Lift pump for Puma Tdci

**newhue** · 8th February 2013, 09:21 AM

I'm in the process of potentially fitting an electric pump close to the standard fuel tank to eliminate bleeding issues. More for filter changes than running out of fuel.

The LR process of fitting the hand pump to the motor when required to prime if not my liking. It has been suggested to me to fit a hand pump in inline instead of the electric pump. This would be after the tank, but before the fuel/water filter. I'm not opposed to this as it is simple, but ease of access for use can be a issue.

I currently have a Hansa 3 to 7lt per min fitted to Mulgo's sill tanks, the standard fitment to transfer and re-fill the main tank. It's is primed all the time and has very little lifting to do.

I assume a second Hansa pump would have enough lift to service the main tank. I want to use the same pump for ease of spares and redundancy.
Can anyone clarify if there is a difference between a lift pump and normal pump.

The standard fuel delivery on a Tdci is via vacuum to the pump in the engine bay. So 3 to 7 lt per min would be about right me thinks, with the excess simply returning to the main via the standard system. I do acknowledge however, if my lift pump fails, then a the car will stop.

Can anyone add comet + or - on this. Am I over working this.

G'day Newhue, I replaced my whole filter assembly with an after market one with built in hand primer (similar to HZJ toyota style). Works a treat. just have to modify the protection cover to make it fit, which I havn't done yet (after about 3 years with no damage). Also replaced all fuel lines with rubber and ditched the fuel cooler/warmer as the coolant lines got ripped off first time I went bush.

After approx 30 000km all good

I have a Chev V8 Diesel lift pump on my T5d to transfer fuel from aux tank to main, I dare say it would be ideal for your purpose.

Hey gerokent,
Was that second hand or new. If new can you supply a link or model number please.

I have also been looking at a water trap and a water detection pickup that has been bandied around the forum. Of course here in Aus it's way over prised, and a US supplier wants crazy freight for its size and weight. Maybe a new system is easier. I'd still have to modify the standard mount if I went my way anyway.

Newhue, The filter assembly is a "Fuel Manager" brand, 100 series. I brought it from a fuel injection repair place in Kalgoorlie, though I would presume they are quite common.

3 to 7 litres per min could be too low for what is needed. I don't know what the requirements for the puma are, but I doubt you will get anything like 7 litres under load, maybe less than 3 even.

Don't go by the engine fuel consumption for the required flow rate as the HP pump will circulate a lot more than that under full load.

Edit: The Air Dog system for my Isuzu put out 6.3 litre per min at 12 psi, but the Isuzu requirements aren't as high as I suspect the Puma would have.

The TDCi fuel filter is manufactured by Stanadyne, and is from their FM10 range, which according to their website flow 230l/hr.

thanks I think you guys are right, my pump isn't going to cut it. The real down side to what I am proposing, is if the lift pump fails for what ever reason and I run the engine's fuel pump dry, I have most likely given it the kiss of death. Well most likely over the next few months from what I have been told.

maybe the inline hand pump like for an out board will suffice. Providing it lets the flow through it does nothing until required. Maybe just pull a part the "special tool" and mount it premaritally. Sounds cheap and reliable.

Sorry but it sounds to me like your creating a solution to a problem that isn't there.I've run every vehicle I've ever owned dry and have yet to have an issue,the TDCi doesn't run ''dry'',it miss fires and coughs to let you know it's run out,if you turn the engine off when it starts misfiring you only have to refuel it and drive away,no other work needed.I know this for a fact because I've done it twice with mine.

yes like pat says, you get enough warning to shut it down, if you continue to crank and crank (why would you?) then it will just take longer to restart as you have emptied the system more. i had a problem recently with a fuel leak emptying the pump and fuel lines, just filled the filter with diesel, pressurised the tank slightly until the fuel appeared at the engine bay pump inlet fitting and started up fine!

i was surprised as i had heard all the horrors about bleeding bla bla, but in the real world it isn't an issue.

as regards servicing, i just fill the new filter prior to fitting, never had problems doing this.
