Ok this is the second one that has felled At $7.00 is cheap but the last one cost $200 Tow home from the track. Just oiled down the staging lane.what should I do to stop this madness?
-
either install a mechanical gauge or buy a different brand
-
Where are you getting a $7 sender? The wrecking yard? I got an acdelco(probably a knock off) off the eBay and I'm pretty sure I paid more than that. I run a brass street tee with the stock sender and the gauge tubing.
-
I have a mechanical gauge
But in Hawaii I have one choice and Napa dose not stock and $20 shipping for there’s
I’d like to take it out and hook the two wires to the fuel pump relay together
-
why do you want to hook the wires together?

Is the fuel pump relay good?
-
My fuel relay is good ,but It provides backup for fuel pump if the relay fails, correct
-
Ok I have reviewed the wiring diagram for the 3ed time
I don’t need it at all. Correct
-
It does provide a back up circuit if the relay goes bad. I have not had one on either of my two buicks in the last 20 years, or more. I think I replaced the relay just for the heck of it a few years back on both cars as a precaution.
-
Carry an extra relay in the glove box.
-
And relocate it so I can get to it
-
Where is yours? I believe it is on the pass inner fender beside some other things. Maybe I've forgotten.
-
While you are at it, Tim, convert all the relays to standard relays so we only need one spare :D
-
I have recently been burned by some really sh*tty aftermarket relays, tabs coming off etc.
-
the ones in a box from GM have a smaller box inside that says made in China. I suspect you can find some quality units from Germany, or elsewhere
-
My stuff from Summit came in and I have done a few mock-up.
But you have my attention on converting relays to modern relays,is there a thread on this I missed or a write up in Vortex?
-
No, I would have thought John Spina would have done it by now.
Should not be hard to do...just have to take a new relay socket and look at the wiring diagrams and connect the wires accordingly.
-
Car makers have moved to newer form factors, are you suggesting those Steve?
I like the Panasonic CB1-M-12V as a traditional relay, potted bottom.
If it says Panasonic, potter brumfield, schrack(TE), Omron its not junk.
Still searching for my ideal sealed socket.
All this is probably worth a discussion of its own
-
No, Dave. I don't have any problem with that either, for that matter.
I am suggesting to use standard relays that can fit more than one circuit. GM relays, in our cars, have a multitude of pin locations so one cannot expect to pull a fan relay and have it work in the AC location or fuel pump slot.
Of course, I may be nuts or dreaming and they will all interchange LOL Or, maybe they just built me unique cars??
-
Here is my fix 12-24 screw with a.040 hole screwed in this should keep the leak to a small stream if it fails a third time
-
Also got this cool manifold
-
You musta been a plumber in your last life! :)
-
Thanks for the nice words.I did what everyone has done in the past and added a T on the engine stand.Not so easy to get to in the car.
This will be the third switch,cold start is 60 psi with 10-30 or 40 W.I have TA oil pressure adj ,I don’t watch the oil pressure like I should probably but never see it higher than that,hot idle is less than 20 greater than 15.
-
No load on the parts at idle so 15 is more than enough
-
I have always been happy with idle oil pressure and 60 looked like a good number too, I don’t see any post where people have the sending unit feel.
-
I was going to say none of mine have ever failed, but it dawned on me that it's been years since I had one installed. I suspect the problem is simply poor manufacturing-at least on replacement units.
These days, I often would rather have a junk yard part than a new or rebuilt part....especi ally the rebuilt junk.
