gorillabear Posted July 6, 2011 Report Share Posted July 6, 2011 I recently bought one of the ones listed on ebay like this : DATSUN-520-521-620-610-710-A10-Fuel-Tank-Gauge-Unit I got it the other day and it won't fit in my tank. It's rolled at the edges and it's too tall for the lock ring to work. The seller wants me to grind them down but before I go through the trouble I wanted to see if this even looks right. To me the angles of the bar and float don't look correct but I've never had an original one. I just held it up and moved the lever and it didn't seem to register correctly on my gauge. Does this look correct for the 521? Quote Link to comment
jefe de jefes Posted July 6, 2011 Report Share Posted July 6, 2011 Looks similar Quote Link to comment
wayno Posted July 6, 2011 Report Share Posted July 6, 2011 It looks right, but it is just a photo, I was wondering about that sender, but it is the only one for sale on ebay, when it's the only game..... Quote Link to comment

burrito213 Posted July 6, 2011 Report Share Posted July 6, 2011 i think you got the same thing i did. does your original have holes and this new one doesnt?..... the one i bought: this is the one off my truck: i have a 320 but that no longer means anthing because my truck was put together like a 520.

droc71 Posted October 17, 2012 Report Share Posted October 17, 2012 did it work? im in need of a sending unit also. if i can modify a 720 an or a 620 sending unit i will go that route. Quote Link to comment
datsunaholic Posted October 17, 2012 Report Share Posted October 17, 2012 I looked at several of his auctions- the list of vehicles most of his parts "fit" are highly incorrect. The fuel sender is one that fits the 520/521 Utility, which was actually the "Double Pickup" that had a unibody bed and a tank in a different location with a different design. It actually says right on the ad it doesn't fit the truck. The fact that it fits sedans means it'd too deep for a truck underbed tank. These are for Mexican (and Central America) market vehicles that we didn't get here in the States, for the most part. Quote Link to comment

You still have a 320 gas tank though, as that is a 320 sender, and the new one looks to be for a 521 Quote Link to comment
FOG Posted June 29, 2022 Report Share Posted June 29, 2022 (edited) Have two 521 Datsun pickups needing fuel sending units. The top of the OEM units have a fuel return neck. Currently have not found a source for these. Can anyone point me in the right direction? Edited July 6, 2022 by FOG Wasn't phrased properly. Quote Link to comment
