So I bought the car after it had been sitting at the sellers house for 5 years. I got the car running and took it to a mustang mod shop to get the engine to run smoothly and to fix a misfire. I picked up the car yesterday and it drove great but when I stopped to get gas and filled the tank from then on the fuel tank has been buzzing constantly and the car rides much rougher. My guess is that when I filled the tank it stirred up all the rust and crap in the fuel tank which then clogged the fuel pump. I plan on replacing the tank and fuel pump and go from there. The car is a 92 gt with a cobra intake manifold, bbk cai, full exhaust, x303 cam, and I believe it has some sort of aftermarket head. The car had light blue injectors when I got it which I believe are 24# but after I picked the car up from the shop they had installed the stock 19# injectors. Some things I need help with that I wanted to ask you guys is: are those 19# injectors enough for my car should I switch back to 24#? Should I go with 155 or 190 lph fuel pump, and if i stay with the 19# injectors do I have to buy a new MAF that is calibrated for 19#? Something I should also mention is that the car backfires and pops much more than it used to. However I checked the fuel pressure when I got home and it all looked normal it was 40psi when the pump primed and 35psi at idle. Any help would be appreciated
