Now is the fun part, installs ,fabrication, break-in , and DYNO time

 

Nice... Looks clean.

 

Where'd you get the manifold, looks good. What are you using as a resivor? Where are you locating it, more details of this setup? Link of some sort to a faq.

Sounds interesting

 

lol just that manifold makes the engine look like its going to ****** mash..

 

damn it looks bad *** man.. cant wait to see some dyno results on that..

 

that looks awsome man congrats on that!!!

 

Thanks guys...well heres the set up that i am gonna be running in detail,



How to Build a Surge Tank

To convert some carbureted vehicles to EFI, we recommend fitting a fuel surge tank to avoid fuel feed problems, especially during hard cornering. This is also useful on many stock EFI cars which have poorly baffled tanks. The surge tank stores a small amount of fuel for the high pressure pump to pick up if flow from the main tank is interrupted for any reason.

Usually the tank is mounted in the engine compartment. Fuel is piped to it by either a stock engine driven mechanical pump or a low pressure electric pump. Often the stock electric pump can be used. A high pressure EFI pump will be mounted below the surge tank. The fuel gravity feeds into this pump and goes to the fuel rail. Fuel not used by the engine is returned from the rail, through the fuel pressure regulator, to the top of the surge tank. From here, if the surge tank is full, fuel is returned back to the main fuel tank. The schematic below shows a common setup:
Most tanks will have three fittings on the top, one for feed from the low pressure pump, one for fuel returned through the fuel pressure regulator and one for the return back to the main fuel tank. Usually only one fitting is used on the bottom of the tank for feeding the high pressure pump.

Tanks are usually about .5 to 1 liter in capacity, made from either steel or aluminum tubing. The tubing is usually 2.5 or 3 inch diameter and .050 to .075 wall thickness. A long tank allows any trapped air to rise to the top so it does not enter the high pressure pump. Threaded bosses are welded to the top and bottom caps or sides as in the example below. Usually 1/8 NPT or 1/4 NPT fittings are used but AN type fittings can also be used depending on your plumbing

 

SOMEONE ASKED ABOUT MY MANIFOLD well its a x02 fd manifold....these manifolds work great with a Dave aka guitarjunkie28 FD. No worries about getting cracks or rusted piping. The design is pretty straight through and good craftmanship went to this manifold some fd manifold need custom work in order for them to work.

Its also a divided manifold because my turbo is divided i want to have the max capacity of both my manifold and turbo hotside

 

FWIW, I have my Aeromotive pump mounted outside the tank and have not run into any fuel starvation problems until the tank gets very low (mostly a function of my pickup not totally reaching the bottom of the tank). I'm debating going to a surge-tank based design but can't decide where to actually mount it (it's ugly in the engine bay and there isn't really a good place underneath). Here's my setup:

 

Thank you AARON

those of you viwing now understand how this set up should work or look...keep in mind there are various ways to do it, for example look at aaron cakes setup he got a custom made tank adapter plate with an/ fittings on them

thats just a safer way to prevent future leaks in that area, because people will use the barb fittings instead of doing it the right way

 

so the walbro in the tank and Aeromotive on the feed line is how its done?

 

There is a good post in the Archives regarding designing a surge tank based system. It covers the setup fairly well.

 

just for inspiration, my surge tank setup could be seen here :

stock TII pump in tank and Bosch 044 pump in the pictures...

nothing wrong with barbed fittings and push on hoses
they have special clamps for them too

I've had the other style come off on my oil lines
I now pay extra $$ for the aeroquip store(in front of the fairground) to crimp my hoses with there special
aluminum crimp fittings

 

I most of North America, you can't run fuel lines inside the car (and for good reason too!). Otherwise the storage bin area would be a perfect choice.

 

well, in most of Europe u cant modify car at all...

 

Looking good man. I'ma try my best to get the corona up and running asap. And I might look into the fuel rails you used, they look awsome.

 

thanks Sammy

i cant wait till i get her home and start driving her...PLEASE lets do all of this before you leave on the float

 

If you have a single exhaust couldn't you use the area where the other muffler would've went? I has no idea where else it would go other than the engine bay. Also, Without and pressure going through the main pump, you could possibly use a fuel cooler inline there, has anyone else done this?

 

I think that part of the whole point of a surge tank is to have a source closer to the engine to supply the fuel easier. Putting a surge tank where the other muffler was just doesn't seem to help.

*edit*
Wahoo 2000th post!

 

theres plent of room under the rear of the fc you just have to find the right size surge tank and set up design

built safely of course

 

Not heard that before....
The surge tank is to help generate a constant head of fuel to the pump. I cant see why it couldn't be used where the other muffler was (assuming its mounted higher then the pump)

Cool build El Nene 7!!

Tell me what paint did you use for the painting the engine, was a specific heat paint ???

cheers

Interesting! I am thinking very hard about doing this. First thing is in the diagram I see one outlet on the bottom of the tank however in the picture of the actual surge tank I see two? What is the second one for? Also second thing is where do you get these suge tanks from? Thanks. Oh by the way your setup is bitchin'! I'll be posting my build up pretty soon and it includes a t70 and a hbp witch that turbo has been proven on a number of occations.

 

Yep, that's exactly something I have suggested in the past. Ignoring all those that thought it would make the car blow up (damn armchair fabricators) I think it's a really good idea. Lots of room when you remove one of the mufflers but it doesn't help us that have duel exhausts.

You can find the complete article here:

Surge tanks are available from most speed shops (Summit, TweakIT, etc.) or you can easily make your own if you have access to welding equipment.

 

cool thanks for the info man. Sounds like a good mod. I'm guessing I could use rubber fi hose and then where it goes to the external fp I could use stainless steel with an fittings correct?
