What do you all think of this location for mounting my new pump in the front?

Besides space, I have some other goals:

1. Avoiding mounting on any sheet metal shared with the passenger compartment.
2. As much protection as possible.
3. Short fuel line runs between the tank, filter, pump, and hard lines.
4. Access to the lines without pulling the tank.
5. Access to the pump without pulling the tank.

My proposed location probably does not satisfy goal 5 (maybe), but otherwise I like it.

I think if you take a look at the later model cars, there is a cut out of the front wall at the tank, with a stock cover that may suit your needs better.
I mounted mine in the front trunk on the passenger side to provide simple access to change filter elements.

I do know about the stock 75-76 location on the left side, but I prefer not to cut an access hole in the bulkhead. With my proposed location, I might be able to remove the pump through the existing big round hole.

Edit: That seems like a challenge (IMG:style_emoticons/default/sad.gif) .If you don't want to do the 75-76 upgrade, maybe better in the rack and pinion area to have an easy access... I am in the process of moving mine to the front and will do the 75-76 cutout. Porsche did it that way, I will use their engineering (IMG:style_emoticons/default/smile.gif). I also plan on recuperating the square filter bracket from the back of the car and move it to the stock 75-76 location per yellow car picture above.

Based upon my multiple locations, and my big hands, I could not get the pump out of that hole.
I would agree that under the car near the rack is a better choice.
Volvo had a similar pump under the p1800 and it lasts about 30 years...
I believe there is plenty of room near the rack for both the pump and a smaller inlet filter.
Put the other filter in the engine bay.

I always move them to either one of the 2 locations that the factory/dealer moved them to. Either the stock 75+ location by cutting the front bulk head on the driver side and using the factory blister/cover, or behind the steering rack cover under the car on the passenger side. The location you have it in the picture looks like it would be extremely difficult or impossible to fully access once the tank is in.

I just went through this myself. Pump is also mounted below the tank.

I was not looking forward to pulling the tank to access it either.

But once I started on the job, it was not so bad. Didn't remove the front lid, but i did scratch the paint with the tray around the filler neck. so I removed it. changed the filter when I was in there.

one man job.

I don't like the idea of beating up the steering pan tray, like I had to do when it was mounted down by the rack. Maybe that pump will fit without doing that IDK.

Could one of you guy's post a few pics for us interested in reproducing the 75-76 fuel pump access opening and plate. A measurement of the opening would be awesome. Thank you.

I found there was plenty enough room to mount pump under steering rack cover in my 73, plus 2 filters. I damaged 2 filter socks trying to install in tank, so a filter before and after the pump makes more sense to me. Also placed a filter in engine compartment before injector rail, easy access to cheap filters is better than a plugged injector. (IMG:style_emoticons/default/aktion035.gif)

Don't forget the pair of ~1" thick rubber isolators to mount the bracket to the body.

I made spacers out of truck inner tube, easy to hear the pump start when I turn the key! (IMG:style_emoticons/default/piratenanner.gif)

Thanks. I'll make the plate here, more interested in the size of the opening in the bulkhead. Never worked on a 75-76, makes perfect sense to put it there.

Moved the pump from behind the firewall to the front compartment. Sits on a shelf and has a removable plexiglass cover do nothing snags.

The opening is approximately 6.5" x 2.5" but it is best to have a 75-76 blister cover in hand to make a template. I just test mounted my pump in my retrofit opening yesterday. Pics below and here's a link to my process for cutting the opening. http://www.914world.com/bbs2/index.php?s=&...t&p=2652159

And if I were the OP, I'd do as others have suggested and put it in the steering rack area the same as the factory specified for pump relocation per recall. That's where mine was when I bought my car and it worked find in that location.

I went through this over the winter. My car is a 1970 1.7. Years ago the PO had a mechanic mount the 3 port pump up front by zip tying it to the steering rack. It was a mess.

I redid all of the fuel lines using Chris Foley's tunnel lines and his fuel pump mount. This provides great access to the filter and pump but I had a heck of a time getting the lines routed and all of this to fit without kinking the fuel line. It's working now though and I've got a few hundred miles on it.

The pic is in process. I couldn't find one with it all hooked up but this will give you an idea of what I did.
