Title: Nickel plating or other surface work.
Post by: NeoTech on December 23, 2015, 03:34:54 AM

I have the need of making a surge tank for my street car. Its basicly a 3-4l extra tank in the engine compartment where you mount a secondary high pressure pump for the EFI system.

Now been pondering, im running E85 in this car. And what would stand up to that. Stainless of course.. Aluminium? Maybe even  nickelplated steel??
Think the easest would be 1.2mm sheet metal basicly and then have it nickel plated.. Cheap, easily available easy to work with.. But E85 and steel - i dont want rust in my engine. =)

Not easy to plate the inside of a tank successfully.

There are epoxy  resins designed for lining fuel tanks..perhaps having welded up your steel tank you could swirl a layer of that inside once or twice ?

You mean those "tank sealant" products maybe? Are they epoxy based? *googling*

Road transport tankers used to have fiberglass on the inside , the metal was just for support .

This sort of thing:

But there are many more. Many decades ago I sealed a friends Triumph TR3 slab tank with ordinary polyester fibreglass resin, which held up for the seven years he was training to be a doctor. But ideally you want something slightly flexible to absorb the ocassional knock and bump

If I recall correctly early Ginetta G15s were made with fibreglass fuel tanks.

yeah im gonna give that a try - seems fairly cheap for the price and im only making a really small tank so. Should work. =)

I think that fibreglass will degenerate with any ethanol content in the fuel. Google it to check.
