Thanks that is the exact info I wanted on the sender. Now where do I get one that was the truck kind.

Thanks all for responding. Yes I am trying to get both the mechanical Tach and speedometer's running on the MGTD dash. They both have operating cables coming from them which both respond to turning. I spoke with a guy in a local speedometer shop and he is more focused on repairing the units. I have heard there are adapters but need a source for them and probably a place to change leghhts of cable. I see a brass removable nut at the rear of the engine near the firewall about 1/2 in diameter. The speedo guy said he thought many tachs would run off cam and there should be an access point there. AS it looks liek this nut was added after ( the engine is painted but this nut is not) I think it may give access to a square hoel on the cam designed to take a cable. There may also be mechnical access on the tranny for Speedometer but I don't know where it may be.

Nissan parts guy looked at me like I had two heads when I said I needed info on an A-14 engine... I said, " There you go -- Built in Obselecense!!! DOn't you expect your cars to last 30 years? What kind of junk are you sellling now?" :)
I could use after market -- just not sure how close they'd fit in dash ---It is not like I am racing it-- The engoine may go 70-80 but the frame and suspension would stop about 65 mph.

I have an A 14 engine in a 1953 MGTD. I am trying to connect guages.
A picture I have of a sending unit shows a "t" type fitting withone part going to the ideoit light tbut the other leg set for a pressure like. Any Idea where I might get one like that -- I only have the one wire idiot light now.
2) I have the engine serial No is there a way to find what car it came in?
3) Can I get an engine manual for this A 14 Engine?
4)Any suggetions con connecting the currently operating MPH cable from Tannny to my dnaglein gMPH cable from Dash.
5) ANy suggestions on where to connect my TAch cable which runs from Dash.,
