I am installing 1980 Stromberg carbs on 1981 efi tr7(long story). Any suggestions as to installing low pressure elect. fuel pump to replace the high pressure Bosch.
Gary

Yes, I have used for the past three years a Carter electric pump and a fuel pressure regulator set at 1 1/2 lbs. It has given sterling service and the slight whine at idle is a reassuring constant all is well with the fuel system.

Here is the link to my article.

I have a low pressure Carter you can buy cheap

Try to find SUs - SO much better than ghastly Strombergs........

Mildred,
Thanks for the info. Since the electric fuel pump for the efi is mounted on the bulkhead next to to the fuel tank, would this be a good place to mount a low pressure pump when I get one?
Gary (just turned 73)

Yes. Just as long as the pump is lower than the gas tank so gravity can drain the fuel into the pump.

Remember, the pumps we use these days are referred to as 'pusher pumps'. They are designed to push the fuel up stream to the carburetors or injection system. The old 'puller pumps' that operated with a suction bellows could be mounted anywhere as the pump would pull the fuel from wherever the gas tank was.

I really liked the bellows pumps but they cannot cope with modern alcohol laced fuels as the pump diaphragm soon turns into a wafer of goo. The internal capacitor is renown for being weak and virtually unobtainable for replacement. So, after lots of tinkering it became a lost cause to be tossed into the garbage can and hauled off.

Having to locate the pump next to the gas tank will one day prove to be a difficult chore as it will most likely occur on a cold rainy night on the side of the road. There we will be. On our backs with a failing flashlight trying to replace the pump with gasoline running down into our armpits and splashing on our bifocals. Were it a bellows pump, the only moisture to deal with would be the cold rain drippng down our collars.

These are the psychic nightmares I have.

Mildred,
Thanks for the great response. Another concern that I have is the automatic choke, which appears to be controlled by water and having two wires attached, I assume electric also. Does anyone have any suggestions as what kind of manual choke is available and where can I get one?
Gary

Before you start to dismantle the water choke setup, please avail yourself of the truly excellent article by our own Steve of Wichita Falls, Texas. He, too, was plagued by a recalcitrant water choke or, FASD, and composed an article to resurrect them. The article should be found using the SEARCH function at the top right of your screen.

As my 1976 model car has the factory manual chokes, I am not familiar with the FASD. However, if it is possible to fix yours, you will be better off doing so rather than, to be somewhat vulgar, 'buggering' together the rather cheesy manual choke conversion foisted on the public by our prairie pals at V-B.

It has always been my fate to have to re-engineer all my modifications to whatever device being dealt with. It is never cheap, easy, and always takes far more time to complete than just simply fixing what's there. That said, my machine shed tinkerings have generally turned out well, tho there have been a few spectacular and expensive failures along the way.

Gary - this isn't my old TR7, is it?

I finally got back to installing the AZ carbs, but having problem getting nuts started on the bottom middle studs. I am wondering if I am using the correct sequence. I have mounted everything to the intake (the carbs being last), but can't get my fingers in there to start the nuts. What am I doing wrong?
