hoses go to the firewall on the LHS of the engine bay)
    Best of all it is easily restored to stock if you don't like it, or if you wish to transfer it to another vehicle.

    Thanks Tony,

    Do you have a picture of one?

    Have a look here.

    Condenser, heat exchanger ..... same thing.

    Re: Musso Filter Heater

    I thought about this today and if you do not need a lot of heat, then recovering the heat from the return line would help raise the temperature of the oil going to the fuel filter.
    You could use 2 copper pipes of the same size (5 or 8 mm OD depending on the fuel hose ID in your vehicle). Simply bend one end of each pipe so that when they are joined, you can get a hose on each end of each pipe. Solder the copper pipes together. The hot fuel returning to the tank heats the oil coming from the fuel tank by a few degrees (I have not done tests to quantify this).
    If you really need to ensure that the fuel filter is kept clear of solidifying oil, then the heat exchanger in the post above would be better.

    Thanks Tony, I still can't picture what you are meaning. I know there are simple pipe heat exchangers you can buy but they are too large (1"). Maybe a 12 plate heat exchanger would do the job?

    I built one using 3/4 and 1/2 inch copper, readily available from Bunnings or any other hardware shop.

    Here's a pic. Click image for larger version.

    It consists of 6 pieces. The 3/4 tube, 4 pieces of 1/2 inch tube, and 2 reducing T's. To get the straight through 1/2 inch to pass through the reducing T's, it is necessary to slightly file the hole larger. The rest is just as it appears.

    This can be installed to take coolant in one pipe (use appropriate sized copper pipe for heater hoses) and fuel in the other. In this case the fuel copper pipe needs to have a bend at each end to allow fuel hoses to fit (harder to bend the larger pipe than the small one).

    That makes a lot more sense now. Off to Bunnings. Thanks Tony.

    I did also see these. They have good internal surface area but too big for a vehicle.

    How did you go making one?
