I took 2 pics to be safe, i currently have a fuel pump assembly named TRQ in my 94z28 camaro m6, my old fuel pump which was an OEM with the sending unit/floater like this, but the TRQ one has a different floater, my camaro runs n drives nice, but my fuel gauge/ needle jumps/ tweaks way past F when i floor it, when i stop its goes between 3/4 and F, but idk if with this TRQ fuel pump is good, so i went on ebay n got this one from a 112k mileage 95z. Will this be ok for my 94? Thank you guys
The OEM pump in my 94 had a white plastic bucket enclosing the pump. The “bucket” is important to keep in the pump from pumping bubbles, and keep the pump cool. Seems to be missing on the used pump. Read what Racetronix recommends in the “APPLICATION SPECIFIC FEATURES”:
If the float assembly is a problem on the new pump, swap it with the float assembly from the old pump, and install the new pump. There may not be anything wrong with the new float. When you apply the brakes the fuel flows forward in the tank’s triangular shape and the level rises. When you accelerate the fuel flows backward in the tank, and the float drops.

Oh my gosh thank you Fred, because that's what I noticed about this pump I'm like where's that plastic cover, I haven't installed it yet, but my concern is I just want to make sure my fuel gauge is at the right mark, but I am thinking to swap the floater with the oem (yellow one), but is that hard to do? I'm hoping I don't break anything, if I swap floaters, do I need to do any other swapping like wires etc. Thank you again man
As I recall, the float assembly is attached to the sending unit frame by rivets. I had my engine built in 2000. The fuel tank was pulled to add a sump to the tank to add a second, external pump to supply fuel for the nitrous. When I got the finished car back, the fuel gauge was no working, and the line from the sending unit to the EVAP canister had come loose, resulting in fuel smell at back of car.
Returned to the shop, they tried to order a new float assembly, but back then the only way to get a new float assembly was to buy the whole sending unit (without pump). They drilled the rivets out and swapped the float assembly from the new sending unit to my stock sending frame (the stock in-tank pump had been replaced earlier with a Bosch high pressure pump). I assume they either pop-riveted the float assembly, or used small bolts.
They gave me the left over new sending unit, and I had it in the garage for 20 years. I gave it to the guy who bought my Formula, along with some other spare parts. The above photo is from him, and I suspect it might have been my old frame. The wires are connected with little push in spade connectors. Should be an easy swap.
