1st GEN Celica Surge Tank Ideas

[YLD-16L]

I imagine they can only be 6" tall or so? So not a lot of volume?

Mine has a volume of about 1.65 litres, no surge issues what so ever. The surge tank is approx 164mm in height.

As for a seal the other option i was thinking about was strips of rubber glued to either the lid or the boot floor,

That was another option I thought of too. You can pruchase lengths of rubber weather strip from the hardware store in various thickness and with an adhesive backing on one side. I went with the vac tubing though because it was easy to make a single continous seal in any shape with only a single join and no kinks.

this might be a stupid question but is fabricating an in tank pump not an option?

There are no stupid questions only stupid people Just jokes. I thought of this option too but it meant too many mods to my 33 year tank for my liking and I don't want to blow up or catch on fire Some tanks might be easier to mod than others?? Or may have an efi model equivalent which a tank can be borrowed from.

thats it were talking no welds fuel setups here.

no fun in paying some1 to make it!

Never welded a fuel tank?

[RA23]

Another stupid question: could the surge tank be located under the bonnet?

[SillyCarS]

There is enough space inside the rear quarter panel, next to the tyre well...

i dont suppose his would be a good location in case of a prang would it...

just a thought

Yes it can, just depends how much room you have in the engine bay and how much "stuff" you want in there.

Never welded a fuel tank?

We welded a fitting onto one the last week, got to take care doing it though. The tank was thoroughly cleaned and had been sitting open for over 2 months. We still ran an exhaust through it to be safe.

or you can just empty it and fill it with water, its only the fumes of petrol that burn

[timbosaurus]

and water neautralises petrol....

Why not just mount a surge tank under the car along with the pump, filter, and whatever other goodies you want. This will achieve 2 things:
- Help minimise the fuel pump noise inside cabin
- And reduce smell.

Plus in cars like the 86 and celicas with the hatch the fuel stuff must be covered so if u put it under the car i think you get yourself out of having to build a sealed enclosure.

I'm starting to like the underbonnet option. Do people think heat and other under-bonnet nasties create an environment that is not particularly suited to storing a litre of petrol and petrol vapour?

I think the question is *where*. We've seen one ingenious idea of taking the muffler space for it, and another which tries to eliminate the surge tank.

It seems we're trying to find little certain little nooks and crannies in the stock body of a 1st gen that are well suited to a surgey.

Has anyone ever really gone down to pickkies and looked at EFI tanks the may fit in the RA28 rear? This may be a simpler solution if there is such a beast. RA60, 65

Stews setup is good but there are questions on how quite you can get the exhaust in that shorter run.

I'm looking into drop tank but that is mainly because I want room where the tank currently is.

[TurboRA28]

I tried a RA65 tank but it was too deep. The 28 tank is pretty much flat on top, but the RA65 tank had a big protruding section another 20cm higher or so where the pump goes in.

and if you go down this route and get a custom-made tank, you can get baffles put in where you want and go to an internal pump (e.g. walpro) as found in most supras these days.

The safest way to weld a tank is to flush it with water and then get a bottle of mig gas and a regulator and purge the air out of the tank with a reasonable hit then keep a small amount running through tank while welding.

Has the extra benifit of having less chance of pinholes in welds.
