Busa build questions

[peterrosey]

I'm building a Megabusa and have a few questions - the busa build manual supplement is truly dire (it explains how to fit the ally panels, RGB, gear-linkage, rear diff and, er, that's it...). Any help would be greatly appreciated.

1. Speedo senser - Westfield say there are two ways to attach this (can't use OE position as there are no allen bolts on Freelander diff UJs). Either araldate a bolt head to the UJ (can you believe they said this!! Imagine it coming off like a bullet at high rpm! or use a bracket mounted near the handbrake cable support to pick-up on the propshaft bolt heads. I've done the latter and used a steel pointer as a washer around one of the allen bolts - will this work?

2. Fuel pump mounting. The megabusa pump is a cylindlical pump mounted fore-aft alongside the diff casing using a bracket similar to a coil bracket. But it seems a bit exposed and not in an ideal  place - any better ideas on where to locate it? Does it have to be mounted below the lowest level of the fuel tank to get a gravity feed?

3. Fuel tank breather. Also there's a red aluminium breather outlet on top of the fuel tank for a breather - does this just need a breather hose ducting off it, or does it need to be plumbed to a specific point (again, no mention of it in the manual).

Thanks for your help on all these - so far I've got the car to a rolling chassis stage and have marvelled at the manual. So much of the stuff is only applicable to CECs. Without taking loads of pics at the factory, I wouldn't have got very far at all!

I can try and answer 2 and 3....

2.  If it's a high pressure fuel pump then ideally it should go below the level of the tank.  High pressure pumps don't like sucking air.  If the engine is fuel injected it's likely to be a high pressure pump.  If it's on carbs then it's probably a low pressure pump which doesn't need to be below the fuel level in the tank to work properly.

3.  The red breather is just that - it just has a length of hose attached to it (no clip needed) and then cable tied up the chassis tube running up to where the suspension pick-up points are.  Make sure you bend the tube back on itself so any water or road grit doesn't get in there, i.e. point the open end of the hose downward and towards the back of the car.

Thanks Nick - I suspected that'd be the case with the fuel-injected pump, but it's good to have confirmation. I think I'll make-up some kind of nylon skid-plate to protect the pump and the fuel lines, though.

If you get really stuck, I may be able to help, give me a call, just finished one for a customer.  Brace yourself for the SVA, the car we did failed a few times on emissions.
