I am building up my TPI system and I took at apart sometime ago to get things painted, polished etc etc. I am now putting it back together, BUT I can't remember which o-ring goes where.

I know the 4 same ones are for the front tube that goes straight across but I can't remember where the other 4 go on the back tubes and regulator AND what the large one is.

Can someone help out with this? I can't even find a diagram or anything.

Thanks

 

the large one is for the cold start valve if you have a 85-88 and the other is for the line feeding the cold start.. the other two small ones are for the inlet fittings. but usually are wrong.. the other 4 same ones are for the crossover tubes
