Thanks Carl. And yes to the block-off plate. And yes (with riders, caveats, chicken little warnings and much hand-wringing) to the cutting and inserting of the pump into the fuel line. But...
We have the block-off plates as our #8037. The pump is the #8021 and both can be seen here: https://www.wildhorses4x4.com/category/ ... =fuel+pump
For the fuel line, you likely want to replace any rubber sections if the rubber is old. And most (if not all) EB's came from the factory with at least some hard-ish plastic fuel line runs, with rubber fuel hose as the interface between the valve, original pump, and the feed line/sending unit. It's also fairly tightly run, so not a lot of slop letting you easily mount a pump without adding some additional hose.
Which you would want to do anyway, if you have two tanks and want to put the pump farther rearward like discussed. So you may need (most likely will need) some additional 5/16" or 3/8" good quality fuel line. You don't need 100psi rated EFI line, but don't go for the cheapest stuff offered at most parts stores either, as it's likely not going to last very long. Sadly just like so many of the things we get these days...
You'll need to check your own fuel line sizes to be sure too. All EB's were 5/16" between the mechanical pump and the carburetor, but many (including my '71) used 3/8" line between the tanks and the pump.
Many other people have reported finding 5/16" line under their trucks too however, so you do need to check what you have.
If you have a standard sending unit with good sock filter still in use, you probably do not need a pre-pump filter in addition to it. Just run the pump and the filter that Ford uses on the carb. But it doesn't actually hurt if you want to add a good filter either.
Too many filters can impede flow, but I don't think you're worried about that at this level. Another one of the "up to you" decisions.
Now, for the wiring...
You do not run it directly from the ignition switch or existing wire directly. You want to use a relay to make sure you get full power to the pump and do not put much additional load on the switch. Pumps like these don't actually draw that much current, but every time you add something else to the stock ignition switch you get closer and closer to it's happy-place limit.
A relay and some 14ga wire, plus an inline fuse and you're good to go. Well, almost.
With electric pumps you really do want at least a cutoff switch tied into the oil pressure so that when the engine is turned off or dies, the pump will shut off no matter what else is going on.
An inertia switch isn't a bad idea either (in fact it's a great idea) but you can keep things simple for now if you want.
Are you familiar with general wiring stuff? And relays? If not let me know and we can run through what's what and how you'd want to utilize a relay.
Relay's are just "remote switches" basically, and use very little energy themselves. You want your trigger wire to be from one of the ignition switch's "ON" circuits and not one that has juice in ACC too. This way you can still listen to the radio or do whatever you need and not have the pump running when it's not needed.
Those would be either the Green w/red wire on the passenger side for the voltage regulator, or the Red w/green wire behind the engine for the ignition. My go-to is always the regulator wire though, so nothing else is attached to the ignition system unless that's your only choice.
Let me know if you have any other questions.
And thanks for using us. You can just call it in or run through the website if you prefer. We do take PayPal if that's your preferred method, but you definitely need to either call it in and they'll put you in touch with Dave (or maybe Brian too) specifically so they can run it through, or if you purchase online just put PayPal in the notes and someone will call, or e-mail you to get the particulars.
Otherwise credit card works too.
I'm not in the office much (and won't be tomorrow) so working through the system you'll get whoever's handy at that moment. I'll be in on Saturday, but the phones don't work on weekends anyway (thank goodness!) and nobody would have time to answer them if they did. It's our Annual Bronco Roundup this Saturday and I'm going to be hanging out in the parking lot with three or four hundred of my closest friends!
Good luck. And no problem asking questions along the way. Rather than through the website here though, if you're in need of an answer sooner you can use my email@example.com
e-mail. Or if you're actually in a hurry and I don't answer right away, the phone is the quickest.
