Can't I just send you one? I can mark it as a gift. Will they still hit you with taxes?

Was thinking I would include a pump next time I order something from the states so I'll wait till I know what else I want - but thanks for the offer.It's actually the shipping that tends to be the killer for single items like that.
We do pay tax on it here but it's my company vehicle so I get it all back anyway .

ah yes - That was an even better deal for me
I suppose it depends on who is doing the shipping - some companies must think of a number and double it ....

So, if he cut it, how is he going to install the new pump?
That ring is a $60 part and will take quite a few days to acquire.
The gasket is another $60.

The OE pump from the second-generation RX-7 Turbo-II fits as well and is dirt cheap.

well.... its not my opinion, but apparently the OEM TII pump kinda sucks. However there is a Walbro 255lph pump that seems to be all the rage. i wonder if there would be fitment issues...

Some of the Supra guys use the TII pump as an upgrade!

Trick is to find one that doesn't think the relationship is about showing interest, rather than doing interesting things.
Niki is bored to tears when I try to explain a compressor map, but she is very interested in the result!

the FSM has pressure: 375-450kPa {3.38-4.58cgf/cm2, 54.4-65.2psi}

but i dunno about flow rates..

fwiw the TII pump you mentioned does around 85psi... but that doesnt really matter.. flow is what matters....

^^ the FC pump says in the your pic of the manual (image, line 7) is "at least 1,3 liter/minute" .... so it should be 78 liters/hour, correct ??

what's the rx8 OEM fuel pump flow ??
