I had originally looked into this problem. I had gone through and used compressed air to flush out every fuel line originally, and I did it again after the original fuel pump began acting up. No change in the situation. As of right now I have the engine and transmission out of the car doing a checkup and evaluation of the condition, and getting ready to reinstall them and attach my Weber and plumb the fuel pump. Was trying to collect some info up front to save me the time of plumbing in the Holley and having it overpower the Weber. I should be fine, but I just wanted to get some information and opinions from other MG owners...I am actually quite happy someone responded, I usually get very little info outside of the MG specific message boards...Should have seen the guys face at AutoZone when I ordered a new set of points and condenser for the MG, he commented "What is a 24 year old guy doing with a MG, I thought you would have been driving something better..." To each his own I guess, and I know he didn't have any idea what else I have in the garage...
