Difference in fuel pumps?
I'm not a fan of mechanical fuel pumps since they have a fatal flaw of potentially leaking fuel into the engine oil. Electric is the way to go, IMO
Wait what? I have to call it the lessor of two evils.
I heard your opinion, and I raise you;
First; since 1969, I personally have never had a diaphragm rupture. And I have been driving carbed cars for all of those years.
Second; since 1969,the only instance I have ever heard of was one guy here on FABO. Now I'm not saying it doesn't happen, just that I only ever heard of one instance.And I haven't been wrenching on cars for all of those years, perhaps only 35 of them.
Third, and most importantly when the diaphragm ruptures, the engine more or less quits running. Then you fix it and change the oil. Yeah, I suppose a grandma might drive hundreds of miles with a small leak, and never notice it. I'll give you that.
Fourth;
IMO the electric has a the worse fatal flaw, cuz if a situation develops, that pump can push all the gas from your tank,into your engine, at the rate of perhaps over 100 gallons per hour; say 1.8 gallons in a minute, or about 1 ounce per second.(Ok maybe not that fast on a QJ,lol) And the gas may not,will not, end up just in the oilpan, like a mechanical pump failure.Most of it will end up flooding the cylinders, the pipes, and the mufflers. Perhaps you bend a rod on the next restart;you know those SBM chambers at TDC, only hold about 75 to 85cc or so,or about 5 cubic inches.
And I have heard of several instances where this has happened, since 1969.
It is also
my opinion that in either case, it can be dangerous,catastrophic,or even deadly.
No E-pump for this cowboy.
