Holley 2300 EFI?


However, you should be able to just use a piece of hose in place of the in-tank pump on the sender assembly as long as you have a good frame-mounted pump.

In theory.

The sock clips onto the pump so you lose that unless you figured something else out there.

Actually when the first in tank pump died I ran a holley inline pump and it was content sucking fuel thru the non-working in tank pump lol.

At the end of the day the in tank pump pushing fuel out of the bottom of the tank does work the best.

When I was messing with mine nobody was making just the sender.

That is why I killed two birds and just went with the 85-88 EFI low pressure pump in the fuel tank.

This right? Just the sender and no pump.
Edit iirc the impedance was different on the newer sending units, so ill have to do more research as far as running just the sending units to a inline pump. I want to do the efi and fix my fuel system and stock fuel guage while im at it.
 
Resistance of the sending unit only affects the gauge reading in the dash. It has nothing to do with the pump.

That looks like the hanger with no pump as in pump sold separately. Its hard to tell with just the one pic though.

The stock hanger didn't have wires going down to power a pump and didn't have a return.

That's where I was with that picture. That's why I didn't mention installing a piece of hose to replace the missing pump.

I want my stock fuel guage to work… so I wanna make sure I’m getting the right sending unit I forgot which years it was but one of them has a different resistance value

The EFI kit will come with a inline pump so powering a intank pump shouldnt be nessacary for my application. Like i said i just want stock fuel guage on the dash to function again whilst i redo the fuel system.
Im going to do it different from your setup, the sending unit just for fuel guage but the pump will be inline. I just noticed that sender i sent has a return line like you mentioned so no need to drill any holes when i get the new fuel tank

What is your part number?

It looks like the part you put a fuel pump onto not really just a normal carb pickup.

The return terminates with the red rubber duckbill valve. The bracket is there for the pump to sit in. Wiring is there to power the pump.

Here is mine, take the pump out (the red and black thing) and what is left is what you have pictured.

Which would work but you need to build something to actually suck fuel closer to the bottom of the tank.

83-88 had the same resistance value, it changed for 89 (and so did the shape of the fuel tanks)

Gotcha , long tube is return, i can just extend the pickup , not a big deal. Just wanted to verify fitment, granted i can certainly do your method but i dont want to bother messing with the tank or bed in a event of a pump failure. Ill just set it up how it already is except its going to be those AN fittings.

And honestly ill probably go with the aces efi instead, my only concern is the AI customer support 🤣
