Outer Limits 4x4 Board

So hopefully over the Xmas break Ill be converting the Paj to EFI
And am just wondering if people have had particularly good or bad experinces with certain types of pumps. Just to clarify, these are going to be filling the surge tank, from the main tank.

My original plan was to use the little solid state "Gold Cube" style pump, u know the one that goes "tick tick tick tick tick" when its operating, good? bad? reliable??? I remember having one on a paddock basher as a kid and it went for years and years and was run dry serveral times, worked right up untill my brother hit it with a hammer, so I figure there pretty good.

There is also the newer style of solid state pump that i know little about, but its more of a rotary style and doesnt get the "tick tick tick" sound going, good? better? worse???

I have always found the Pierburg 810 to be an excellent pre pump. They are compact, quiet and very reliable.

On performance vehicles I've always used a carter black or gold pre pump, and one or more bosch 440's. have used holley pre's before. Had a few dramas.
Never had a problem with carters.

I'm using one of the fedtro solid state types. Too fricking loud, I would like to find something less noisy. Does the job though.

i have one of the gold cube ones and not failed yet and dont expect it too for a while.

they are noisy but depends on where and how u have them mounted.

Is the Fedtro of reputable quality, ive seen a heap floating around on the Bay and assumed they were a facet knock-off...???

Do u hav yours rubber insulated??? Or just mounted stright to the body???

I would suggest the smallest pump that will supply enough pressure and volume, putting anything larger in is a waste of money and will just create too much noise.

Maybe a Pajero pump would be the best for your application.

Why not just use an EFI fuel tank with the pump built in.

Agreed if you can. Tank will be properly baffled too negating the need for a lift pump or a surge tank.

I use a Facet 4-6psi job supplying my surge tank then into a VL Turbo fuel pump. The facet is a little noisy yes but its a roofless 40 which is not exactly quiet.... It's been going for over a year now with no dramas.

Factory Pajero pump is mechanical

Tried going down that route, all I could find was LWB Pajero tanks which are 90Lt vs the shorty's 60Lt, plus, even if I found a tank and pump that would suit, whats to say the the pump would be a goer, it may need replaceing, thus being as dear as a surge tank + 2 pumps.

I will be using a similar unit I think.

mine is mounted to the body with a rubber insulator in between

Even on an EFI Paj?

Having done an EFI conversion, I will only say that if there was a factory made tank that dropped in and had an EFI pump onboard there is no way I would dick around with surge tanks and lift pumps etc. It is definitely not worth it if you have a factory option instead.

You could try a hilux one from a 3rz motor etc. I think they are around 60-70 litres. Can't be that hard to mod. Keep it simple.

Even on an EFI Paj?

No, sorry, defo not on an EFI paj, hard part is finding a shorty EFI paj with a tank that will fit!!!

Ive done it now, Ive bought the little gold cube lift pump (Fedtro) and made my Surge Tank (Sexy as in Stannless!!!) looks very nice if I do say so.

Thought about fitting a different tank out of something else, but, realistically, whos to say the pump in that tank wont be FUX0r3d anwyay, so id be up for more parts, as it is, im using the factory in tank Magna Pump which will be mounted inside my surge tank, and I know it works as I drove the car 300 Kays to get it home..

Anyway, we'll see what happens next week, might even do a build thread on it if all goes to plan!

I used a VL Commodore pump in-line in a warmed over FI 5L V8 conversion I did and it worked treat. Did not use a lfit pump and simple to figure out installation and pretty cheap too.

I ran an EFI conversion the same way for a while, in fact with the same pump. It is not an optimal set-up though as you can lose pressure in the fuel rail when fuel sloshes around in the tank. EFI tanks have a surge tank section built in for this reason, or else EFI setups have a surge tank elsewhere in the system.

I am sure you could run without one indefinitely without any problems but I decided to tidy it up and add a surge tank and lift pump. I also ditched the commo pump and put in a gruntier one but this was just because I got one cheap (bosch 909), it was not really essential.
