77-78 Fuel Sending Unit

[Av8ferg]

Have you guys noticed that there are now new fuel sending units for 77-78’s available at Zcardepot? I had been looking for one for sometime when I bought my car and they were no place to be found, even used. Has anyone bought one of these. I had considered having my refurbished awhile back but is was about $200 to do that so I decided I could spend that money better elsewhere. This looks like a good but if they’re any good.

I just ordered one and will compare it to an original.  I'd be excited if my low fuel light worked with this one.

Well, I think I’ll order one too before they become unavailable again.

yeah,  they look like the original, shape wise at least, and worth the effort IMO.  I don't imagine Z Car Depot selling anything knowing it's a bad product.

It looks right.

I don't want to badmouth zcardepot.  But, no business can be assumed to be perfect.  If he found a pile of NOS parts that's great.

Looks compatible, not a Nissan part of course, their part numbers start with 200 for oem, 800 for aftermarket.  Good for Ryan to find an aftermarket one that works.   A new oem lock ring is only $5 more if you need one.

Well I received the fuel sender today and got it installed. I'm impressed with the build quality of it and there are only couple of minor differences from an OEM one.  They are the same size and length, has the correct bends, the alignment notch is correct, sweeps up quicker than before and it fits just fine. It even comes with a new gasket.  The only problem I have is that where the low fuel light never worked before, now it's on all the time, even with a full tank.  I don't think the sender is the cause just yet so I've got some exploring to do.

Good to hear...  Probably works in reverse of the contact being open or closed for the low fuel light.   When you get near empty, the light will possibly go off.

Problem solved.  A long while back I had replaced all the dash lights with LED's.  There was an LED  instead of an incandescent bulb in the fuel warning indicator and as explained by @captainobvious in another thread explaining how the fuel warning light worked here:

I figured since the LED requires a lot less energy to light up compared to an OEM bulb and with a constant draw from the warning light on the fuel sensor, it would always be "on". I changed it back to a regular incandescent bulb and now it's off with the tank full.  I'll just have to run out a full tank of gas to check that it lights up close to empty.  If it works, and I think it will, I'll have two extra 77-78 fuel senders.

Sometimes we get lucky and lightning strikes in the middle of the night with the possible solution! I'm glad it was a simple fix and all of us that have swapped to LEDs will benefit from your experience. Thanks !
