GregH Posted October 26, 2011 Share Posted October 26, 2011 I have a customer who wants to have us install this fuel tank into his vehicle: Titan Fuel Tanks website part number 7020211. It is a midship fuel tank with a 50 gallon capacity. Uses the same fuel pickup and sending unit. Anyone use a product like this? Will the miles to empty reading be correct? Does it affect the fuel economy calculation? Will the fuel gauge work right? Thanks! Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted October 27, 2011 Share Posted October 27, 2011 Looks like you might be the guinea pig there Greg. The gauge operation should be unaffected. As for the DTE and MPG calculation I am curious too. Quote Link to comment Share on other sites More sharing options...
lmorris Posted October 27, 2011 Share Posted October 27, 2011 We have. They are nice to install. Make sure you torque the fuel pick-up plate to spec or it will leak. Quote Link to comment Share on other sites More sharing options...
GregH Posted October 29, 2011 Author Share Posted October 29, 2011 Thanks for the input. It's up to the customer now. If he decided to do it, I'll let you know how it turns out. Quote Link to comment Share on other sites More sharing options...
Adam_Dodson Posted October 29, 2011 Share Posted October 29, 2011 I'm willing to bet the DTE will be off. Quote Link to comment Share on other sites More sharing options...
lmorris Posted October 31, 2011 Share Posted October 31, 2011 I'd be more willing to bet that his fuel comsumption gauge will be out but DTE may actually be close. IIRC, DTE is calculated using average consumption and tank level. With the larger tank and the fact that the PCM is calibrated to the stock tank, consumption will actually read as lower than what it really is. This should calculate DTE as higher, which should coinside with the tank size. The new tank is longer as well as deeper. I wonder if it will start setting overfull codes, as the actual level in the tank will be higher than the float can go. This may also throw off readings as the truck uses the fuel from a full tank and no fuel level drop is not detected. Then again, the customer may not give a crap what the readings are as long as the lower portion of the tank reads correctly and he gets some extra miles per tank.
