Review on TERAPUMP 4th Gen - Fuel Transfer Pump | No More Lifting Gas Cans | Fits Multiple Gas Cans (Advanced Auto-Stop Sensor & Flexible Inlet/Outlet Hose) by Viswanath Badasz

Update 7/7/2020: My attempt to seal the fuel pump wiring hose and the wiring connection to the ECU failed. The leak isn't where I thought it was and if there was one then Seal All stopped that leak and found another one. Most likely the leak wasn't where I thought it was. I removed half of the battery box from the controller case and started the pump. The leak was not inside the controller housing, it was leaking out of the lid and bypassing the lid's rubber gasket. The only thing I can do is that there is a crack or other leak path in the plastic knee that is part of the bottom half of the controller case. There is no visible damage, the path of the leak is unclear. I'm going to install a fuel line hose from the pump to the injector and I'll just tie the controller to the fuel line and you're done. I'm going to route the wires on the outside of the fuel line and pierce the fuel line next to the pump to get it inside. I will use Seal All to seal the hole where I insert the wires through the fuel line. It will be a complete hack but it should work. I bought this thing late last summer and only used it once. It worked once without a leak. It stood empty for 10 months and was stored in a barn during the winter. I don't know if the cold did him any harm. I can't imagine what happened as it was completely empty. Anyway it's too late to return it and I need it to work so I'll make it work and I don't care if I can use it as a gas cap. Original review 05/07/2020: I would have given this review 5 stars if it hadn't leaked like crazy. The pump itself works great. The weakness is that the pump motor wiring runs inside the fuel pump tube. The pump wiring is housed in a small plastic tube that inserts into the tube flange slot on the control box. The fuel pump tube slides over a slotted flange where the pump cables run. A plastic ring is pressed around the fuel pipe, sealing the fuel pipe against the pipe flange and the line pipe in the slot. The problem is that the slotted conduit creates a leak path if it moves even slightly in the slot. The plastic ring that holds the fuel hose to the control box is easy to pry off with a screwdriver and the hose is easy to remove from the flange. I'll try to seal the wire slot and fuel line with Seal All. Hope this stops the leak. In my opinion the manufacturer should have wired the pump from the controller outside of the fuel pump hose instead of inside and placed the cable entry point at the end of the fuel hose on the pump side instead of the controller. the end. It doesn't matter if the wiring at the end of the pump causes a fuel leak because the leak will be located inside the canister and no one will notice. However, by inserting the pump leads into the fuel hose on the ECU side, the leak path bypasses the cap's rubber grommet, goes through the cap's threads, and then all the way around the outside of the fuel tank. The fact is that the leak practically does not affect the pumping volume. Works great even when leaking. If the leak had been located entirely in a fuel can, no one would have noticed. However, due to a fuel leak at the end of the controller, this creates a major mess. Even if Seal All stops the leak, I won't give it more stars because I don't have to fix this design flaw.
