Hi Wes,
yep same setup as in the first pic, just has a filter before the lift pump not after
ive got the same lift pump just one of those sqaure facet style ones.
by glow in the dark i just meant it was red hot, funny though it didnt blow the fuse although it is a 30amp
i hooked it to the battery charger and it was only pulling 2amps which was what it normally did but no signs of life
one of the first things i checked was the temp of the surge tank and it was warm but not hot, and was bubbling and gurgling away
im just impressed that i was able to get from one side of town to the other in peak hour with no lift pump and only half a tank of fuel
i'm just gonna go grab another pump same style, as its going for an engineers cert on thurs

Fuel starts bubbing at a low temp, it doesn't have to get very hot. Warm is hot enough for fuel to start to have issues.
Glowing red is very weird, lucky it didn't set anything on fire!
The facet pump is a weird pulsating electromagnet of sorts. When mine stopped I pulled it apart. The older square ones can have the inlet and outlets
pulled off. From there I think there was a circlip of something and eventually I got the moving middle bit out. I cleaned off the rust scales, put it
back together and it was fine. They now have a new model with a moulded plastic body that I don't think can be pulled apart at all.
This is like my pump (cube style);
This is my filter, rebuildable;
new plastic body one that supercheap sells (they call it the facet posi-flo pump);
They both need the filter before hand, (74 micron apparently);

cheers for all the info Wes
it wasnt physically glowing it was just really bloody hot
pulled the covers off this arvo but its fairly sealed up inside
its the same facet cube style one in the first pic
i bought a new one this arvo but a 4.5-6psi one this time and a new metal filter to go in front of it
chucked them in and went for a spin
all was fine, EFI pump was back to sounding like it was
bout 10 mins later though i started getting intermittent misfires
if i really nail it it seems to drop a cylinder and is abit down on power
lift pumps still running fine and its idling happy as larry and revs up fine with no load so im wondering if the EFI pump is down on pressure now
after running like it did yesterday
will have a mess around with it tomoro arv
this is my old one thats just died

VL Turbo, camira fuel pump, same thing you may have got a dud.
my rockets been going for about 7,000Ks now.
no surge tank on super or the 70 bug that rose raced around Wakefield park   
its just more shit that could go wrong.

its a new genuine bosch one, i think ive probably just hurt it by driving for 20 mins with the thing cavitating abit
after all this crap im thinking of just modding my tank to take an intank pump
there was an super tank already set up for one on ebay the other week that only sold for about $7
i missed it cos i was at warwick but ill probably just mod my spare tank in the same manner

Hi Joel
I'm surprised you got any flow through the dead Facet, Ive used them before and was able to turn it off to stop flow as a anti theft device.
Did that tank on Ebay have the swirl pot inside? The factory EFI tanks are available in the states.

i doubt very much that it would have
if it was out of the bug i think it was then it was a rough as guts engine conversion (ej22) and id be abit suss on the welding
but ill take the idea and try and make a neater job of it
im hoping i could get away with no internal baffles

Hi Joel
The problem with a super is that there is nowhere to make a deep pocket for the swirl pot under the tank.

If I make a new tank I would definitely put the swirl tank and pump in the tank.
To pull the facet pump apart you don't pull the body apart, you just take the inlet and outlet fittings. Then you will see the internal moving part
and a circlip or something that lets you pull the internals out through the inlet/outlet holes.
Steve, the facet didn't flow when it died. The fuel just flowed down his surge to main tank return line.

I would head to a wrecker's and check out some top mounted in tank fuel pumps, the 2005 Toyota corolla has one with about six screws that hold it in
type.

do most of those intank pumps setups mostly all use the same mounting bracket for the pump itself??
just finding one thats nice and shallow to fit a super tank will be the fun part
alot of mainstreamer intank pumps also have the fuel gauge float attached as well which makes it even harder to find one suitable
altho im sure that can just be cut off

ok well its all good
im thinking my EJ is adapting abit of VW temprament
today all is fine and dandy, its done 3 trips this arvo and not a single hickup
the only thing i did first was connected the check connectors and turned the ignition on so the fuel pumps pulsed just to make sure there was a nice
healthy flow from the surge tank back into the main tank which there was
maybe that fixed it who knows
not likely but im guessing maybe an airlock in a fuel line abit somewhere or something stupid
oh i also found something else out when testing driving it today kinda by accident
140km/h + 3rd gear = Rev limiter

One day at eastern creek on a track day my fuel system started mucking up....like it was not breathing. I was actuall running 2 x vl pumps....one as
the pre pump and one as the main pump.That way I never worried about hot fuel as the surge tank was always pumping huge amounts back to the tank from
the overflow return line....anyway after spending half the day in the pits checking everthing...I got about 6 laps with out fuel starve. Shitty.
Turned out to be a faulty pressure regulator on the late model manifold I had just purchased off ebay.
