Help, need to find more stuff for EFI swap.

[66P51GT]

I pulled this image off of one of the supporting links from Håkan's site.

Doen't this look like a modified external oil filter adapter?

I'm also thinking about using the EFI stuff I have laying around. My thoughts on how to mount everything was to turn the area right behind the back seats into a 'command center' (quoting GP). There I'd put the batt in the middle, then the solonoid, the fuse box and the computer. All mounting either in it's own box, or on it's own little bracket.

The more I think about it, the more I'm convinced that I will be doing the same. Wiring everything to the back of the car, where it is centrallized and easily accessible seems the best plan.

Oops I wrote that incorrectly. The pump is fine, you just need to use the front sump pickup.

Can I use my early-model timing chain cover (which already has the dipstick hole) with the reverse flow waterpump?

 

[88 Fox GT]

Glen's 1965 5.0, how do you have your auxilary fuel pump hooked up? Toggle switch or what?

Can I SAFELY make a header tank out of steel?

And does anyone know if I can use an early-model timing chain cover with the reverse flow water pump?

 

[88 Fox GT]

I have been wondering, could I just make my own "reserve tank" with all of the necessary plumbing? For instance, a small metal tank that just holds fuel. An auxilary pump would feed the fuel to it, and an inline high pressure pump would take the fuel out of it and to the engine. What do you think?

I believe that's the basic idea behind the header tank. I guess we can't go wrong if we do something like Hakan and Ultrastang did with their's.

The whole harness wiring issue looks pretty simple to me. But making sure I put together a solid, reliable fuel system is my biggest concern.

 

[88 Fox GT]

I know what you mean. That's why I have so many quesions. I just want a safe and very reliable fuel system.

Ok, I know a guy with a tig welder. I am thinking I may go with the in-tank pump also. I need to know some dimensions, if you guys have them. Thanks.

 

[88 Fox GT]

Glen's 1965 5.0, I have taken the picture of your header tank and added captions of what I THINK is what. Please tell me if I am correct and tell me what the other line is that I am not sure about. Thanks.

 

[Håkan]

Where you have written "What is this for?" you can see the connection/fitting for the return line from the engine. The rest of your assumptions are correct as far as I know. Hopefully Glen will jump in and correct me if I am wrong.

Both my fuel pumps are connected to the same curcuit, that gets 12V through the fuel pump relay when the ignition is turned on, both are also connected to an inertia switch which I strongly recommend.

I had a small leak in one of my lines and seen what kind of pressure the high pressure pump puts out and that´s why my recommendation to use an inertia switch.

The first header tank that I made and that´s pictured at my website was made out of steel/sheetmetal and soldered, a friend of mine that´s a plumber helped me to solder it. Since that I´ve made a new integrated TIG welded header tank in a new crossmember I have for my rear suspension. I don´t know the exact dimensions, but we are talking about something like 2 qts.

 

[88 Fox GT]

Thanks Håkan. But, where does the return line from the engine come from?

 

[Glen's 1965 5.0]

Håkan is correct on the fitting issue. I use the original fuel line as my return line and it has worked without a flaw.

Both pumps are on the feed from the inertia switch. The low volume pump draws very little current.

 

[71vert-pga]

Reserve Tank.

Speed Demon,

I think this might be exactly what you mentioned earlier. Same idea, just no in-tank pump. This one's made from a small section of exhaust tubing. Low pressure auxiliary pump feeds it. High pressure in-line pump going to engine.

[Glen's 1965 5.0]

Interesting but it appears that the surge tank will need to be mounted above the HP pump so the HP pump will be able to draw the fuel when needed. I have pondered the tube setup before but threading a renovable cap so a pump could be inserted and removed kinda had me stumped.

 

[88 Fox GT]

Ok, project is officially underway. Tonight I took off the hood and hinges to prep for the remove of the engine and tranny. I also drained the tank and removed the old fuel line, man was that thing a POS. Not sure what I am going to do next. I have been trying to get a hold of the guy who has the EFI engine, but he wasn't ansewering his phone and hasn't responded to my message. Hopefully, we will start pulling the engine tomorrow. I really hope to get it out of his car by this weekend. If not, I am going to go ahead and pull mine out. Got lot's of stuff to do!

 

[71vert-pga]

You might use the old fuel line as the return-line.

 

[88 Fox GT]

I have one peice of new fuel line that I ran from the old line and plumbed through the engine compartment to the pump, so I could probably use that. Or buy a new peice of line.

Cuting and extending the 61 pin harness from the engine compartment to the trunk will be a hassle. Mount your Computer underneath the dash, then run power as necessary to there.

There are a lot of intricate and well designed solutions in this thread for efi conversions of an early mustang. Turning this around in my head, I think either adding baffles to my existing tank or making an external tank is beyond my current fabrication skills. I wouldn't be confident that I could make something that wouldn't leak later.

As stated several times in the thread, external pumps can be noisy. So..

The question that occurs to me is: aren't there any tanks out of a modern car that will fit in an early Mustang? It seems to me that this would be a lot simpler way to solve the problem.
