So my dad and I are fixing a boat diesel engine. We had it working but injection pump got folded (guy who was to make sure that the boat didn't sink when we were away messed up). Dad tuck it apart to clean it but after assembling it, the pressure doesn't build up in it. We looked for a detailed manual but the part we are after wasn't described well enough in the diagram, we called local office of the product thy told us that don't have par to sell since the engine is so old. We also tried the mechanic that works diesel marine engines, he told us that it hopeless and it'd better to get a new engine or just sink the boat. The mode of the engine is Saab diesel g1. If any of you guys knows anything about it, me and my dad would be really thankful.

I wonder if parts from there would be adaptable. India produces these and others like them brand new.

So its a 1 cylinder? Didn't those old diesels have a pressure release that was used to help them start up?

They do but OP seems to suggest the injector pump is not producing pressure.

I'm going to take a guess that this is a SABB (not SAAB) engine. If so the service manual is here:

Also, the company website is here:

They should be able to tell you if you have any chance of finding the part.
Good luck!

OP here.
The injection pump was in working order before we dissembled it. But it doesn't hold pressure now after putting it together. So we are assuming that it can be fixed without getting new parts. picture related its the part we tuck apart for cleaning .

Yes, that was it. Thanks

Have you bled the fuel system after refitting?
Did you replace any gaskets/seals in the pump when you stripped it down, as they generally can't be re-used.

>> No.674680

>>674391
Yes, we did. The seals were in good condition so we used them. I'll look for new ones and see if that helps.
