Drew a nice picture (fuel)

I have an electric pump to replace my mech. pump. It's bought. And I can't take it back. So pls. don't tell me to [img]images/graemlins/grin.gif[/img]

Is this a good way to hook it up.. and do I NEED the return line setup (red)

The pump says it puts out a couple lieters a min.. and 1-3lbs.
Is this sufficient.. and if the carb doesn't use all that flow.. (MC2100) will it just backup and stop pushing? or will it force itself throug the float into the engine?

1. The fuel pump pressure should be OK.
2. The fuel pump should have a bypass for the overpressure,
3. And return the unused gas to the tank.
4. Me, I'd still be more comfortable,
5. With a regulator,
6. Between the Carb and the fuel pump.
7. Don't forget to install a good fuel filter,
8. BEFORE the pump input.

I think I've got 1/2 my problem sorted.

Drove up to visit home this weekend.. and made it 20 min down the road before hte problem started

Ok.. np.. hey.. lets do a pump swap on the side of the road.. so I stuck the electric pump in there.

No change.
Well.. maybe it's because the mech pump is still in there.
bypass that and do some rigging that the Apollo 13 crew would be proud of.

No change.

Ok.. maybe coil? so I put in the one that's be scuttling around the back of my jeep since the TFI upgrade.

No change.

Now Im pissed..

so I pull the fuel filter.

No change.

Going to buy a Ignition Module... $280!!!! WTF!! WTF WTF.. leave without it.. get outside. start her.. drive down the higway... hey hold on.. the problem is gone? and I didn't even do anything.

Sooo.. now I have to take it all apart peice by peice to figure out what is actually wrong with it.


Is it possible that the Ford coil overworking the ignition module caused it to miss-spark. and now that the old coil is back on, the modlue is getting a little more life?

or is it more possible that hte coil is just messed up and not working? because neither were getting hot.
