So I go out today to install the Denso pump that I bought in the summer

[Just a Six?]

I have 2 Walbro's & usually in spring it reads higher & then gets better each with fill up but I still don't trust it 100%. Usually there is a least 1-2 gals more than it reads so that's better than having 1-2 less than you think & running out. I have a spare hangar here but can't be bothered to change it. Not a big issue for me since it's not driven all that much.

Pretty sure the impedance numbers can be found somewhere to test the hangers with a DOM.

resistance is 0-90 ohms on analog dash and 0-120 ohms on the digital version...

Should be able to tell if it is working, more or less, by checking from float at the bottom of its swing to the top of its movement.

I had trouble once where the gauge plugs in in the dash...cleaned up the terminals and it worked properly again

Good to know for the next time I get surge of energy, (hopefully before my 401k kicks in).

[earlbrown]

resistance is 0-90 ohms on analog dash and 0-120 ohms on the digital version...

Is that stop-to-stop? Or is it relative to the imaginary plane of the hanger's mounting flange?

[Steve Wood]

that is stop to stop....I will check the one that is out of the car at the moment tomorrow and see what I get

[Steve Wood]

If I had any sense, I would buy a new wiper resistor...dam n sure hope this one works better in the tank than it does in the air...

[earlbrown]

I've never looked before...   Can you open up the box and flip the resistor like you can in a starter solenoid?

[Steve Wood]

I tried...did not help...took it all apart and cleaned it a bit...tried to put more pressure on the wiper and such...still sucks...

Had "issues" with the Autometer gauges in the 55. Called them, was told 2ohms or less on the connections to ground.
The 55 install is new, I'm anal about this stuff, still ended up with 20+ ohms on the ground side at the tank. [Grounded to the welded in studs on the body.] Ran a dedicated ground from the tank hanger, directly to the batt.Now reads <.2ohm.
Same with the volt meter in the dash. Batt neg is cabled directly from the batt to the ft of the car, to the frame, engine and body. All with 3/8 bolts, star washers, yadda, yadda. Gauges were grounded the same way> welded 1/4" studs. 25ohms at the stud to batt neg cable. Cleaned, added No NOX grease,...WALA <.2ohms.
 
These same issues have arisen on the GN..Added grounds, checked and rechecked, cleaned. Gauges are much more accurate....
The Autometer tech made a comment I'd not thot of: The gauges are actually just volt meters, with different faces on them...
 
Back under my rock...

[Steve Wood]

yeah, I have seen companies that would convert volt meters to other gauges....

If I had not already installed the new bulkhead connector and harness in this sender I would buy a new unit, but, since Jack will not sell you the ten cent bulkhead retainer by itself and warns that you will have to buy the $40 harness again if you screw it up, I will just hope the sender will work again in the tank...

[daveismissing]

 ten cent bulkhead retainer

got a picture of this?

[Steve Wood]

yeah, but Jack does not like his stuff shown for one reason, or the other..

it is just a stamped out piece of tin that gets pressed over the back of the bulkhead fitting to retain it similar to the factory set up...with one difference, the in tank harness connector has no way to retain itself to the bulkhead connector and can easily fall off.  Therefore Jack's retainer has a leg on it with a slot on it that snaps over the in tank connector to keep it in place.

You have to be careful to install it properly because if you get it 180 out, then the connector will be 180 out and then the wires will not be properly connected...an d you have to buy a complete new harness in order to get it right-as per his comments...

Just think of a star washer with the teeth on the inside and a slotted leg sticking up from one edge of the washer

[nocooler]

Steve with all your knowledge and wisdom you still haven't learned to leave shit alone......I love it.

[Steve Wood]

nope...I am still a little kid at heart....alway s think it can be better
