3.9 with later front cover, running on S.U's plumbing issues

[buffaroo]

Hi this is my first post even though i joined a while back, heres the problem. Just put a 3.9 with carb's into my 101 landrover. Now ive come to sort the plumbing out the later front cover has no take off's for the heater system like the earlier front cover has. I was thinking of taking a T piece off the top and bottom radiator hose's, to feed the heater/lpg vapouriser. Should do the job ?

On a P6B, the feed for the heater comes from the rear of the inlet manifold. The return feeds into the top of the water pump. The pipe from the rear of the timing cover accepts the thermostat bypass hose...which exits the manifold adjacent to the thermostat housing.

Hi,
Your idea is not ideal as there will be no flow until the thermostat opens and then the flow will depend on the restriction of your radiator.
Has your inlet manifold got a water outlet at the rear? If so, feed this to the heater and take the other heater pipe to the bottom hose.
If you have the later water pump, ie the type that runs anti clockwise, then it's possible to drill and tap the bottom hose ali snout for a 3/8""ntp connector and make the connection there rather than having a Tee in the bottom hose.

Hi Buffaroo.

The heater on a 101 takes it flow from the rear of the inlet manifold and the return to to a tee piece on the bottom hose, I think it's usual to tap in to them for the LPG water supply. Lots of specific 101 LPG advice over on the 101 club forum.

What ive ended up doing is putting a T piece in the top hose, going into the front of the inlet manifold. Then running a hose from the rear of the manifold, through the heater/lpg regulator back to the bottom hose (3.5efi item)

I think I may have solved the same problem, viz. a late (GEMS / Thor Range Rover P38) front cover and a carburettor inlet manifold.

Basically, the top hose is as-is, i.e. manifold to rad. No thermostat fitted.

The small hose on the front of the manifold I think I blanked off (will have to check on this one).

The hose on the rear of the manifold goes to a T piece. One branch to the heater, the other to the LPG vapouriser. The return from both these goes to the P38 bottom-hose thermostat. I fitted an expansion tank feed into the top-hose.

I'll check over the w/e.
