1989 245 b230 to D24t build

Cooling system is complete! Got the valves adjusted too! I went ahead and got the valve cover stripped and painted the same color as the block, I really like how these D24T's look with the valve covers painted to match the block color.

It’s been awhile since I updated the thread... car is nearly finished! I fired I up today! Yay! Had some extra work that I really wasn’t expecting, I could not get the fuel system to work with the in-tank pump, I could not pull fuel through it for some reason. So I went to drop the tank to change the sender/fuel pickup to a diesel unit.. well one of the fuel lines on the underside was rusted out! I also broke the bolt for the filler neck clamp, the joys of a 30 year old car.. So I ended up replacing the fuel pickup and fuel lines from tank all the way to the injection pump with the diesel specific lines.

Sorry for this off-topic question Anders, in your case do you also need to change/swap the fuel gauge in the instrument cluster to make it work properly with the `new` diesel-specific sending unit that you just installed? Is the fuel gauge part in the cluster also diesel-specific, partly or in any way?

(I`m just trying to figure out what to do with my ``once gasser then td- swapped`` 745 car`s annoying fuel gauge. It doesnt work correctly, it actually works the opposite way: showing empty when full... and vice versa; or not showing anything at all, until either fully full or fully empty. )

I do have four full clusters from other 700 cars,
one of them is from a 146k 1987 780 gasser v6 Bertone, the other is from a 242k 740 gasser appr 1985-88, and I have a cluster from a factory TD 1985 740. ((And I have the cluster from the 442k TD which belongs to my daily car--I DONT KNOW WHETHER OR NOT IT HAS THE CLUSTER FROM THE GASSER 1986 740 B230FT OR NOT. MAYBE IT IS FROM THE DONOR 85 TD CAR-- but I think I can see an orange wire that sits in the third spot of one electrical main joint which is glowplug related so I think the cluster is NOT from the donor td car and it simply got the glow feature created by v8.)

These 4 instr clusters look Very similar but have differences in wiring and solder connections are at various spots But the fuel gauge part looks identical in almost all of these clusters. I thought of swapping the fuel gauge part and see. But the secret may be in the fuel tank sender unit differences of a TD car versus a Gasser car?
Thank you for reading. tyt sending your ideas if too busy with the nice build. Sorry for the offtopic question again.

Update. Oh, I realized your build is not a 700 but a 200 car.

As far as I know all the 240 fuel sending units read all the same resistance full/empty.
Now the 740/760’s ect.. I do know there is different values on the senders, when I did my 1991 745 diesel swap I went to install the diesel sending unit and it measured just the opposite of the original gas sender.

The car is alive! Drove it out of the shop yesterday. Just a few little things to finish up here and there; wire the mechanical gauges for the backlighting, wire up the OD and put some miles on it before it leaves to its new home! Hopefully all the surprises have been found and I won’t have too many while road testing it.
