Dick Twitchen Posted May 16, 2018 Report Share Posted May 16, 2018 Replacing the fuel pump on the GT6 and also re-routing with hose (R9) behind the engine on the the bulkhead. Struck me that if I rotate the top of the pump body then both inlet & outlet connections will face away from the block and I can then use hose tail fittings (in from the filter, out to the carbs) rather than tube nuts and olives. However, can anyone tell me the correct thread size and if this is feasible or not? At the same time I have work to do on the tank to pump line and it seems sensible to fit a fuel cut-off valve adjacent to the tank to ease maintenance. Any recommends for a valve that does not constrict with too small a bore size? Dick Link to comment Share on other sites More sharing options...

Dick Twitchen Posted May 17, 2018 Author Report Share Posted May 17, 2018 Thanks Pete, in which case does not seem compatible with the options available for hose tails (1/8 NPT or 1/4 NPT) through Car Builder Solutions and elsewhere. Staying with Triumphs original design at the pump then, but is there any reason why I should still not realign the top of the pump? Dick Link to comment Share on other sites More sharing options...
