So far for the swirl pot installation, I've uninstalled the old fuel system (see earlier article) and installed the new lines and swirl pot - but I'll need another length of hose and connectors to finish. Finally we need pump and connections.

Here is a fused relay, this takes a signal from the in tank pump (converted to a low pressure lift pump) circuit, and activates power direct from the fusebox to the fuel pump.

At this point I'd used a certain gauge cable (seen above in blue), but got a bit scared reading posts suggesting stupidly high amp rated cables. So I switched to what I think is a sensible 27 amps rated cable for the high pressure Bosch 044 pump. Still need to bolt it properly, but I need another hand!

I'd bolted the pump somewhere sensible, and fixed the relay. I still have a bit more work done but nearly there.

Bit more cable tidying to do, and to connect the relay signal wire.
Just a couple of pictures to fill time, as this weekend I'll be servicing the family Fiesta. I'm out of budget until next month to get more fuel hoses... I have realised already that the fuel filter needs to sit between the swirl pot and the lift pump / the original tank. swirl pot e30 swirl pot e30

Being around 60 kgs overweight (mostly the car, honest!) is something I can do plenty about, so that's the main winter job - more later. The inlet manifold came off so the injectors could be sent to injectortune.co.uk for a fast efficient service. Before they were sent off:

The nozzles are now very clean as seen below!


 

Hopefully that will give the engine a bit of a fairer fight. I game it a good clean with brake cleaner and a couple of new body gaskets. Its all back on now.

E30 Inlet manifold

I've just got to get another replacement hose (this time a crankcase vent hose that goes under the inlet manifold to the throttle body) and connect it all back up again. Getting there...

I've also been sorting out a swirl pot - I noticed a really bad case of fuel starvation at Oulton especially coming out of Druids, even with half a tank of fuel (there's a dent in my fuel tank which probably doesn't help). That's 25 or so kilos we can get rid of. Downside is it's lots of fiddling around with the fuel system... so I took the plunge!

E30 custom Fuel Pump

It took some fettling after this, because it just has to be at the right height so the sock is submerged in fuel without being flattened. Fingers crossed...

Here is a low pressure lift pump attached to my existing cradle. So gone are the old grotty fuel lines:

The last one here it turns out was the vent pipe - seemed odd at the time it went all the way up the car passed the engine to a rubber hose to nowhere. In the bottom picture it's the most left hose connected to the steel one - now it isn't. The fuel filter needs replacing anyway, that will probably relocate too.

The hoses here now have to be directed to the boot where this is now waiting... that's for the next update!
