PLEASE BE AWARE THERE MAY BE SOME DELAYS IN SHIPPING THIS. DENSO HAS DISCONTINUED THESE, so all that is left is whatever some parts houses have on the shelf

Genuine Denso fuel pump same. Comparable to part No. 23221-46110

We purchase these fuel pumps in large bulk for our fuel systems. What does this mean for you? Well we can offer just the pumps to you at a great deal!

Over the years, there was a switch to the Walbro 255 liter per hour fuel pump as a replacement when upgrading the in tank fuel system on MkIV Supras. This trend increased when people starting going to dual and triple pumps in the tank, as the Walbros were thought to flow more than the factory Denso units and were smaller in diameter, which facilitated multiple in tank pumps rather nicely.

As time developed, it was learned that the original testing done on the Walbro 255 vs. the Denso Supra pump used a flawed methodology. The actual results show the Denso flowing at nearly 290 liters per hour at 43psi and as much as 225 liters per hour at 58psi.

The 255 Walbro flows about 250 liters per hour at 43psi, or approximately 15% less. The Walbros are still a very good pump, but not up to the same quality level as the Denso units. It should also be noted that the Walbro-Whine (noise from the pumps when running) became synonymous with multi pump set-ups.

The Denso units are factory quiet as well. Just another option and some data from SupraStore.com

These are the same fuel pumps from a USDM 93-98 Toyota Supra Twin Turbo, that have been used in many other high HP imports for years.

These are the Denso pumps used from the factory. They do not come in the Toyota box, though if you wish to pay more for the Toyota box, we can arrange that!
