Out of order with the switch open windings

Installed on my cabin cruiser Chris-craft. He died just a few hours later. I took it off and as the 12vdc motor would not start I mounted it on my lathe and cut the crimp to take it apart and inspect the motor. After removing the rotor and checking the windings with an ohmmeter, I found two open circuits creating a dead zone such that if the motor stopped there it would never start again. It was also found that the rotor was significantly offset from the gap leading to the vane pump. Poorโ€ฆ

Pros
  • Stylish and modern design
Cons
  • Almost everything is fine

Direct replacement for 2003 Supra 22SSV

I used this pump on my 2003 Supra 22SSV wakeboard boat. Identical to the original pump. Apparently these boats don't use a filter before the pump. It turned out that the original pump's inlet strainer was almost completely clogged. I could hardly breathe air through. I plan on changing the entire fuel line and putting in a filter. I could not distinguish this model from P4594. I called Carter and a very knowledgeable representative said the P4594 comes with barbed fittings, has a slightly lower

Pros
  • Ideal for outdoor activities
Cons
  • There are other interesting options.

Hello Carter! - Electric fuel pumps

What the heck happened to Carter? This thing that pumps gas is the only happiness this thing has given me. The electronics are complete junk. I had to get inside the rubber fittings and bend them slightly to get satisfactory contact. Even then I had to build a support that would put pressure on them or they would just fall off. Second, three complete disassemblies of the unit were required to fix the leak on the pump discharge side. Even now, I'm not sure the whole damn thing won't split inโ€ฆ

Pros
  • Sturdy construction
Cons
  • I'll add later

Disappointing quality.

I went through 3 of these and none of them held up to the pressure advertised. Number 1 was 7.5psi which flooded my Edelbrock carburetor. The numbers 2 and 3 equal 3 psi. I couldn't tell if my bad problems were due to the carburetor or fuel pressure. The volume seems adequate even at 3psi, but caused a lot of heartbreak. Also, wire connectors are the cheapest things I've ever seen. Not only is there no indication of which end is the positive (which is very important as the pump will reverseโ€ฆ

Pros
  • Easy setup
Cons
  • Speed

Corrosion of the clamps, failure of the latch

The pump works perfectly, the clamps supplied do not tin and do not corrode in a few months. The case is not rusty so I don't know why this happened. Carter told me to just order new cables. Additional issues New cables arrived and I installed them with the included holder which didn't work. When the holder is installed, the wires are not connected. If you wiggle the connection it makes contact and the pump works fine, then the connection is lost and you have to wiggle the wires again. Allโ€ฆ

Pros
  • The best in its niche
Cons
  • Reliability
