Next saga in my quest to get this 2004 4.0 running right in my 1989 Wrangler.
As you may remember, I purchased & installed the Late 80's Ford (Big Truck) type E2000 Externally Mounted Fuel pump to supply this 4.0 with the pressure it needed (like 49.2 +/- 2) per the specs........... well it put out like 75-80 & "this would blow some seals or something". The 2004 does not have a regulator at the fuel rail so I purchased & installed a 1998 Grand Cherokee Combo Filter & regulator which now puts out like 35 which I guess is OK because the motor seems to run OK. Another thing, in order to get this set up to work at all, I had to close off the fuel return completely.
The next or current problem is that the E2000 pump starts to make noise - like a straining or surgeing sound & the engine seems to flutter & even has crapped out once so I'm getting nervous!
I think the E2000 pump isn't sucking as fast as it spits out!
Since my original 4.2 was carbureted I do not have a pump in the tank!
So yesterday, I pulled a 20 gallon Plastic tank with the electric pump & sender etc out of what was when parked a running 1994 Wrangler. I figure if I have the pump that's in the tank feed the E2000 that should cure the surgeing problem. I may than buy this universal adjustable regulator to dial in the exact required spec pressure.
So just so I don't screw things up here's what I need to know:
1) There are 3 wires going to the pump or top of the tank - where do they go? Which is Hot etc.?
A) Black which is a Ground
B) Orange which goes to a connector than is broken spliced etc......
c) Tan which turns to Blue at this connector
There are 2 fuel lines at the pump (which is not round but rectangular & held in with screws) - How do I tell which of the two is the supply line & the other must than be a return line correct?Any Help is apprechiated
