DMRL Posted September 6, 2022 Report Share Posted September 6, 2022 Hi All, About to run new fuel line from pump to carburettors - my original pipe runs between the thermostat housing and rocker cover ( see pic attached ) - looking on-line most people seem to have it run around the front of the enging and clipped to water pump housing - has anyone else got the same as me? any reason not to copy was was on the car originally? All help gratefully received as usual. David Quote Link to post Share on other sites

gloide69 Posted September 6, 2022 Report Share Posted September 6, 2022 The fuel pipe on my car was routed like this, and in my ignorance I copied it when replacing it. Do you think there is any disadvantages from leaving it like this? Quote Link to post Share on other sites
AndyR100 Posted September 6, 2022 Report Share Posted September 6, 2022 Mine runs the same way - was like that when I got the car and has stayed that way, can’t say I have ever had issues because of it. ………. Andy Quote Link to post Share on other sites
stuart Posted September 6, 2022 Report Share Posted September 6, 2022 In theory running it under the thermo housing means its running in the cooler air stream from the fan, behind it is between hot thermo housing and hot rocker cover. Stuart. Quote Link to post Share on other sites
Charlie D Posted September 6, 2022 Report Share Posted September 6, 2022 Andy, Unless I’m missing it I can’t see any actual support where your pipe is fixed to the engine. It’s fixed at the pump end, because it goes into the pump, but the next place seems to be the rubber pipe. I’d be a bit concerned that vibration, over a period of time, might fracture the pipe where it enters the pump. The normal method is to fix it to the thermostat housing via a metal p-clip. Makes it all a lot more rigid. Charlie. Quote Link to post Share on other sites
Drewmotty Posted September 6, 2022 Report Share Posted September 6, 2022 (edited) Run as you have it provides no support between the pump and carburettors and risks a stress fracture due to excessive movement. It should be run in front of the thermostat housing using the correct support bracket attached to the bottom thermostat cap nut and the rubber insert to support both the fuel pipe and vacuum line. Edit: it looks like Charlie can type faster than I can Edited September 6, 2022 by Drewmotty Quote Link to post Share on other sites
DMRL Posted September 6, 2022 Author Report Share Posted September 6, 2022 Hi guys - re fixing if you look closely in my first picture mine has a support bracket that goes under the thermostat housing bolt so pipe is held firm Quote Link to post Share on other sites
Lebro Posted September 6, 2022 Report Share Posted September 6, 2022 OK, missed that ! It should be fine in that case. Bob Quote Link to post Share on other sites

gloide69 Posted September 7, 2022 Report Share Posted September 7, 2022 Thanks for the feedback, I've now rerouted my pipe to give it the correct support Thanks Paul Quote Link to post Share on other sites

Apologies Andy. I saw the picture and thought it was yours. Comment was meant for Paul. I'm easily confused these days. Quote Link to post Share on other sites
roy53 Posted September 7, 2022 Report Share Posted September 7, 2022 As Stuart has posted [ no surprise there then ] the pipe goes under the front of the thermostat. See TR2 general details drawing in the workshop manual. Roy Quote Link to post Share on other sites
