For Those Running Intank Efi Setups

[turbo_rolla]

Converting my "surge tank" setup on my 4age ke70 to intank to get it through Regency here in SA. Have got a VL intank pickup feeding to a VL external pump. Have mounted the intank pump and done a test run without the tank etc mounted, and it ran fine. different story when i mounted it though given the bends etc in the hoses, as it coughed and spluttered and stalled.

 

Question is, where have you guys mounted your exteral pump? i want to stay away from tight curves etc obviously, so guessing the area around where the tank mounts up isnt realistic? Or is there somewhere i can put it in there?

 

Thanks in advance.

We mounted Teddy's surge tank and pumps in his boot, Eventually we will make a cover for them..

Sure the hose wasn't being squashed or anything ?

 

VL pressure pumps don't like sucking the fuel up, Maybe the low pressure pump lines got kicked or something ?

I had the surge tank and pump in the boot previously but because i've got to take it through regency to show it meets their "statement of requirements" and hence be legal, i need to move it out, which is why i've gone to the in-tank lifter pump

 

AE70, turns out that the wiring had f$#ked up - while it was all lying on the ground it was fine, but as soon as there was some angle on it the pump didnt like it like you said. Ended up dropping the tank down again and re-did the wiring and all is good now (actually had the vl pump running into a bucket (the pre-pump in the tank wasnt engaging, but is now), so i know that's working.

 

The problem is finding a spot under the car where its safe, keeps the pump horizontal, but also doesnt give any kinks in the hose. So that's why I'm chasing ideas on where to stick it under it :hmm: Am happy to use lots of hose if required, but would like to keep it close as possible to the tank

I made a 2 piece cro-mo bracket for mine, a bit obsessive I must admit.

 

picy:

 

 

 

 

I have heard of above one of the axle tubes of the diff under the floor, on the bottom of the car or cable tied next to the tank

 

 

 

edit: oh and I made it two pieces so the fuel tank doesnt hit me in the head when I install it. Have a look where it bolts up to see it.

S#!t, that's heaps fancy sam! Nice work, looks like it'd do the job nicely! Unfortunately i don't have the patience to slap something like that together :hmm:

 

Rang transport SA today and spoke to one of the guys in the "Vehicle modification" section. I queried whether i could mount it just after the chassis rail, by chopping into the metal lines and mounting the pump in a kind of protective case near there. They said this would be fine as long as it wasnt anywhere "dangerous", which he didnt seem to think would be a problem. So i'll jump under the car on the weekend and see what its like. I think that'll be the way to go though as it'll be a bit easier and less fiddly :cool: just gotta make sure the lines are clear of petrol before i go at it with the grinder :hmm:

sounds like a plan, because you wont have a barbed line anymore I recommend atleast two proper efi clamps spaced a decent distance apart. You shouldnt hav emuch of a problem because there heaps of room spare. One thing though, itmight be a bit late but if you can use the complete rubber mounted assembly you will be infront in the noise depeartment, dunno if you care about that though.

 

Also I really would prefer you using some sort of hand cutter, remember an empty line or tank or more of a hazard than a full one, and I really don't want to see you getting hurt.

hacksaw FTW!

[turbo_rolla]

yeah, I'm thinking that'll be the safer bet - its not that thick a pipe, so shouldnt be a problem! Got plenty of EFI rated hose and clamps so I'm happy to chop a section out, run the hoses and mount it somewhere securely :hmm:

[Sam_Q]

use a fine tooth blade or else it will get stuck as you try and cut it. Keep a fire extinguiser and a friend nearby if possible.

[turbo_rolla]

yeah, will have someone there with me, but fully intending to flush the line of petrol before hand - whats the best thing to use? was gonna blow out whatever i could with a high pressure hose - will that be enough?

 

Just for reference, this is what i was running prior to a couple of weekends ago:

Was never comfortbale having all that in the boot, and the noise of the pickup was annoying :hmm:

Teddy's Setup..

looks good - the inboot installs are good for the race look, but i was over it in a couple of weeks, plus the noises.

 

I'm gonna also redo my sound deadening under the carpet with the new setup underneath just to try and reduce the in-cabin sound a bit in general - looking at this stuff here (Sound proofing)

.

$100 delivered for 2x 900x1500mm rolls - about 8mm thick, and each weighs about 4-5 kg, so would do the job i reckon, unless someone else has got any other suggestions?

It can have quite a lot to do with how much load the pumps are under too..

[Sam_Q]

Jaycar have some stuff for sale too,

 

if you use the original Vl rubber mounted holder it should quieten it down a fair bit though
