2 Questions in one post
First off, how can I tell what kind of sending unit I have in my fuel tanks? I want to replace the HUGE fuel gauge in my dash with a small Autometer gauge and then put a tach where the fuel was. Can I just put a digital multimeter on the gauge and have one tank empty and one tank full and test the ohms on the empty tank and then flip to the full tank and test the ohms there? Then I should be able to get a gauge to match those ohms right?
Second question deals with gearing. I want to put 3.73 in my pickup to get rid of the 3.40's that are in there right now. It should help my towing power. Now, I have never touched a rear before so bear with me. How hard is this to do? I have pulled axles and the carrier assembly out of a S10, but never replaced the ring gear or anything like that. I just worry about the backlash and such. How hard is that to get right? What all do I need to know about the rear? Right now I know that it is a 10 bolt. I have pulled the cover and checked. Am I safe to assume that the front is a 10 bolt then as well? (I know that if I replace the back, I need to replace the front) I have been toying with the idea of posi to help with the off road use this pickup sees as well. Would you use posi on a vehicle that is mainly a tow vehicle but does see off road use primarily in the winter months. Can I put posi in the rear and not in the front? Or should I put posi in the front and leave the rear? Or would you do both? Okay so the second question is actually a bunch of questions! ![]()

First question - Yes, you should be able to do that. The range should be close to zero for one measurement, either full or empty, I can't tell for sure because I've never measured mine.
Second - I wouldn't put a posi in the front. I have a posi in the rear of my Suburban and it's great in the snow, even in 2-wheel mode. As far as setting up the rear end, it takes a fair amount of talent to do it right. I thought about doing mine, but after talking to a few people, I've decided to let a pro do it since it's my daily driver and I can't afford any mistakes! You need to set the pinon depth first and, according to folks I've talked to, you need some pricey tools to do it right, but I'm just telling you what I've learned. I'd put a master bearing kit in it too. |

1) you need a 0-90Ohm gauge. Everyone typically lists them as a GM gauge for the fuel.
2) It isn't that hard if you have the tools and knowledge to do it, but if you are unsure, I would leave the setup to a professional. 3)are you going to be wheeling alot and need a Limited slip/Posi in the front. If not, I would skip it. They are going to cost you a bundle. In the end though it is your choice.

i regeared a ford 9, not hard to do at all, just followed along with the manufactorors instructions, and yes a posi on the front is almost manditory, think about it, a posi would make both wheels spin, and if you are steering with the front, you need both of them to spin, not just 1, the rear, you could add a posi to the rear as well if you wanted, not any real point to it i know of
