Denso, or Bosch if you want something that isnt cheap and going to die in a couple years. Or a new skyline, Z32TT pump ? Havent done much research on those but i'd bet them to outlast walbro by at least 2:1
not tryin to argue, but I've had a brand new denso die in 8 months and I went through 4 bosch pumps in less than 6 months.
There is good and bad with all of them. Which I guess is true with just about anything.
I've personally always been impressed with Walboro pumps. I've put 30k plus miles on the one I had and the other cars that I've put them in have always lasted a considerable amount of time.
A TT pump would be way over kill since they flow like twice what a walboro does. an NA one should be more than enough. But don't quote me on that. I just know that when you do the TT swap in the 300zx's, if you use a walboro, you have to use two of them to keep up.
There is some funny wiring thing that you need to look into with the TT pump. It is my understanding that there is basically a low speed and a high speed.
But it would last a substantial amount of time. And you wouldn't ever have to worry about having enough fuel.
OP, if it has sat that long, then yeah, the pump is bad because of just sitting in that ethanol gas. Could have torn up the fuel pressure reg too.
What did you do to keep the water out of the tank? Ethanol absorbs and holds water, so it could the fuel could have just been watered down and that could be causing the problem, or maybe even what caused the damage. Just things to consider.
