TR7 Sprint heater hose

TR7 Sprint heater hose

My TR7 Sprint has its heater attached to the engine via some custom plumbing. Here is a picture of the hoses that link the pipes thru the bulkhead to the custom pipe work. Do these look like the normal heater hoses? Are they available separately? I wonder how much are they?

I have tried using lengths of straight rubber but that does not work as the ends to be linked are not inline and there is it not enough room to use a curved straight piece, so I need a hose that is curved as shown in the photo.

They connect to the steel heater pipes that come throu the bulkhead at one end. At the other end having passed to the inlet manifold side of the engine they connect to more metal pipework that in turn connects to the manifold etc. Here are some more pictures to show the detail.







I suppose I may end having to fit a Sprint adapter plate. I want the car back on the road so have refitted the old hoses for now.

Here is a picture of a Dolomite Sprint engine (thanks Beans http://tr7beans.blogspot.co.uk/) Seems this the basis of the heating plumbing on my engine.

Swapping out the heater and mystery wiring

TR7 dashboard area showing interior with heater out

This morning I got the heater out.  A quick call to Rick at S&S Preparations showed that I had missed a couple of fastening that go throu the bulkhead.  To be fair they were covered in a layer black stoneguard so were not easy to see.

Getting to the heater box has meant taking all the fascia out.  To get the fascia out had remove the lots of other stuff/trim: the a-post covers, the switch panel, the gear lever console, the steering wheel, the instrument panel, the drivers seat. As my car had various extra had to disconnect the radiator fan override, some of the radio wiring, disconnect the oil pressure gauge from the bottom of the fascia.

Whilst the car is in this state I will able to investigate the mystery extra wiring.  There is a hidden key/ignition switch which is wired into the ignition loom - trouble is I do not have the key - the switch was well hidden I only found it when I was in the footwell looking up.  The flick switch to the left of the steering is still a mystery - it is linked into the radio wiring - which is a really complex bunch of colored wires - think I will leave that alone as it works.  Intend to add a proper separate earth for the radio rather than continue to relay on it being lopped into the earth on the back of the rheostat.

TR7 Wiper blade fitting

I need to fit new wiper blades but most traders now only stock click fit style.  As can seen from the picture above the TR7 wiper blades attach via a pin.  The TR specialist I contacted did not have any in stock -  I saw some advertised on eBay which promised to include a fitting kit and were advertised to fit TR7 so I ordered them. Unfortunately the was no fitting kit so still no fix.. Am waiting for the eBay trader to sort it out. Have put up this post so I can refer them to the picture to show them the problem.
