My Walbro 340 is dying so I'm researching pumps now. Yes I've read all the threads on the Bosch 044/Supra-Denso pumps. :)

But has anyone tried using the Bosch 040 pump yet? If so how do you like it? It's for in-tank use so it should fit better than the Bosch 044. I think it flows slightly less than the 044 but is on par (or maybe a little better) with the Walbro 340.

FWIW my WOT fuel pressure should be 67 psi. It would only get to 60 psi and then drop to 58 psi.:eek: I'm pretty sure the only thing that saved my head gaskets was the alky....boost at 24 psi, 750 mv and 0.0 knock on the Scanmaster. Thanks Julio!!
