Making space for the PI & starting of system install

Another job was to make space around the engine to allow the new exhaust manifold and PI inlets to fit properly. This meant the heater control cable was shortened, the under manifold heater pipe changed and a new clutch hose made.


For some reason I had a core plug that was failing, not around the edge/join, but leaking through it. Fortunately I had another one in my spares, so that was changed quickly enough.



The following day the fuel lines were all made up and complete to the metering unit, so the carb. dissy drive had been removed along with the fuel pump, which has been blanked off. It's all a bit tight round there, but fortunately does still fit in.


Around the other side the exhaust manifold is part on there for a trial fit, I needed to wind out the studs from the head to replace them with cap head bolts to fit the manifolds as the space looked tight for getting a spanner on and the inlet manifolds also required a longer fixing to mount them.


In the boot, the fuel pumps are piped-up and wired in, via relays. I want to get a fuel swirl pot in there eventually, but this should do for a start.

More PI preparations

Another job was to get the main fuel lines for the PI system fitted. I decided to use proper braided hoses instead of the original spec push-on plastic hoses One added complication was how to support and run the hoses. In the end I chose to make up some clamps to run down the outside of the chassis rail, which meant a bit of this X10.
and then a bit of lathe work with two pieces of alloy clamped together and drilled through to accept the hoses and through a different side for a mounting/clamping bolt. Ideally I would have drilled the chassis and used rivnuts, but due to lack of space (can't get the drill in straight) nuts were welded on the chassis rail and recesses made in the underside of the clamp to make it sit flush.

A good day was then spent fitting the clamps to the chassis, each one having to be fettled slightly to sit over the weld and also support the brake line.


The un-supported copper pipe is the existing fuel supply to the carbs. fitted up just to keep the car mobile as work proceeds.

Then up front, just before the toe board outrigger, a couple of supports have been welded on for the right angle hose fittings, which take the fuel to/from the metering unit.
