Hello, I own a 760 turbo. I was driving it home the other day and it progressively started to die. It started with hesatation, moved up to surging, and finally died. It ran fine after a few moments so i tried to keep driving (just to get it home.) About 10 minutes later it died and would not stay running (it would start and die instantly.) I just changed the tank pump two weeks ago and the main a few months back. The tank pump quit working (again). The garage seems to think that is the main problem. Makes sence. However, when the tank pump went out last time, I probably drove 1500 miles or so before I changed it and during that time I never had and performance problems (just a very loud main pump.) They said that they also found a couple of lines (im guessing vaccum) off of the engine. I Don't understand why it would not run this time and would run last time if the same thing is wrong and why the new OEM pump would fry after 2 weeks. They said that the pressure is 50 psi at startup and instantly drops to 30 after startup. The filter and screen are also new and I have seen the inside of the tank and it is clean. Thanks for any imput.

P.S. After I installed the tank pump, I forgot for about ten minutes to put the fuse back in and it still ran fine. As of now I told the garage (supposed to be import specialists) to just replace the stupid pump if they are for sure that it is causing the problem.
