S2A109RAG Posted August 14, 2008 Share Posted August 14, 2008 I have two fuel tanks(under seat). is there an easy effictive way to have a switchable fuel pump to get the fuel from either tank via a switch. Rather than the old brass tap and almost always having to use the primer pump to get presure back. (being Diesel) Thankyou. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 14, 2008 Share Posted August 14, 2008 You could fit a a T-piece and draw fuel from both tanks at the same time or have an electric pump for each tank and switch from one to the other as necessary. Les. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted August 14, 2008 Share Posted August 14, 2008 A single electric pump after the brass valve could also work. Quote Link to comment Share on other sites More sharing options...
kingdong Posted August 14, 2008 Share Posted August 14, 2008 Hi all i am going to fit twin tanks when i have finnished the engine conversion as for the left hand tank was thinking of using an electric pump to transfer fuel from the left tank into the right tank when the right tank starts to get low no need for a tap. cheers graham. 1962 s11a swb was a 2.1/4 petrol now its a 200 tdi.

Phill B Posted August 14, 2008 Share Posted August 14, 2008 Why not use a two fuel solenoids each one connected to the fuel pipe from each tank and in turn connect to a switch. You could removed the brass switch all together then. Quote Link to comment Share on other sites More sharing options...
david1701 Posted August 15, 2008 Share Posted August 15, 2008 replace the brass valve with a switchable T and use an electric pump, or two electric pumps then a fixed T. If you wanted to be clever it would be doable to put sensors in the tanks (ie electric fuel guage sender) and have a micro controller decide which tank to use.
