UNDERCAR surge tank KE70
ok after seeing many many terrible boot installations of surge tanks i have decided to do a little tech article on my ke70 under car surge tank installation.
do not be afraid it is not as scary as most people think. and yes it DOES fit.
this works for ae86 as well (i have helped my mate do his exactly like this). you have a little bit more room in ae86, but not much.
this article does not deal with the selection of pumps or tank sizes, only the instalation.
For reference i have a facet type "rattler" lift pump, a bosh 96 something fuel pump (same as VL or close to) and a "EFI hardware" 600ml surge tank.
right onto the pics
first step-fuel tank out.
the following holds it in
-straps under the tank itself, 14mm
-few screws holding the filler neck rubber thing in
-the tank will not come out with the cap on
right fuel tank is out onto the fun stuff.
mounting the tank itself. i used 2 tech screws. not these screws come up inside the boot, so make sure you dont have anything in there you dont mind screws going into....
right now onto the other pumps, the lift pump can be mounted next to the surge tank. ensure that you keep everthing as close to the crossmember as possible, and as far into the corner. youll know what i mean when you stick your head under the car.
with the pumps ensure that you rubber mount them both as shown in the following pics. it will keep everything nice and quiet.
and here is a picture of it all installed without the tank in.
now onto the tank end. here is jsut a diagram of a ke70 pipe setup, its mainly for reference sake.
right now once you have everything setup chuck the tank back in and it will look something like this. sorry about the pics it was getting dark and i was over crawling under my car.
and thats it! easy! to make life easier i coudl have taken out the pan hard rod but it was definately do-able as it is.
also you might not fit a tank much bigger in there. but 600ml is enough for my little 4age.

haha seems exactly the same way i did mine. good write up
T18 in the build
Cool write-up man. will be following this writeup soon i reckon. only thing i'd suggest is using bolts rather than tec screws for the surge tank mounting.
same way i did mine, looks great
cheers mate
yer i thought about bolts...then i found 2 tech screws in my tool box..and had my battery drill in my hand....
seems to be working, its not ideal, but does the job!
im enjoying the quiet fuel pumps very much

thats the coil mount holding the fuel pump right? i use that to mount mine too
pretty much identical setup to what i had in my 20v, same pumps and everything
good write up!!
HAHAH I LOVE BOOST LOOSING!!

if your ever chasing a great cheap lift pump, ive been getting into the piersburg as of late, and they are fucking awesome. purr like a kitten, great rates and pressures, reliable as, heard nothing but good stories about them, can get them for 150.
good mounting, as said i would have used bolts but if it works it works.

yep you got it, fits good, had to bend it around a fair bit, but got it on there in the end.
ah yes my mate was telling me about these yesterday. supposed to be good.
that one that i have there is a facet i think, known as the "rattler". made a heck of a noise when it was first starting up, didnt like sucking air much. i almost replaced it with a carby fuel pump i have here (from an rx7). but once it primed itself its almost silent. i just get a faint high pitched noise from both the pumps, which i can only really hear at idle anyway as the exhaust is a bit loud...
just on a side note, the hose clamps to use are the "bolt type" ones. fair bit more expensive than the standard screw type, but they are so much better. i only used them on high pressure lines (as i only had a box of 10). but they are definately worth it. pluss i think to be legal with engineers you need to have them anyway.
