jbenajes Posted March 6, 2014 Report Share Posted March 6, 2014 Hi all, I wish to fabricate a dipstick for the TR3A fuel tank level, to back up my suspicious fuel gage (even after several attempts to calibrate it). Can you help me with the required data of fuel volume versus level height on the dipstick? Thanks in advance. Jesús Quote Link to post Share on other sites
john.r.davies Posted March 6, 2014 Report Share Posted March 6, 2014 If no one can advise, Jesus, do it empiricly. Run the tank down as low as you dare. Take a stick with you to the petrol station. Fill with five litres, dip and mark the stick. Repeat, until tank full. Voila! Not my idea. I've sen many race cars with calibrated dipsticks in their boots. ohn Quote Link to post Share on other sites
McMuttley Posted March 7, 2014 Report Share Posted March 7, 2014 agree with JRD, I have done this for my equally unreliable 3A gauge after getting tired of filling up every 50 miles or so and developing PFS OCD syndrome. (we also use the same system for fuelling the formula fords with the minimum necessary (weight n all that) - round dowel with notches personal to each car. With 5l marks, you should get around 9 or 10 notches - which helps to assess whether you have 30%, 50%, 70% on board ! If like my local busy PFS, which is always full dawn til dusk since it became an M&S (and is on a unnerving slope) and you can't take your time to fill and mark, borrow a large jerry can for the 5 litre a time fill at home. PS Ideally have a cross bar or handle or something on top of the stick - its a bugger it it falls in the tank and has to be retrieved ! PPS be careful not to clout the float/arm Quote Link to post Share on other sites
BlueTR3A-5EKT Posted March 7, 2014 Report Share Posted March 7, 2014 I carry a 5 litre can filled with go go juice. Cheers Peter W Quote Link to post Share on other sites
jbenajes Posted March 7, 2014 Author Report Share Posted March 7, 2014 Thanks for the responses and the practical recommendations. Actually, what I intended with my post was getting the data from somebody who did the dipstick calibration and waiving the petrol pouring fun at home. Jesus Quote Link to post Share on other sites
Lebro Posted March 7, 2014 Report Share Posted March 7, 2014 It is actualy not that difficult to setup / re-calibrate the fuel guage to the sender. I had to do it to mine last year. Won't go into it here , but if anybody wants to know how to do it, let me know. Bob. Quote Link to post Share on other sites
mike3md Posted March 7, 2014 Report Share Posted March 7, 2014 My first car (prewar Morris 8) had a useless fuel gauge, so I used the starting handle to dip the tank! Mike Quote Link to post Share on other sites
