Engine mounts

[jack350]

Its been a long long time - bought my 350 in 1999, had three months of pleasure them main bearing went in the gearbox, removed with engine to commence restoration,13 years on now putting it back together with the aim to have it back on the road next summer (though thats been the aim every year).
About to return the engine and gear box to the chassis. question is this do the engine mounts (fitted to the engine) sit to the front of the moounts on the chassis or to the rear? i follow the forum all the time getting tips etc and alwas looking a pictures. may be when the engine gets in the bay its will be self evident?

For the sake of half an inch it won't matter: the propshaft is telescopic so it'll compensate either way. I think mine are to the rear of the web but can't check as the car's 12 miles away at the moment...

Mine are too the front of the lugs on the car - which makes sense as you would struggle to get the engine past them to fix from the rear.

Good point!

Thanks guys - will go for in fron although not a job for this weekend, want to do other finnishing touches to the rolling chassis, one job of which is to return the copper brake and fuel pipes that run fornt to rear.I know the fuel pipes run left and right inside the top tubes of the chassis held in place by tie grips but where along the chassis is the brake pipe attached?

I've just renewed my front-rear brake line; not sure if it was original but it ran from the small bracket above the diff, forward about a foot, then dropped down to the lower chassis rail and ran forward along that, then it went up the vertical tube just by the engine mount and into the m/cyl.
I've re-run it where you say your fuel lines are: straight along the top chassis tube. My fuel lines run along the offside sill tube.

I'd relocate them as a matter of some urgency to along the central chassis rails. If some idiot were to T-bone you or you spun off in to something solid, your fuel lines could easily rupture and if the pump is still running, there could be a major fire. Imagine you were knocked unconscious and couldn't switch the ignition off! The consequences don't bear thinking about.

You should be selling life insurance
From memory I am aware that the 'to' and 'return' pipes run along the top inside edge of the main inner tubes. The thing I cannot remember is the route of the brake pipe?
Your point regarding being hit though does raise a thought - is it common to have a kill switch for the pump?

[NaCl]

My brake pipe runs along the same route as the fuel lines. I replaced the fuel lines last year and followed the old route, as you say, inboard of the top offside main chassis tube.

I stand to be corrected, but I don't think any TVRs of our generation had fuel pump cut off switches, and my newer Chimaera didn't. In any case, the older types dont work at all angles of impact - usually front and rear only. I unfortunately have to examine a lot of crashed cars as part of my job (usually modern mass-produced models) and have never come across fuel lines (or brake lines, for that matter) running anywhere near the sills.
