Exhaust Header Heat Wrap

Thermal tape, Heat Tape, or Header Tape. Do not use on mild steel headers.

In Theory:

Header wraps are designed to keep the heat in the header which reduces radiant heat around the engine bay.
There is a slight, if any, performance gain.

Header manufactures or even custom header makers will void any warranty claims if header wrap is installed.


Insulating the header with any type wrap will increase the surface temperature to molten levels causing metal fatigue and the tubing to crack. It will also trap moisture and a quick way to destroy mild steel headers.


Heat wraps can be used on starters, fuel lines, or wiring in the engine bay.


These headers are destroyed after applying heat wrap within two months time. The tubing nearly crystallized
preventing any welding repair. All the tubing would need replacement.

Timing cover

P/N: 105E-6059B EnFo and DORY-6019A FoMoCo. Interchange.
Note: Only difference is the tube boss is slightly beefier on the later FoMoCo cover.

Dipstick tube

P/N: 105E-6754 or DORY-6754A
Tube length varies: 3.5" to 4"
Tube length inserted into timing cover: 3"

Dipstick notches and tubes wear out, in some cases, nearly 1/8" worn off the dipstick notch.
Causing an inaccurate oil quantity reading on the dipstick. A way around this is to apply 3/8" thin walled shrink tube around the notch. Cut length 1" and adjust 1/4"-1/2" below the notch.
Note: Will also help seal the dipstick tube preventing blow by from a worn engine.

Vented and Non-Vented Gas Caps

 There are two types of fuel tank caps that are available: vented and non-vented.
A non-vented cap will cause fuel feed problems if your fuel tank is not vented. So you must use a vented gas cap, otherwise it will put a strain on the fuel pump, particularly compact solid state electric fuel pumps will fail in no time. Vented caps let in air to take up the used fuel and relieve internal pressure build up in non-vented tanks. Use the correct cap for your particular model.

Vented systems are ones that vent fuel fumes to the outside air thru either a vented cap or vented tank.
Modern closed systems are ones that reuse the vapors that fuels put off by recirculating it back into the fuel system by ways of an inline purge valve, or a type of a carbon canister system, or any other means in a closed  system thru an internal fuel vent. In 1970, Cortina MK2 in North America came with non-vented caps for a closed evaporative emission system.

Below is a list of English Ford vented and non-vented caps:

100E series:  Non-vented tank. Vented caps: EOA-9030 or Locking cap: E493A-9030.
105E series:  Non-vented tank. Vented caps: 105E-9030A or Locking cap: 105E-9030
105E Estate: Vented tank. Non-vented caps:  400E-9030A or Locking cap: 400E-9030B
307E series:  Non-vented tank. Vented cap  : 307E-9030.
109E Capri / Classic Consul.  Vented tank. Non-vented caps: 204E-9030A or Locking cap: 204E-9030B

EOTA / ETTOA: Non-vented tank. Vented caps: EOA-9030 or Locking cap E493-9030.

Water Pump Spacer p/n 2730E-8A645A

105E Pump with Spacer

Uprated W/P can be a replacement for the 105E W/P. You would need to use the matching DORY-8509B
pulley and enlarge the center hole of the fan blade to 15/16" and increase the bolt holes to 5/16".

A fan blade spacer p/n: 2730E-8A645A provided for the Cortina MK2. This part is not listed in the Cortina "C" Master Parts Catalog. The spacer should be installed on all MK2 105E type W/Ps either for metal or plastic fan blades.

All impellers should be made of metal, cast iron or steel, some after market 105E type W/P's had plastic impellers-don't use. They will come loose or melt from high heat.

204E Fuel Sender Units

EnFo p/n: 204E-9275A/B/C

For:    '59-67 Anglia 105E sedan
          '61-64 Consul Capri / Classic
          '56-62 Zodiac / Zephyr / Consul sedan.

Unit Manufactures / Type:   Float Sender Unit. Resistive wire wound Bobbin, Single Sweep.
    - Smiths T.F. 1000/23 WET   EnFo p/n: 204E-9275A
    - AC  7228816 12V D5         EnFo p/n: 204E-9275B
Replaced by 204E-9275C. I assume that T.F. means mounted on top of fuel tank-WET, submerged.
AC/Smiths units are interchangeable.

