Facet electric fuel pump?

[originalowner]

Usually with a Carter you will run a pressure regulator, though there are people here that aren't and I don't get how they don't have that same issue.

My general assumption is that the factory pump may just be worn enough to lower the output pressure to something the Weber is fine with.

I know everything I've read about Weber carbs as they relate to line pressure is: They are very very picky and even a tiny bit too much pressure will cause issues.

I have a 38/38 and it was suggested perhaps I get a fuel cutoff solenoid off of EBay as mine likes to do the same. I believe it replaces the main jet.

I was wondering the same thing. That has been the "source of my confusion" so to speak.

If a Carter outputs 4-6 psi and the factory mechanical provides even less pressure and folks say they run a Carter w/o a regulator...wait...WUT?!?!?!?!?

Those factory components are incredibly durable if my pump has 345K on it and is still pumping it's ass off to beat the band is all I can say.

I have read many posts by somebody (Pennyman?) that say a pressure reg will burn up the mechanical pump in short order.

Why won't it do that with an electrical pump then?

I was a auto dealer service writer by trade- 20+ years- so I know just enough to get me in trouble. LOL

I have concluded what I have to do. Now that I have gathered all the practical info you guys have given me regarding this, and considering the symptoms, it's obvious what still needs to be done.

I was actually on the right track, as the thread title indicates. I was heading towards an electric pump install when I discovered I had a "counterfeit" Weber. Well that's fixed now. I have a Spanish made Weber sitting on the motor now. It is the most beautiful thing I have ever seen. Practically gives me a woody. HAHAHA

I am going to install a Carter P4070 in conjunction with a Holly 12-804 fuel pressure regulator so that I can limit the line pressure to 2 psi. This is what I learned as part of my learning curve from Jim Inglese, the Weber guru that builds and sells Weber carb setups for Cobra engines. (See link above.) This is the regulator he recommends. If it's good enough for him, it should be good enough for me.

All my symptoms point to Pennyman being right in that the factory mechanical pump is "over-pressurizing" the needle and seat and bleeding raw hot gas into the intake which in turn causes the run-on. In fact, if you watch the motor run from the driver seat with a clear view of the tach, you can practically tell the moment when the motor is being flooded with gas- not to mention the gas mileage is awful. I think I got around 10MPG on the last tank. I should be getting mid-teens in town. Never known as a thrifty motor, the 2.6 should still get around 15 MPG in town. Not earth shattering to be sure, but still better than 10. That really sucks on a vehicle that would be hard pressed to break 20 seconds in the quarter mile. Bwahahahaha.

I have a helping hand here local that can assist me or finish up my rough-in installs of those two components.

The fellow I'm talking about is a Master Ford Gas and diesel dealer tech who started his career on Mitsus who actually did the PDI or dealer prep on my truck for the sales lot when Ol' Reliable was brand new. Yes, the fellow that did the PDI on my truck still works on it when the repair is over my head or the job needs a lift to complete.

No, it's not done yet to my satisfaction, but I know exactly what parts I need...where to mount them...the dos and dont's...etc.

Many thanks to all who have very generous with their experiential knowledge and overall "gearheadedness" LOL

I especially want to thank MoparJA, Pennyman and Acuta73 because their posts were critical pieces of the puzzle that was being put together in my mind.

When I'm done with installing those two components (plus an oil pressure cut off switch) then I can proceed with fine tuning, jetting, etc. No point in doing that stuff until the fuel system has been sorted.

At that point, I will then have the best, smoothest running 2.6 on the planet.

*high fives all around*

I meant to thank Fordubishi also. He was the one who gave me insight to the "overpressurizing" the needle and seat.
