the universal SHAKER pumps you get at the auto parts stores are fine for cocktails.. there are no rubber pieces in them, just some springs, a plunger, and a couple check valves..
ive been running one in my diesel for a very long time.. its just an electric fuel pump, meant to feed a carburator, but rigged up under my Jetta, and pumping diesel..
Autozone. Com has a few different ones.. Around 4-7 psi max.. Sounds good! Is it OK to run about 5 psi @ my IP all the time?

you can run like, oh, 30 psi safely to your injection pump.. i think thats what giles and tyler fed a pump with..
be sure it has a flow rating of atleast 15 GPH.
What's the purpose of the lift pump if your IP is good? I thought you'd only want to use one if your pump isn't priming properly.

if you want power, then vacuum at the pump inlet is bad.. it makes the timing advance later than if the pump had pressurized fuel waiting for the vane pump to inhale..
basically, is it easier to suck fuel thru a 20ft drinking straw, and fuel filter? or is it easier to let the fuel simply flow out of the 20ft drinking straw, and be delivered to the pump, rather than be pulled to the pump..
you can STARVE the pump of fuel in the higher rpms, and with a lift pump, it doesnt happen. when the engine is revved up, the vane pump is making LOTS OF VACUUM, and it can aerate the fuel in the lines from vacuum. if you have a lift pump, and any amount of positive pressure, the fuel will NOT AERATE..
Well I installed a lift pump off a Chevy diesel for $8 from the junkyard.. Ooo wee couldn't be happier! Bucking is gone, multiple great effects. Shoulda done this sooner or it should have come stock!
So is there an upgrade for AAZ nozzles?
Walbro fpr is made for diesel and is biodiesel ready. I think mine ran 100usd.
theres no way i would regulate 50 (digi) or 100 (cis) psi with a simple regulator.. is it made for such high pressure?
Walbro makes a line of lift pumps perfect for our application:
http://www.walbro.com/producthlt.aspxIt's been mentioned here before, I don't think I'm the only one (planning to) run one. Mine was <100USD, but I ordered it so long ago I can't remember.
You won't need a regulator, ditch the tank pump if that's what you're talking about. It's likely to go, as all of it's rubber seals will swell with diesel (around here most/all diesel is B5 - 5% bio)
giles reccomends the 6.5TD lift pump.. there around 50 bucks new, iirc..

a 6.5 td what?gm ford? and does it just drop into the tank no modifications other than maybe different hose size?
GM 6.5, it is inline not in tank.
