high pressure fuel pump
hi all, well I had a search but couldn't find much, I have the fuel pump for my engine that came from the car, problem is its an internal in
tank type, so its not much good at the moment as I will be running a surge tank set up..
Question is can I strip the pump of the plastic bit that surrounds it in the tank and pick up etc, and just mount externally after the surge tank..
(as a external high pressure pump)
Reason for this is that after market hp pumps are expensive, and would need a regulator to match (pump I currently have already has a regulator as
part of it) and the fuel rail is only set up for 1 line (return is on back at the regulator installed on the pump)
Engine is a 98-99 toyota beams 3sge from altezza/is200
cheers aaron

Probably not, they use the surrounding fuel to cool the pumps..

Yeah I thought about that, but in my normal car, with an internal pump I drive around with only a drop or 2 of fuel in the tank for ages - and no
problems!
Another idea is to custom mount it into the surge tank (so it would be operating as normal)

Vauxhall out of tank pumps are cheap and have easy to used 1/2" inlet and 8mm output. If you are running a swirl pot that would normally have a
return connection. The norm would be to have the regulator after the injector fuel rail with low pressure return to the swirl pot. Easy option would
be to get a £20 used Vx pump, regulator and run a return feed to the swirl pot.

I run at 3.25bar which is about 50psi..4 bar is getting near the higher side of most designs, any reason for this? perhaps you need to think of higher
flow rate injectors to bring fuel rail presure down.

62psi is just the standard pressure fuel rail pressure the for the engine with standard injectors and ecu - so that is my reasoning behind the random
number 62.. was good enough for toyota so better stick to that

Sounds reasonable!
You can get an aftermarket regulator set to whatever you want for about £50.

bosch injection pumps (which is what the vauxhall pump is) will all run in the region of 90 psi as a maximum, certainly 60 psi is no problem.
They are all cheap even new on ebay apart from the "044" ones which are the big beasts..........
guess what I needed for my twin engine installation!!! 
here's one:
bosch pump
and another:
another bosch pump
