M1tch Posted October 27, 2020 Report Share Posted October 27, 2020 Are you running multiple pumps? Quote Link to comment Share on other sites More sharing options...
GrgG Posted October 28, 2020 Author Report Share Posted October 28, 2020 Yes running double pumps and i have deca 875 cc injectors and 4 bar fuel pressure the fuel is getting hot about 50°c Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 28, 2020 Report Share Posted October 28, 2020 That is pretty normal fuel temp, remember your metal fuel rail is bolted to the cyl head which spends its life at 90°C so it is going to conduct to the fuel pretty quick. It is unlikely your problem. As above, a log and your tune is really needed to help. Quote Link to comment Share on other sites More sharing options...
