I just purchased a Realm/RAM D-Type. Anyone know the capacity of the fuel tank? I’m hoping my fuel gauge is way off. It went from full to empty in about 70 miles.
Heavy right foot??
drive until it stops and see how far you get?
Peter Crespin will probably chime in with a more sensible answer.
Can you not measure the dimensions of the tank and calculate…From memory a Realm C is about 70lit
The already completed D-Type was purchased at auction, so not sure that I could measure dimensions of tank, but of course, I can drain and re-fill to get approx… capacity.
Hi Glen…on a Realm C type you can see the tank if you look up through the rear wheel arch & measure(wheel removed)…is that not the same with the D…Steve
15 Gallons, although I wouldn’t suggest topping it off to that level.
Thanks to all. Net chance I get, I’ll measure the tank or volume to be sure what my car has. I may even try to get that info. out of RAM next time I’m over there.
Thanks again….
Glen - it’s 15 gallons, I have one too 
Ok, thanks for the info. So, I’ve gotten 12-15 gallons numbers so far but it will be awhile before I can look closer into this issue. Until then, I’ll trust a stick over the gauge.
Thanks, again, Glen…
Because the tank is wide and flat, rather than deep, any tilt from level has a big effect on the gauge reading or even a dipstick. The float hardly moves from full to empty. The best fuel gauge is the trip odometer.
Thanks Peter…
Soon as I get back from UK, I’ll have a chance to better ‘calibrate’ my fuel consumption and capacity.
What was the capacity on the real ones, back in the day
30-40 gallons perhaps?
The spec. I found had fuel cap. at 37 - 44.4 gals. (assume that was UK - US gals). Not sure if that was a fixed or rubber tank spec.

Just visited Realm Engineering in the UK, and chatted with Adrian. He says his tanks were 15 gal. capacity, but I forgot to clarify if Imperial or U…S. gallons. If I had to guess, I’d guess imperial.
Hi Glenn…definatly imperial…are you at the E60 event…was there today. …and will be tomorrow…Steve
Sorry I missed you. I was there with the only California car but now back at hotel. Tomorrow, we join a E-Type tour to Wales for the week.
Some nice looking D-Types at Shelsey Walsh. Unfortunately, my E-Type was having some minor problems and never got up to full speed up the hill. And that’s after spend a few $$ to get it ready for touring this and last year….
