A word regarding electric vs mechanical fuel pumps.
There is absolutely nothing wrong with the mech pump, throw what you want at it, dcoe 45? no problemo
So why electric? there is one and only one reason, in my particular case, I incorporated it into the security system, in other words unless you know the secret hand shake ......the perp will be stalled in 50 feet or so with no fuel.
Regadess, and as been my experience a few weeks ago I have been driving the 240 and it died about 1/4 mile from my house as if its out of gas, which it wasn't, reluctantly I have suspected the supply hose/s at the fuel tank, both were 100% original and super brittle, both got replaced.....yet the problem remained. finally, I replaced the hose from the fuel rail (100% original)(pass side fuel rail to the fuel pump) and that did the trick.
Moral of the story: Don't wait 45 year+ to replace any flexible rubber fuel lines, the factory stuff may last that long (not) ..but aftermarket?
