I am going to incorporate a fuel pump system from a van to provide pressurized fuel for a project of putting a efi 5.0 into my 64 pu. I stripped the old system off the van today and got the reservoir, filter and the high pressure pump. The engine I am using is from an 89 Marquee. It only had one fuel pump and that was in the tank. no reservoir. So people have told me that I need to use a low pressure pump to suck the gas from the tank and have it ready for the high pressure pump. Is the reservoir necessary? I am adapting the gas tank behind my seat to recieve a return line.
I'd say no. As long as you are running the two pumps, it should be fine.
The low pressure pump needs to be in the tank to push the fuel out to the high pressure pump.
I am planning on putting the low pressure pump on the outside to draw the fuel out. From what I read no one has a good solution for putting a pump in the old 64 behind the seat gas tank. Thanks. Keep the ideas coming.
For my EFI conversion to my early Bronco I'm using a Carter 7 psi external fuel pump right off my tank to feed a hi-pressure fuel pump that mounts outside of my frame rail taken from a 90 E 350 van. At first I used the fuel reservoir but later replaced it with an ext. mount fuel filter. I wanted some sort of reservoir to keep enough fuel to the efi hi-press. pump while off roading on steep inclines. You can visit my gallery to see my set-up if it will help you with some ideas. If I had to do it all over again I would go with a single intank pump from a stang. Good luck
Hey this is great info. That single intank pump, is it easily converted to a tank from a 64 or would a person need to mount the tank also? What year of stang? What did you use for fuel line? As all of the line I have seen is the plastic stuff. I will check out your gallery. What year is your efi engine you put in your Bronco? What year is that? I thinnk this conversion would be pretty simple (89 5.0 into a 64) but I am chasing down all the wires so I can use oem cruise control. I welded a 77 4x4 front end under the 64 so I working disk brakes and power steering. So I have the steering wheel and column already working. Thanks.
Mine is from an 88 5.0 HO intake and 19lb injectors. It is a speed density system that I installed onto my original 74 302 engine. Pretty much everything bolts up. I'm using a cast gear to match my stock non-roller hyd cam. The ECM is from a 87 stang HO. All this is working fine and hope to swap the 88 5.0 HO engine in the future which has better comp. and a roller cam. I believe these motors have stock forged pistons.
The 87-92 stangs with the 5.0 all have the intake efi pump (I think) and will give you the required 40-45 psi to run your system. There are several aftermarket companies who supply Early Broncos EFI pump set-ups but I'm not sure how your 64s sending unit needs to be modified to mount an efi pump and strainer but I'm sure an aftermarket supplier makes one for your conversion. Try doing a search. You only need to use hi-pressue efi hose from after the hi-pressure pump up to the fuel rail but from the fuel tank, fuel filter, primary supply pump, and return lines can be standard fuel hose (much cheaper). However I did use 5/16 steel line for the return from the fuel rail back to the tank because I had a roll sitting on my shelf.
One last advice. Try to get a complete mass air system if possible. It will adapt alot better to performance add ons later. Try to get a complete system that you know was from a running vehicle. Take your time and do lots of research. Fordfuelinjection.com is a great source along with a book by C. Probst labeled Ford fuel injection. Feel free to ask any questions you might have because there are alot of quys here that really know their stuff and are really helpful as they have done for me.

Did you use the charcol canister and if not do you get a smell? I looked at your gallery and did not see one. How about the tab and tag solinoids? Do you have a check engine light hooked up? I got a high pressure pump off of a 89 van but it only had a 6 cylinder in it. Are those high pressure pumps expensive? So instead of using the standard ford clips to attach the hose to the pump and filter did you just run the hose end over the outlet or inlet and put a hose clamp on it? Is all of the line 5/16? Looks like the feeder line may be bigger.
I have been researching this for a bout a year and have asked a lot of questions to these guys on the forum. I am going to check out the book you mentioned and web site. Great!! Thanks.
The 6 cyl pump is the same as a V8 so no worries there.
I wonder if you can adapt a late 80's Crown Vic tank to fit in your truck. They sit almost vertically in the car. This would give you 1 high pressure pump without having to run two. Do you have the donor car that the engine came out of? it should be the same thing.
I can't remeber exactly what I did to the charcoal canister because its been a couple of years now. I'll have to crawl under and look but I think I left the stock charcoal canister connected to the tank and illegally allow it to vent to the atmosphere but not sure. I don't have a fuel smell issue at the moment. I'm using the original duck bill fittings to the pump and fuel filter. Carefully cut away the plastic hose and clamp the ends to hi-pressure efi rated hoses with hose clamps from BMW. The reason I used BMW hose clamps is because it doesn't have the little slits on the band which can cut the the fuel hose. This was suggested by one of the EB members. I left the TAB/TAD solenoids connected to the wiring harness but plugged the vacuum supply lines. I left the EGR functional. I do not have a CEL light connected but do my trouble codes with a cheap Acron code reader. I ignore the air by-pass trouble codes because the vehicle runs fine. Good luck.
I still have the donor car. It is an 89 grand marquee. I looked at the tank and it is vertical but probably about a foot in depth and 18" high. Was you thinking that I could put it behind my seat or try a frame mount? Mauicruza maybe I missed it but you must have modified your gas tank for the return hose. Any suggestions? How far down into the tank should the return line go?
Also do either of you know what the cruise control amp looks like? After a quick ohm check I think on the grand marquee they may look like flasher relays.
I didn't do any modification to my tank sender because my Carter pump is pulling fuel from the tank to feed the Hi-press. pump. My return line is routed to the gas filler neck vent line. It's the 3/4" hose that runs parallel to the filler pipe and up to the gas cap. Most people braze a nipple to the larger filler neck but I don't trust my welds and instead fabbed a tee and connected to the vent hose. Either way, make sure you connect as far down from the gas cap as possible.
Sorry I don't know about the cruise control.

I remember you emailing me last year about that. So you went right through the rubber line. I suppose I could do that with the charcol canister if I wanted to also.
