BigBrother-84 Posted March 9 Share Posted March 9 Hi there! I plan to drop the fuel tank this spring (or summer. or later this year. as usual.) Big Bro's sending unit is fluctuating a lot. Did all the tests, and everything looks good, so the sending unit is my next stop. I am wondering why JBG offers two models, for the 19gal side tank. Just the stainless steel difference? Any advice? Or maybe other suggestion for very good quality sending unit? Hey, I prefer to pay more and avoid dropping the tank once a year. Link to comment Share on other sites More sharing options...
viven44 Posted March 9 Share Posted March 9 The top one looks like its for the rear tank Link to comment Share on other sites More sharing options...
Gary Lewis Posted March 9 Share Posted March 9 The top one looks like its for the rear tank Right. 30379 is rear tank, 30387 is side/midship tank. Link to comment Share on other sites More sharing options...
mat in tn Posted March 10 Share Posted March 10 Right. 30379 is rear tank, 30387 is side/midship tank. not only does it say it's for the rear, but it is also a d9 coded part number, was that part carried over to the bullnose or is there a typo? I'm dealing with this issue also. the sender that I put in 16 years ago is acting up so I may be replacing it soon. Link to comment Share on other sites More sharing options...

I didn’t know that the rear tank is also 19gal, so I didn’t pay attention to the description. Link to comment Share on other sites More sharing options...
mat in tn Posted March 10 Share Posted March 10 Thanks Gentlemen! I didn’t know that the rear tank is also 19gal, so I didn’t pay attention to the description. I have seen them listed as 19 and 17. I cannot say that I have ever seen a 19 as I have never been able to put more than 17 in any that I have touched. Link to comment Share on other sites More sharing options...
scbill Posted March 10 Share Posted March 10 I have seen them listed as 19 and 17. I cannot say that I have ever seen a 19 as I have never been able to put more than 17 in any that I have touched. My truck is a 1983, F100, 4.9-AOD long bed...how do you know if it's a 19gal, or 16gal tank? I'm thinking short bed=16...long bed=19. Thanks, Bill Link to comment Share on other sites More sharing options...

Thanks, Bill I had the same question, and there's certainly more visual or technical way to determine the tank capacity. I simply ran the truck almost empty than filled it up.

mat in tn Posted March 11 Share Posted March 11 I had the same question, and there's certainly more visual or technical way to determine the tank capacity. I simply ran the truck almost empty than filled it up. typically, they are 19 long and 14/15 gallon on short beds. I cannot say that they never put short tanks in long beds but why would they.
