Good morning all, hello, I am new to the forum and looking forward to testing your knowledge and experience of our newly acquired genuine "barn find" 924 Turbo. This is my first Porsche project and i'm looking forward to it. Over the years I have worked on a number of different cars and have found no better workship manual than the "knowledge of the crowd!".

So we acquired the turbo from its previous owner having had it dry stored for some 17 years. It's pretty much complete - albeit completely stripped and in boxes! The car also thankfully came with a tonne of spares.

it wasn't until we got it back to the workshop that we found the underside had been completely rebuilt, it is like a new car underneath will all bushings, brake lines, fuel lines, suspension components and brakes and completely rust free. So very very pleased! Interior is choclate brown, all leather tomb stone seats tcomplete with alll original interior parts too.

Not rushing the "will it start" (those videos make me cringe!) we set about working through the basics. We went to drain the tank of old fuel, only to find it had been dry stored with an empty tank! There was some residual fuel left in the lines to the tronic system. So, we popped out the sender and used a borescope and the tank appears to be rust free. The lower part of the tank had some residue, but overall it was in good shape.

The in tank pump appears to have failed. It's the ridiculously expensive one.
The in line pump appears to have failed. Both look like the original parts.

I have SO many questions, but before I get into those, I would really like to get the full low down on replacement pumps. So far from my research I have come across and read up on a number of suggestions:

1. Replace in tank with 944 strainer and fit inline pump
2. Replace both pumps OEM
3. Replace in tank with 944 strainer and fit upgraded inline pump
4. Leave old pump and fit upgraded inline pump

I'm leaning towards number 3. What I am really looking for is for peoples input who have done any of the above, pro's and cons and if they have upgraded pumps, what brand / output pressure did you opt for? Any starvation issues or fuel pump relay nuances I need to be aware of?

Thank you!