Rebuilt 204E Fuel Sender Unit
Unit Manufacture specs:    Resistive range: 12-22 Ohms to 240-290 Ohms (depending on the # of wire turns on bobbin and condition of the unit)                              
Wire type: Nichrome #34 .006 diameter. approx. 20 Ohms per foot non-magnetic.
Wire length: 14 ft. 200 turns.

Typical failures: Intermittent, corrosion, worn or damaged, and unit not grounded. Check that the unit is properly grounded to the body (there should be a ground wire from the sender unit mounting screw to the body/chassis) before removing the unit.

Removal:  Remove unit from fuel tank. Remove the access plate from the unit (two screws or two tabs) Corroded/stuck units should be soaked in a cleaning solution ( DO NOT SAND-BLAST). Discard units with excessive corrosion on the aluminum body that has worn thru. Units in decent shape with moveable parts are more desirable. Check the float for small holes or fuel inside. Repair holes with silver solder and flux, if necessary.

Corroded Unit but bobbin in good shape
Condition: Check the condition of the wire-wound resistor, sweeper contact, wire connection to the terminal. Clean the face surface of the wire-wound resistor with a cleaning solution/acid brush.

Connect a digital Ohm meter, one probe to the body of the unit the other probe to the spade connector. Move the float arm slowly from one end to the other end. A steady reading of approximately 12 ohms to approximately 290 ohms.

Corroded terminals should be removed by drilling out the rivet on the top connector side. Replace worn parts. Re-attach with a 1/8" x 5/8" long aluminum pop rivet.

Re-Winding Resistors: This procedure will require a NZ-1 winding machine. NZ-1 has been modified  to accept a bobbin. It's nearly impossible to re-wind by hand. I will show you how I accomplished this.
NZ-1 Manual Winding Setup
Mounted Bobbin wound with Kanthal
Arm removal with punch and hammer
Installing arm. Place arm in vise. Tap on sweeper stud.
Remove the arm/float assembly as shown (mark the position of the arm).
Remove the sweeper assembly (detach the braided copper ground strap, if there)
The bobbin is safety crimped in its guide. Carefully remove the safety tabs. Cut the wire to the terminal. Carefully remove the bobbin. You may have to move it back and forth until loose. Use WD-40 if needed. Remove the resistive wire. It may come off in sections. Total length 14'.

Alternative Resistive Wire:   Kanthal A1 #34 gauge (.006 diameter ) 21.1 ohms per foot. Magnetic.
Kanthal resistive wire: chromium, aluminum, Iron.

Nichrome and Kanthal cannot be soldered with a typical soldering iron, unless excessive heat was applied. So, wrap the end of the wire a couple of times around the interior terminal. Apply electrical solder to the terminal covering the wrapped wire completely with solder.

Result:  165 turns on the bobbin and installed in the unit came to 22 ohms to 242 ohms.
I sprayed some EL601 Red Insulating Varnish on the coil but the fuel washed it off. So leaving the wire bare did not effect the resistive range. Also, I didn't attach a braided copper wire from the sweeper rod to casing ground as i figure that the cover plate notch should press against the top sweeper rod for grounding. Some units had the ground strap missing or broken in that case the unit still worked properly.

Lucas Reproduction Distributor Rotors

Beware of Lucas reproduction rotors that have the troublesome rivets that holds down the brass contact to the plastic body. These are known to short circuit causing misfiring or complete ignition failure. There is insufficient insulation ( on some versions only 1/16" plastic material ) between the bottom of the rivet and distributor shaft.
The original Lucas rotors brass contact was recessed or molded into the plastic body which did not provide a rivet.
I cut a few rotors in half along side the rivet and found that the distance between the base of the rivet to the distributor shaft was only 1/16". In that case, high voltage ignitions would easily short circuit across to the distributor shaft. Most reproduction rotors do not have an inner spring clip and could fit loosely on the shaft causing it to wobble. This will make contact with the distributor cap contacts, assuming the shaft bushing is not worn.

There are quality reproduction rotors available i.e.
