I did an engine swap from FI to carb and use a mechanical fuel pump now. I would like to replace my fuel sending unit assembly with one that doesn't have a fuel pump on it. Does a direct fit replacement exist?

 

Sorry to hear you ditched the EFI.
Yes, just order a sending unit for a older carbed car.

 

You're sorry that I built a type of engine that I find beautiful and get immense amounts of joy out of?

That's kind of mean of you.

Anyway, by "from an older carbed car" do you mean an older third gen? I thought even the earliest carbed third gens used electric fuel pumps. What year range third gens should I be looking at?

 

cant you just remove the pump and use the stock sender?

 

I'm not mean, honest is a better word.
Just sorry your giving up on one of the things that make these cars a joy to drive..
I've seen soooo many of these cars with a carb slaped on them, wires hacked out and then sold because it doesn't run right. Mostly because they are no longer "fun" due to the tempermental nature and tuning needs of a carb. Even most of the people that say "I'm just going to drive it on nice days" will quit driving them because it becomes a pain. Yes carbs can work but most won't spend the time.

Yes, a older third gen that came with a carb. 82-84 an even some 85-87s.

 

You're right, my taste and opinions are incorrect. Thank you for correcting them for me. I now love EFI. Next time I build a hot rod engine I'll put boatloads of turbos and computers in it now that I like that sort of thing.

Thanks for the info in the last sentence.

 

Good luck buying a new carb sending unit as they are not made. Your only option is to remove the pump from the stock EFI sending unit and installing some kind of pickup on it. Or find a used unit someone took out to convert to EFI.

 

Glad I had the chance to change the world for the better today!
Understand that I have just seen waaay 2many of these cars beyond screwed up.
Like I said, carbs can work just fine. Most people these days want more than a carb can deliver.
I'm not here to tell you what to do or build, (thats Obamas job) it's your car and you can do whatever you want to do to it.

 

The '88 fuel sender doesn't care what kind of pump in in the tank, the signal is sent directly to the instrument panel, not the ECM if you've removed the ECM the pump isn't going to work anyway. I'm assuming you already have an external fuel pump, if not us one from an '86. I was out picking parts and found 2 carb'd 3rd gens.

 

This would seem to be the easiest solution, simply remove the pump and extend the tube down closer to the bottom of the tank.

 

This is what I did, but I've always had a nagging feeling that it's somehow not "good enough".

 

All GM fuel level sending unit resistance from 1965 to present is 90 ohms. whether you have a carb, and install an EFI level sender, or vice versa the fuel gauge will read correctly.
When the sender in my carb'd '86 Silverado craps out which it will soon, I'll replace it with one of these. They are 90 ohms so you don't have to worry about the level being wrong.

I'm thinking the OP is more worried about the pickup tube/sock than the gas gauge sending unit. (maybe I'm wrong?)
When you remove the EFI pump, the hard line needs to be extended so the sock can contact the tanks floor and pickup fuel correctly.

 

That's exactly it. I don't even have a sock on atm, just a metal line to replace the pump.

 

You're not wrong, you're a psychic, because there's not one mention of filter, or sock in the title, or in any of the replies.
No reason one couldn't adapt a stock sock filter to the end of the extended hose/tube.

 

Naw, not a psychic, just part of knowing these cars and what mods need done when things get changed.
How was the tube extended? soldered on? or hose clamps and rubber submersible fuel hose for the connection?
If the connection isnt good you can get air in the lines and it could cause weird problems. Also It wont pickup all the fuel it should out of the tank with a bad connection or without a sock. The sock also stops larger debris from getting to the filter.

 

Dang, had a response typed but it got wiped out..

Naw, not psychic, just from working on these cars for many, many years and knowing what mods need done when certain changes are made.

How was the tube extended? soldered on? clamps and submersible fuel line?? Compression fittings? Air leaks can cause weird problems sometimes.
A sock is needed to help wick the fuel off the tanks floor when low on fuel and 2 help keep large debris out.

 

not ALL gm sending units 1965 to present are 0-90 ohms. the ones in the LS1 cars are different for starters. i pulled one out of a truck to try to use for the fuel tank swap and it wasn't the 0-90 either.

 

I know you may not get to read this, but I have a carbed 1985 Camaro that I LOVE. And I put a new carb on it (Elderbrock, which meant I had to add the fuel filter to the line. No big deal. has been running great with it too without all the hitches the original carb had!) AND YES YOU CAN STILL GET THE SENDING UNIT FOR THIS CAR! You just have to look for it! More are being restored today, so more are being made. In the US they cost about 150 for one. Hope you got one, and still enjoy your cool ride. I have been driving mine around for 25 years and just finished restoring it (and yes, some women like me DO restore cars) So, good luck and I hope you still have your ride too! Cheers from Canada.!
