 Now in 2010 we do not have a JBA Factory producing any vehicle that has been evaluated in any articles in the various Kit Car Press magazines or approved by VOSA BIVA testing.
Please note these are the old build pages from 1999 to 2004 when we had a JBA Factory in full production from 1982 that was regularly featured in the Kit Car Press and complied with regulations including passing UK Vosa SVA/BIVA tests and TUV tests in the EU.
A 2004 JBA Engineering Ltd Sports SR kit has passed the new BIVA test in June 2009.
Spanner Sizes
Spanner Sizes fits on the head of a bolt. 8mm spanner fits M5 bolt,

What You Will
Need
Fuel Piping 5/16 Kunifer for feed from tank to carb. Plastic fuel grade piping is
also available in both sizes.
Fuel Piping 3/16 Kunifer for return feed from carb to tank. Tube size may
vary according to engine installation.
Twin pipe clips for securing the fuel feed and return pipes to the chassis,
means you only have to drill one hole for each clip to support both pipes one on top of
the other.
Pop Rivet Gun, Pop rivets.
Jubilee Clips
Fuel Hose. All available from Local Motor Factor.
Fuel Tank from JBA Four types available or make your own.

Fuel Hose
Fuel Pipes must be secured
to the chassis at a maximum distance of 12 inches apart. Many
builders select a distance of 8 inches apart, well within the distance
allowed.
Where a pipe run takes a bend, it is advisable to secure the pipe just
before the bend and just after the bend.
Fuel Lines
 Follow the instructions in the Build Manual.
Only two lengths of pipe are required running in tandem, one on top of the
other. The tube size may vary depending on the type of engine you decide
to fit.
The photo above
shows the feed and return pipes fitted to the nearside chassis rail. Here
the piping has stopped and shows a male to male joint, which will be
connected to the engine carb or fuel management system, once the engine is
in place.
DOHC engine models with Fuel Injection have a different fuel pipe run which is also on
the offside chassis rail, the fuel tank also has the filler neck on the
offside. Remember to take this into consideration when preparing the fuel
pipe run on your chassis if you are using the DOHC fuel injection engine.
The procedure
here is to run the two lengths of pipe along the inside of the chassis and
up towards the fuel tank, as per manual. This is then connected to the
tank using small lengths of Fuel Grade hose to fit your diameter of
pipe, secured by jubilee clips. The engine system will determine the front
connections.
Fuel Tank
JBA supply four types of fuel tank, two for the SRi and two for the
TSR. These comprise of a standard tank for both models for normal engines.
Each model has an alternative tank for DOHC (Double Over Head Camshaft)
injection engines.
Only the standard tanks are shown here. There are four pipes fitted to
these tanks. The fuel filler, fuel feed, fuel return and the breather
pipe. Place a protective cover over these pipes, to prevent dust etc.
getting in. The difference
between Standard and the DOHC Fuel Injection tanks is the fuel filler pipe is on
the opposite side for the DOHC that is on the offside and the fuel filler
cap on the boot is on the offside.

Before you fit the tank you
will have to decide on the Fuel Sender this works in conjunction with your
fuel gauge on the dashboard.
Contact your instrument supplier and purchase the sender unit for the
gauges you will eventually use. You can buy this now, without having the
expense of purchasing the instruments at this time.
Use a highly reputable outlet. Greengauges and ETB are manufacturers of
such products. Links at the bottom of page.
You will have to make a hole in the top of the tank using
a drill or hole cutter, the size will be recommended by
the manufacturer of the sender unit. Clean out all the
filings from the tank and fit a cover over the fuel filler
pipe and other pipes, to stop dirt getting in. You will
have to connect the electrical wiring to the sender at a
later date.
Fit the tank following the build
manual. Always remember to fit rubber between the Petrol Tank where it
fits on chassis on top or underneath. Otherwise the tank will eventually hole with the vibration of metal
against metal.
You can cut up old rubber car mats for this purpose using double strips if
not thick enough. Another source is your local tyre depot. Ask them if
they have any old inner tubes from Trucks or Plant machinery.
Doug's Modification
Doug had heard from other
owners that when driving up steep hills with a low fuel level, the
remaining fuel would settle at the back of the tank, causing fuel
starvation.
To overcome this, he fitted a small sump to the bottom of the tank. More
Info.

fitting the engine, gearbox, prop shaft.
