Spec is basically stage 1 but with a t34 was set up at Nms late last year so think the standard pump should b ok for that. As for wiring I used 6mm with a 20a fuse think the old wiring is also on 20a, but it's blowing 40a relays thing that's confusing me is if it is the pump then surely it should blow the fuse on my new loom as ther is no load on the old loom as its just a triggar now. Anyway I'll try your suggestions and report back, I'm on hols next week so if I do t sort it by then I'll take it to Nms as its due a service anyway.

Cheers for ya help
