MECHANICAL vs. ELECTRIC FUEL PUMP on 2F

mechanical pump for sure , they are way more reliable , easy to change and cheap .

of course i don't run a 2f , but the one on my small block has never given me problems .

i have changed several electric fuel pumps on trails / parking lots / side of the road / gravel pits / basically any were . i hate them , a good one is inside the fuel tank so that it is cooled properly . of course this makes it 5x more fun to change .

stick with the mechanical pump . buy a good oem one and carry a spare if your worried about it .

I run both, I use the mech factory pump as a lift pump to the surge tank and a bosch pump from the surge tank to the injectors.

The factory pumps are very reliable I have no issues using it.

On my 74 F I run the Kyosan mechanical and a belkamp electric pump inline just before it. I use the electric to fill the bowl when it's been sitting a while and goes emty. With the bowl filled I shut off the electric and it cranks right up. I run it on the mechanical alone but the electric is always there for a backup. 8-9 years with this setup on the aisin carb with no problems. The Kyosan just did start to drip so I just put on a new one. I'm also just now trying out a Weber 32/36. and I did the recomended fuel regulator but I couldn't get more than about one pound psi. So I ditched the regulator and I now get 3 - 3.75 psi with either pump or both together so again I'm happy with the dual pump setup.

It happened because you were not running the spacer between the pump and block. I also vote for mechanical. I am still running the original pump in my 79 and just carry a spare for when it dies one day.

Nope I had the spacer in. The old engine is dead so I might go back with a mechanical on the new 2F. I wonder why mine broke? Original broke in NY so I replaced with a cheap get-me-by for the time and it broke again in Georgia with only around 2-3 thousand miles on it?? I'm wanting to say I broke a third, but I could be wrong. I do think the electical I have on (cheap $30 quick fix again) is lacking enough power to pump the bowl so sometimes I get surges if I punch it too hard.

on my 77 I still have the oem and it has done wonders for me. I have a carter carb and it mine also surges every now and then but I think it is from the carb itself not the pump. I vote Mechanical all the way unless you are running a top fuel drag car. Wich we all know that the 2f's are pretty close to being, lol

Are the mechanical fuel pumps the same on all 2F blocks? or did they have a minor change between the older ones and newer ones? Also where do you source your mechanical fuel pumps from? Next time I'm getting an OEM if possible or whatever is the best equal. Thanks
