R50 Fuel Lift Pump

Post by mudbugga »

I have heard that adding in an electric lift pump can help reduce chances of the electronic injection pump cavitating and failing.
I'm interested to find out what was done exactly before I fit in a pump I have managed to find.
Am wanting to fit an auxiliary fuel filter at the same time, so have scored a Hilux filter housing and bracket off a "shagger" Hilux that should do the trick I reckon.

Bosch 440 from a commodore should do the trick

place inline , i doubt you'd need to put in another filter, unless your like me and submerge most of your truck in mud most weekends the normal fuel filter is suffice, also the more restriction on the flow of fuel the more likely the pump is to cavitate. .

But it isn't cavitiation that causes these pumps to fail, they flow plenty for what they do bolted to the TD/QD blocks, and being ETI you cant just wind up the fuel anyway.

it's the lack of a lubricant additive in the fuel the damages the soft metal components inside the pump (needle valve seat etc) that creates wear leading to the binding of the internals...and basically being a viarable electro magnet moving a plunger the more play the faster it wears.
Waiter...there is a drought in my glass.

I have got a low pressure pump that flows 80L/hr that I was thinking of using. Reckon that'll be OK? Have been thinking it may be too restrictive.

But I might just fit the aux filter anyway without the pump for now because I can. Piece of mind more than anything else.

i suspect that pump will be to small.
also be careful with adding extra filters. extra restriction can cause issues with some injection pumps.
if you fit an extra filter fit a lift pump. at least 150L/hr and have a one way valve in parallel with it (acts as a bypass when pump is off or causing a restriction).
