im mid way through my 4age into a sprinter nd would like some conformation on a few things before i commence any further.
im up to the fuel system..havent had experience in this so i want some confirmation so i can be at rest!!
im using a VL fuel pump and plan to mount it between the metal fuel lines and fuel tank.Is there enough room here.Where is the ideal place for the pump >>a picture would be great.
also i plan to replace all the rubber hosing.is this needed? or can i just replace the main hose that goes to the fuel pump
i assume that the metal fuel lines can carry the needed amount of fuel to the engine.
lastly can someone give me the model number of the fuel filter i should use.or a picture of your setup??
thanks in advance for any advise/guidance / criticism ..
if you can think of anything that may help in this area please post away

I bought some fuel filter called "Cooper" from autobarn. Part number = WZ309
Yes you do have to change all the rubber hoses, if you don't, you'll get a very nice suprise. Be sure to get the right clamps for it too.
Make sure you buy EFI hoses, I bought these "EFI" hoses from this dodgy family-run business in Cabramatta and they broke on me about 4-5 times. Lucky the first 2 times I wasn't far from home, so I risked my ass and drove home to fix it. Now I have spare fuel hoses and clamps in my car just incase it does it again. I recently replaced all of them for the ones I bought at Repco, never had a problem since. $20-ish a metre from what I remember.
Oh yeh, I haven't checked recently but from what I remember, the fuel filter I use, the top and bottom ends are different in size.
Hope this helps.

yep im with oldcorollas...track down an AE82 intank fuel pump, all you have to do is remove the pump, chop the bracket in half, extend it a bit and extend the two wires to suit and then replace the fuel pump in the bracket and it bolts straight where the old 4AC one was!
and if you still have your interior in it is silent! if you don't it is just a quiet whistle that disappears as soon as you take off!
So much easier than chopping fuel lines and creating brackets.
I left my carby fuel lines on at first and they lasted abut 1/2 a day then came off cause I had normal hose clamps too.
Went to pirtek and bought a few metres of efi fuel hose from them and a handfull of efi hose clamps(get enough so you can use 2 clamps on some hoses-the return line is thinner than the other lines) and I havent had a problem since!
if you are staying N/A don't throw valuable conversion money away on a VL pump, should be able to do AE82 conversion for just under 100 beans, including hoses and clamps!
And with fuel filter I just went to my local auto shop with a cutoff of the EFI hose and got an EFI fuel filter with the same size fittings on both ends and used the cutoff EFI hose to get the right size! Just let me know if u want a part number?
Goodluck with ya conversion!

I used the sv12 camry in tank pump (DON'T!!! the top doesn't fit!!). Yes it is quiet, and yes I did mount it as low in the tank as possible - but it surges horribly for the last 1/4 of the tank.
A friend on the other hand used an in-line pump between the tank and the metal hoses - fucking annoying sound (comes from everywhere), but using the standard 4ac fuel pickup, it only mildly surges after the fuel light comes on (when mine surges the engine looses ALL power).
Just have a look at how many holes and diameter of the standard fuel pickup cap thing before you go buying something from a camry.
as you can see from my pic, you don't need to cut anything, just flatted out the bottom support (or cut it off...) and hoseclamp the pump on at the desired height (use two if you are paranoid) extend the hose and wires and you are done... poke it in the hole, if it fits, lower it, if it doesn't raise it etc.

Edit: might be worth checking if an aw11 one will fit first, I'd say they'd be the same but best to be sure.
 It's the one on the left.

Hey, thats identical to my Cressida before and after with the walbro.
Down to me putting the brown plug on the factory fuel pump!

thanks for the responses
i did first buy an ae82 fuel pump but went with a vl one instead.
this was because i would of had to bend the main fuel line on the pump as it was in the way and the pump could not go in the tank with it in its original shape.
the fuel pump and filter are all in and soon should be able to start the car up and test it....
got to wire up the alternator and the coil and do some work to the throttle linkage

All you had to do with the AE82 pump was cut up all the metal fuel lines from the pump leaving enough room to clamp EFI fuel line over the end and connect it to the existing metal fuel lines.
Ah well if its all in now then no worries!
But if you run a surge tank between tank and VL pump use the 82 intank as a lift pump, that was my original plan but I dont need crazy amounts of fuel and dont suffer from surge so I never got around to fitting the VL pump or surge tank!
Hope it all works out for ya!
Cheers.

i'm sorry guys just a few questions.
Is the orginal 4AC fuel pump mechanical or electrical?
Does it mount in the fuel tank or in the engine bay?
I ask coz my fd who is doing the conversion for me thinks the old 4ac fuel pump is mechanical and he says he's planning to mount an external pull type pump in the engine bay about the fuel filter position. He said this would make it easier to fit coz it doesn't require to modify the fuel line.
anyone knows if it should work fine pls help coz I've never heard about this thing or can anyone tell me any good or bad in doing this.

4AC originally has a rotten little mechanical one on the engine.
On my KE70 I used an old Mazda electric carb pump as a lift pump, made a little swirl pot by welding a couple of ends on a piece of old tailshaft (any piece of 3" pipe will do), used a VL pump to do the main work (actually used an old Cressida one, but it failed from old age, so I replaced it with a new one), used a carby type plastic in line filter before the lift pump, Z200 (I think) EFI filter after the 'main' pump, and a bunch of fittings, hose, etc. from Pirtek. Didn't take long to do, lets me run the car until the tank is bone dry (i.e. if you get any fuel surge, that's it, you're right out), and I didn't have to touch the original tank, lines, hoses, etc. at all.

i know realise i was better off using the ae82 rolla pump but didnt want to frig around with lengthing brackets and the like.
my vl pump is held on by an old fuel filter bracket and a fat clamp round the whole works.. will find out soon if it all works!!
damm tafe has started again so ill have to wait till next week to finish my project !
oh yeah in case is doing putting an efi fuel filter in there sprinter i used an sx fuel fiter, mounted in the same location as the old and got the banjo bolts from a wrecker, enzed can supply the other fittings.. pretty simple really..
should have a twin cam sprinter very soon though!
