Quick question. Had my 740 for almost 15 years and over 2 million miles( no misprint)!!!
Know absoutely everything about them besides this???
if your intank pump is dead like mine... How and where does the gasoline make its way to main pump/ injectors????
Where in the sender unit does it travel through???
Thanks fellas

 

it flows through the dead transfer pump. your main pump has to work much harder, and when your gas tank is much below about 1/3rd full, you may experience fuel starvation at high acceleration.

 

I never experienced that never. I purposely pulled intank pump at low low fuel levels many times.
absoutely no difference in performance or sound.

I do have a regina 1989 non turbo dual fuel pump system.
just putting that out there. I don't believe it travels through a dead fuel pump but rather the hole on the bottom might be wrong.
anyways ive never changed it and have well over 2 million miles. No misprint!! In my car it appears irrelevant at this point.
Peace brothas

 

where did you go .. to the moon and back a few times? lol seriously though i have no idea whether my in tank pump works or not all i know is
my 240 starts runs and gets from a to b every time in all weather .. so far...

 

Sorry you just broke the BS meter on the mileage statement.
If you do have a 2 pump Regina system which is rare and the intank pump is bad then you get the conditions that were stated above. If you think you have a 2 pump system then pull the in tank pump and test it. Come back and tell us your results.

 

Nobody believes my miles so im not sweating that.It is a regina 2 pump system!! No need to pull intank. ive pulled the fuse piles of times well into the red range and it had no effect on performance or no sound changes.
i believe the 1/3 tank info doesnt apply to my car.
and having a 2 pump system on my regina car is rare. I ve personally never seen another.
ive gotten numerous offers to sell it but no way Jose.

 

are you sure pulling fuse 11 is disabling the in-tank pump? its quite possible its not, your car is something of a muddle so its wiring may be weird, too.

shut the ignition off, remove fuse 1 and fuse 11. take a foot or so of some thin gauge solid copper wire, like AWG 22 or 24, strip about 3/4" from each end, and run this jumper wire from the bottom of fuse 1's socket (which is always hot) to the top of fuse 11's socket, this should power just the in tank pump, if you remove the gas cap, you should be able to hear it humming with your ear against the filler pipe, its easier if the fuel level is relatively low.

now move that jumper to the bottom side of the fuse 11 socket, and you should hear only the main pump run. when done, remove this jumper, and replace the fuses, 25A in fuse 1, 15A in fuse 11.

2 million miles in 30 years is 66000 miles/year, 1300 miles/week, or an average of 180 miles every single day with no downtime. assuming the vast majority of those miles are highway miles at 100km/h (60 MPH) average speed, you have spent 22 hours/week, every single week for 30 years, in the seat of your car. you've had to change your timing belt every year, oil about monthly. you are probably on your 30ths or 40th set of tires

 

Thanks for info brotha P!! Your calculations are close to right. Didnt go through that many tires though.
i checked what you said.... Another question. If you remove fuse to sender unit... Shouldnt the gauge not read fuel level????
thankyou young man

 

the fuel sender is completely independent from the fuel pump. the sender is a variable resistor thats wired up to the fuel gauge, and isn't directly powered. the gauge does provide some small power to it, which comes off the general instrument panel power circuits, and the gauge displays the current passing through the sender, which is proportional to the resistance per Ohm's Law....

 

Even if i disconnect sender unit connector, it still gives a reading on Gas gauge. And no effect on performance or noise level increase.
peace brothas

 

wow, your car is like magic. the gas gauge works without being connected, and the in tank pump isn't doing anything yet the main pump isn't ever making noise.

 

He said he only owned the car for the last 15 years so this would peg the BS meter.

 

Not his first time either...

 

Yall must be a little slow or something???? I had the car for 15 years. I'm not the original owner!!! You Dont know the previous mileage....

Its not something i broadcast like that guy with the p1800.
mileage is nothing to these cars. There is no reason to make up stuff.
my original question was pertaining to intank pumps.
Yall don't run the forum!! Half the time your information is self pleasing and innaccurate!!
peace

 

I've seen the elusive two pump Regina myself and it was discussed (with pics) on this very forum!!!

The under car main fuel pump that is pictured currently resides on my '92 240.

The in tank pump that is pictured is still in my basement.

 

I think the mileage argument can be solved easily enough with a Carfax check. Just list the VIN and we'll see...

 

I'm curious to see some pictures of this 2 million mile 740.

 

Sure. Its not a big thing no body believes it anyway.
ive been thru several odometers.

Happy holidays fellas

 

That makes sense since the odometers go only as high as 999,999 miles. Once you reach that, I believe they self destruct, right?

 

nah, they go through a wormhole in the spacetime continuum, and reset back to zero, making it a brand new car all over again!
