i traced my problem to weak fuel pressure at number 8 at the distribution block, all have pressure at idle except this one. what should i do, i may have screwed up cause i took this apart, thinking it would be easy. thought it might have trash or something in it, but i cant find parts to rebuild this thing. everyone wants to sell me a reman. is there any hope??? has anyone tackled this thing??
