DARIN 510 Posted January 4, 2022 Report Share Posted January 4, 2022 So I know for starters aftermarket units exist but who wants crappy Chinese made shit when you can use a factory Nissan part. Am I right ? 🤣🤷🏻♂️ So I have seen only a couple people attempt to do this so I thought I would make one article a little more in depth. parts list S30 fuel sending unit 25060-E4100 O-ring gasket 17342-18000 Lock ring 17343-14801different bend from the 510I straightened the rod and put a bend in the correct placeBent new 90 degree to specHammered a flat tab like factory to retain the float. Just grab the flat tab and twist off clean Quote Link to comment
KELMO Posted January 4, 2022 Report Share Posted January 4, 2022 From the look of the larger white tag on the parts, that indicates still available through your local Nissan dealer. The lock ring and O-ring should fit virtually any Datsun of the '70s era. Quote Link to comment
yenpit Posted January 5, 2022 Report Share Posted January 5, 2022 Always thought that would work!! Nice!! Are there two terminals on the 240Z? If so, one is a ground, whereas the 510 must simply ground thru the unit! Quote Link to comment
KELMO Posted January 5, 2022 Report Share Posted January 5, 2022 I think the 510 Wagon has 2 terminals. About 95% sure on that. Quote Link to comment
Goemon Posted January 6, 2022 Report Share Posted January 6, 2022 I cleaned, zinc plated & rebuilt my 79. A 720 is perfect for 620, there are just different harness connectors. It went into a 720 tank since they fit 78-79 620 Quote Link to comment
DARIN 510 Posted April 20, 2022 Author Report Share Posted April 20, 2022 So I finally got around to doing the install. I got lucky with the gas level. Quote Link to comment
DARIN 510 Posted April 20, 2022 Author Report Share Posted April 20, 2022 This is what was reading before the install. After install the needle jumped to the line on E. I filled the tank the next day ($60 later ) going to monitor how it reads as it goes down and report back. Quote Link to comment
