More dismantling : radiator and fuelpump

So yesterday I removed the radiator. Last time I noticed and mentioned these two lines going to the bottom of the radiator. I was wondering what purpose it served. With help of the repair manual, see blog:

I found out these are cooling pipes for the automatic gearbox! This repair manual is very useful and provided me much insight about various items and the engine.



So when removing the lower hose quite a lot of coolant came out, more then I anticipated. And the coolant looked good as well, no sign of contamination.


 The airco condensor looked pretty good as well:


And of course our rodents stuffed the place with more nut shells:


The radiator also looks to be in very good condition:


A special tappet mounted:


In order to access the fuel pump I had to partly disasemble the alternator. It's still fixed and connected but lifted up and strapped with a tyrewrap. When removing the first gasline hose I was very surprised to see some gas came out (very smelly)




For a moment I thought they had spreayed the screws blue (just like the engine) but of course this was likely locktight glue :-)


And with the fuel pump removed:


It's still in working order. As a result I squirted my shirt with gas when pumping the lever. I didn't expected this much gas was still in there after 30 years! And it was very smelly, yuck. I wonder if this old gas still works - I doubt it.



Since the fuelpump is working I'm wondering if there is a need to have it replaced. I was expecting it to be seized, polluted/gummed, seals deterioated, etc. But likely the gas in it preserved everything nicely. Then again, for 12 USD you have a brand new one.

The following link provides a good insight on the functioning of the fuel pump:

I guess it's best to get a new one in and avoid potential future hassle.



Unfortunately I couldn't get the thermostat housing off. I need to buy some other tooling. Same for the fuel line going into the carburettor. I need to buy matching English sized wrenches. I do have some but not these specifics …
