Anyone running an RB motor or any of the other popular EFI swaps probably looks to the early EFI S30 tanks as the easier way to make that happen. That is one reason I would consider all options to salvage the tank you have... Link to comment Share on other sites More sharing options...

Can't say for sure but the 240 tank has some extra vent nipples for the the evaporation tank. Maybe they could be plugged? EDIT: After seeing Wheee's picture with the big hose at the back, the early 280s have the evap tank also. Maybe they all have them, I just don't remember one on my '77 tank when I cleaned it.

Yes I believe so, the 280z tanks have larger diameter supply and return ports than the 240z tank. I haven't tried the swap yet, but I have examples of both here. So I can't comment on what the differences are... Link to comment Share on other sites More sharing options...
EuroDat Posted January 30, 2016 Author Share #20 Posted January 30, 2016 (edited) When I was doing my 240Z bumper mod I noticed the horn mounts are different on the early model. HaZmatt was in the middle of his restoration when I noticed it on his 280Z. He has a 75 model and I have a 5/77. I think its somewhere late in 76 they changed this. Might be when they changed the bumper design. The early design has brackets for the horns. The later uses tabs on the bumper shocks.

wheee! Posted January 31, 2016 Share #21 Posted January 31, 2016 Mine is the same as Hazmatts. On the lower rad support. Or would be if they weren't cut off already... Patcon? Updates? Link to comment Share on other sites More sharing options...

EuroDat Posted February 16, 2016 Author Share #24 Posted February 16, 2016 Here are the two different style AFM's. The main difference is the Fuel pump switch. There are some other small differences in the AFM body like extra webbing on the outside, but I don't think that make any significant difference in functionality. Models with switch: 22680-N4202SV - up to july 75 22680-N4210 - Aug-75 to Jul-76 22680-N4800 - Aug-76 to Jul-77 Models without switch: FED: 22680-N4211 From Aug-78 CAL: 22680-N4801 From Aug-78 280ZX 22680-P6600 I don't know what the difference is between the two FED and CAL models. Unfortunatly the models before Aug-77 don't have the Nissan part numbers on the AFM. The stickers come from JECS and will have a number similar to this: Type: A31-625-000 Serial nr.: 1X21 Engine size: L28 Somewhere after Aug-77 they started using the Nissan part numbers as well on the stickers. 1 Link to comment Share on other sites More sharing options...
