I did an AAZ swap into my syncro passat.
I have a Giles IP and I'm looking for a lift pump (not in tank). I removed the in tank pump, because it is the only pump the G60 used and the pressure would have been too high. What do you guys recommend?
Also, what's out there for injector nozzle upgrades?

The one pump for the gm 6.5L is perfectly suited according to Giles. Rated for diesel and fairly low psi with good flow. Holley black is the only one I have heard guys running around here on diesels and it accually holding up. I am sure there are more as well. Holley black is $$$

I left my high pressure pump in the tank and just used a holley pressure regulator to reduce the pressure down to 4 or 5 psi. In my opinion this was the easiest way to reduce the pressure down to a reasonable level and keep everything in place. I've had no issues with it(2+ yrs now). I think my in tank pump outputs around the 40 psi and the regulator reduces it nicely. Regulator is only, if I remember correctly about $43.

you really dont need to upgrade your injector nozzles, these are NOT a TDI engine.. the nozzles in your engine right now are capable of flowing enough fuel to cut your pistons in half..
as for a lift pump, i had a low pressure in-tank pump in my mk2, but it kept giving me issues, so i took it out and went with a napa auto parts universal solenoid style fuel pump. its rated for gas, but ive been running it for years now, in 3 different cars, and the only issue ive had with it, was from having debris get in it from a dirty tank..

I picked up a Mr. Gasket diesel pump on the weekend. Gonna put it where the fuel filter was (or fuel pump on vr6/16v).

An awesome pump I have used on my old f250 is made by carrier. You can mount it in the engine bay or towards the tank and its a constant duty diesel pump that has no issue priming. Its low pressure as well. I have read that it doesn't like cocktails though.

I'd like to put it in the engine bay, but the instructions mention that it should go close to and below the tank.

The type of pumps that are most often used in automotive applications are better pushers than they are pullers.

Mine cost me $80 shipped from a guy on another forum that buys them in bulk. Then about $10 in barbed fittings and sealant.
You can mount it anywhere, and its better in the engine bay because it has a see through plastic cover over an internal screen that you can see the fuel level. Its also beefier than that little mr.gasket pump.
I have them hard mounted with big rubber washers in the engine bay, through a fused relay and all has been well. Also know a ton of real world examples when it comes to the old f250s and using them.
If anybody wants I can take a picture of my unit.

Giles said to me that the AAZ's OEM injectors are fine for whatever you can throw at it.
I had him clean & test/set my originals. I had planned on the Bosio injectors available from Kerma for the AAZ, Giles assured me they were overkill.

theres no way i would regulate 50 (digi) or 100 (cis) psi with a simple regulator.. is it made for such high pressure?
i deleted both pumps on my mk2, and installed a GM 6.5TD lift pump under the car where the high pressure pump once lived..
yes, i took the in tank pump out, and made a pump delete out of a piece of TYGON tubing..
