Correct you are. Don't know why I had 205 in my head. I installed a Duralast 15359 which is a 192F thermostat, according to AutoZone.Stuka wrote:1: What electric fans are you using?

Isn't the factory thermostat 195?
The exhaust runs between the driveshaft and passenger-side frame. The fuel line runs along the tank, then over to the driver-side firewall and up over the bellhousing to the fuel rail on the drivers side.Stuka wrote: 2: The dash gauge is known for being off. I have seen mine go down below 10, and then other times show 25 or so. An aftermarket gauge is the only way to know for sure.
3: I have never had this happen on any of mine. Does the exhaust run near the tank? How are the fuel lines routed over the engine?
Sounds likely. I wonder if that grounding issue could be caused by high pressure in the tank?Stuka wrote: 4: This sounds like a grounding issue.
I'll read through that. Thanks.letank wrote:#2 solution

I had the same issue with the oil pressure being like more a slow pendulum. Trouble free for the last year, 1200 to 1600 miles, but the trips are long distance drive of over 3hrs, freeways and hill climb and slow dirt roads
I doubt I still have a charcoal canister. EFI and no snorkel. If it still exists, it's been moved - as it is most certainly not in the location shown in the TSM.letank wrote: #3, you can disconnect the tank vent hose at the charcoal canister for diagnostic purpose, and see if the whooosh is stopped or reduced - IIRC Year 77 is still a simple canister without feedback for the PCV valve.
It has a pair of SPAL 11" VA09-AP8/C-27A fans that are rated at 755 CFM by the mfr. Is that a cheaper one?Stuka wrote:1: What electric fans are you using?

Agreed - I can't get ANY gas into my tank without inverting the filler nozzle, if it flowing faster than a trickle.1979bettywhite wrote:I agree on the 12 o'clock/upside down position of modern day gas pumps. I have no problem with venting during fill if I do this. Any other angle causes the auto shut off almost immediately.
I am very envious of the cleanliness of your undercarriage sir. Your Jeep that is. Half my time spent under the Chief these days is wiping off both new and old fluids to try and determine where leaks are coming from, lol. "oh wow, that t'case is actually silver?"
I forgot how the 77 is plumbed, but on the 74 the rubber vent line goes up the inner fender well like yours and connect to a metal pipe that exit to the wheel well, and return to the top of the gas tank where is hooks up with a rubber hose to the top metal vent on the side the gas tank.merrill77 wrote: I re-read the fuel diagram and took a closer look at my rear fenderwell where it passes through. I discovered I had not read it correctly before - the fuel tank vent goes out of the tank, into the fenderwell, into the inner fender and then attaches to the filler. However, my line is kinked where it exits the filler. I think this is why I'm having trouble filling the tank. I'm going to leave the interior panel off and make sure that hose is not kinked, next time I fill, to see if I get better results.

I hope that I have done the ammeter bypass? those powerful fans use a lot of wattage. Remember that most Grand Cherokee folks are reverting from Efans to mechanical because the overheating makes their valve seat to drop and fubar the engine which is aluminum -the GM Vega is back-merrill77 wrote:I'm not carbureted - Edelbrock MPFI.
But I will try upgrading to a higher capacity fan. It looks like there are some from the same brand that will match the existing mounts and more than double the flow rate.
