Thanks a lot! Will cleaning and tightening the union require bleeding the fuel system? (Not sure how the pig tail pipe connects on the inside.)

After recent oil changes I noticed that my Dexta is leaking fuel when running. The pig tail shaped leak off pipe from the Simms injection pump is dripping every 5 or 10 seconds (I collected about two spoons of fuel in half an hour), and there is also fuel dripping from the flat bottom of the injecti...

Ah, will keep that in mind. Anyway, now we are running again!
This was a fantastic learning experience. Thank you all so much for your kindness, sharing your knowledge. Me and Dexta have now reached a new level in our relationship...

So... bleeding again. Now I see fuel pouring out at the bleeding bolt on the injection pump as I push the manual pump. If I tighten it and open one, or all three, of the outlets on top of the injection pump, I see fuel ready to enter the pipes leading to the injectors, but there is no movement here ...

Many thanks for all advice! As soon as I get an hour off I will start the bleeding process all over. Update coming...

Interesting. What is a starting cup?

Well I used to have the primer, but never used it since I wasn't aware of the function. I don't think the previous owner used it either, because when I asked him about the fuel pipe between the tap and the glow plug he didn't know what it was for. No, I'm not sure I bled the fuel system properly. I ...

Asked the seller about outlets, and got a picture from another angle, showing a hole on the other side of the primer button - for connecting a pipe to the manifold!

Oh, got it. Mine doesn't look the same. I'll post a picture as soon as I learn how. I find this primer tap on many sites, with pictures at different angles, but there doesn't seem to be any separate primer outlet: https://images.app.goo.gl/9wx4HXaULdP8HXFY9 So what happens then, when the primer butt...

Thank you for your input! I have used this Dexta for five years without knowing it had the primer function. Sometimes it has been a struggle to start it, but not like this. I am afraid I broke the old tap into two pieces while I removed it so I can't put it back. When I look for "Dexta fuel tap prim...

My Fordson Dexta will not start. The start engine is running happily, turning the fan like it should, but the diesel engine will not start. I’m not sure what to try next. Background: This winter I realised that the fuel tap under the fuel tank was leaking a lot, so I ordered a new one from a parts s...
