i have heard that this is a good upgrade. does anyone have any experience with this?

andy2 has one... he also said that when calibrating a pump on a test bench they hook the pump up to a 5 psi lift pump... would help quite a bit imo... but good ones are quite expensive

I installed one on my Toyota Diesel, not sure if it helped or not but sure didnt hurt. I just used on of those cheepo pumps from Checker (US) that was under $20 and rated at 3-6 psi and 90+ Ltr pr hr.
I'm planning on doing the same thing as soon as I acn get the Jetta fired up and running.
Sure makes fuel filter replacment cake.

any other input?

I have one I have to put on yet but it is 3-6psi and 50gph or something like that, I plan to use it if/when I change injectors to prime the pump back up so it starts almost immediately (did this on my dad's jetta) and also to use it when I install my vegie tank to help the pump.

Giles recommends using one. You can find gasser carb engine pumps for cheap.

performance wise there is any benefits?

Master ACiD · « **Reply #7 on:** January 18, 2007, 05:58:47 pm »

ive got one on my diesel. my dad said my engine is the smoothest running and most powerfull non turbo 1.6 hes ever seen, and hes owned plenty of them, even bought a brand new rabbit once off the showroom floor.
dont know if thats the electric pumps doing or not but i figure it cant hurt.
my pump came with my car which was originally a fuel injected gasser converted to a carburettor, so my lift pump is a low psi unit designed for a carb. came on the car when i got it.

i would go as far as saying that it would increase the lifespan of your pump... even though it should already be high...

the theory behind the lift pump, is that it will give you a smoother idle, and more power way up in the rpm range by delivering much needed fuel with no air bubbles. on both my diesels when i rev the engine and watch the fuel line, i see a surge of bubbles. not big mind you, but enough to hinder performance.

FWIW:
I can supply 12v - 4.5 psi solid state pumps for around 50 USD shipped in the us.. These have no moving parts, and are practically indestructible.. I can get Canadian shipping prices if people are interested.. If enough folks up north were interested and I could find a partner, I could ship a whole bunch up and have that person distribute them..

Just a thought.

No moving parts? Pardon the ignorance, but how does that work?

Not sure exactly, Never ripped one down.. but they are damn good.. I might be wrong about no moving parts... definitely no electronic motor though..

Here's the datasheet

Here's a pic if interested:

yea i'm interested in that pump. sounds just what i need! no moving parts!!!! indestructible... even better!!!! :twisted:

i'm just throwing this out there, but would it work like a subwoofer/vacuum pump to create the pressure using a diaphram??? so it uses magnetic power to create the pressure and a check valve not much unlike a vacuum pump... sounds good to me

I really don't think it has any diaphragms either.. I'm ashamed to say I really have no clue how they work.. I know they are beefy though, I've used one for years for all sorts of fluid transfer, never misses a beat.

Sounds like a nice pump to try... I wonder how it'd hold up to biodiesel. Bio likes to eat anything made from natural rubber (although not viton or most plastics).

As far as installing, I guess you could simply put it on a separated keyed power circuit with an inline fuse... Hmmm.. Would you mount it back by the tank or up front to "pull" the fuel into the IP?
