Tomei Hcr32 Fuel Pump

[B0oStEr]

I bought a used 3000km old Tomei fuel pump for my r32gtst.

Looking at the Tomei site it appears to be the correct one, part no. 183001 but this part no. isn't on the pump.

I was a bit surprised to see the Nissan emblem on it even though I didn't really expect to see Tomei on it.

It's marked Unisia Jecs A42-621B70

I found a pic of a bnr32/Z32 fuelpump and I can actually make out the same model no. on it.

The R32gtst Nismo pump is the same also.

It seems as though they are all the same pump so I don't care if mine actually came from Tomei or not.

My only concern is how it fits up.

The Tomei kit doesn't come with the clamp or extra regulator thingy that can be seen in the first pic but they were there in the bnr32/Z32 pics.

Are they needed for the r32gtst?

The Tomei kit comes with a spacer and cushion and I did not get these with my pump.

Do I need them for a drop in fit?

Can someone please shed some light on this?

This is an R32 GTR fuel pump.

Thanks Topaz.

i have bought a few TOMEI pumps over the years and have one in our current S13/26 and it definately came with reg/damper and all associated mounting hardware.

Another thing that puzzles me is if the tomei gtst pump is the same pump as a std gtr how come they rate the tomei gtst pump at 248L/hr and rate the std gtr pump as 195L/hr?

Maybe they just look the same.

Does anyone know the model no. from the tomei r32 gtst pump for certain?

I'm now pretty sure my pump didn't come from a tomei kit.

From the gtst nengun link in my last post it appears the tomei kit doesn't contain the regulator/damper thingy that came with the pump I bought. (Check pic in first post)

Tomei obviously don't think it's needed.

What does it do?

My pump didn't come with the cushion and spacer seen in the tomei kit.

I've ordered the cushion from Nissan as a genuine gtr part.

I think the spacer is made by tomei as a gtst adapter so I guess I'll have to make my own.

Given that all evidence points to the r32gtr pump and the tomei gtst pump being identical why are they rated differently?
