I need suggestions on what efi fuel pump and filter to use. I'd like to run only one fuel pump and an easy to service fuel filter that can also be a small reservoir for the fuel pump. thank for any info

 

I am using a Carter P74028 high pressure pump and a Hastings GF115 fuel filter ('86 Mustang), with stock Ford fuel line connectors. I am running a pusher pump (Carter P4594) to pull fuel from the tanks to feed the high pressure pump. I had trouble finding a high pressure pump that could do it by itself. You could always opt for an in tank pump, but it can be somewhat expensive.

With the factory style fuel hose connectors, I can change the filter in under 5 mins. The pump would take a little longer as it involves disassembling a clamp to remove it. But it is still very serviceable.

BC Broncos has a EFI fuel system accumulator that acts as a fuel reservoir.
It's set up to allow the engine to run for some time if the tank pickup becomes uncovered. A normal EFI filter doesn't have the capacity to do this.
I have one for mine but I haven't been able to install it yet. I have heard good feedback from a few people who have though.

Jason, Is the stock ford fuel line your using the black plastic hard line? If so, can you tell me where on-line to purchase it by the foot? I have the slip on connectors with the duck-bill clip (I think thats what its called). Originally I was going to use the fuel pump from an E350 and an aux. pusher pump with a res. filter from fram but I was unable to find hard lines to run from pump to rails then return back to tank. The s.s lines with AN fitting are great but kind of $$$. thanks for the input

 

My fuel system is pretty cheap compared to some of the high dollar systems I've seen. It isn't shiny polished or fancy, but it is very functional and it doesn't look bad.

I used Parker Push Loc 3/8" hydraulic hose for the supply. I have a 23 gal fuel tank, has a small section of 3/8" to a universal fuel filter, and then out to an electric tank switch valve (I'd planned on using the second tank originally)and then to the pusher pump which is mounted on the pass side inner frame just forward of the fuel tank. The fittings on this pump are barbed. From there, it goes into the high pressure pump. At this point, I used EFI hose clamps and the formentioned duck bill clip connectors. After trying to salvage the connectors from my donor car, I ended up finding some Ford part numbers for just the connectors. I clamped the hose tight on the connectors as they are 5/16".
I have a 1 ft section of push loc between the pump and the EFI filter that also has 2 duck bill connectors. My fuel filter mount puts the filter above frame level so I routed the hoses to the top of the frame to keep them away from the headers. It runs up to the front of the engine. I cut the original spring lock couplers (supply and return) off of the plastic hose on the donor car. And I cut the lower section of the engine side (stainless hard line). I clamped the frame side coupler to the 3/8" push loc for a flexible connection.
Since the OD of the engine hard line was nearly 5/16", I EFI clamped 2 short sections of 5/16" fuel injection hose to both ends of the engine hard line. I secured both hard lines together so that they would not rub. For the return, I ran 5/16" EFI hose (high quality, doesn't break down as easily to heat), back to where the supply hose routes to the top of the frame. It drops down and attaches to a 5/16" steel line that is wire clamped to the frame. The hard line goes back and turns into rubber hose again where it hooks up to the return side of the tank switch valve.

Duck bill connectors from Ford: not sure if they're still available

5/16" straight connector N806187-S190
5/16" 90* connector N806186-S190

3/8" Parker Push Loc, should be able to find easily from any hyd supplier or truck parts supplier

5/16" fuel injection hose NAPA, a little expensive but worth it over the cheap stuff
EFI hose clamps, NAPA do not have slots in them for worm drive, can tighten more than a standard clamp without cutting into hose

They do make the duck bill connectors with a section of plastic hose for repairs, but I have found that it is difficult to work with.

I have a few pictures of my fuel system if you're interested.

Yes please especially on your fuel pump set up and on your connection to your fuel rail.
sorry for the trouble. as always thanks again
Mike

 

No trouble at all. I will take some pictures of it tomorrow.

Jason

 

Go to my profile and then to my gallery. I have pictures and some comments posted there. If you have any questions, let me know.

Jason

 

wow,those are great pictures! I had a hard time visualizing the whole scene. The pictures really clears up a lot of my confusion (typical carb guy). I see that hose clamping efi hoses to the duck bill connector can be done! that save me alot of $$$.
I'll be following your set up as I know its been proven to work. I think alot of others will be using your pictures for reference in the near future. thank so much Jason.
Mike

 

Jason, as I gather my funds and my parts together to follow your set-up. I'm wondering if you think this set-up would work for bench testing only. Could I run from the existing stock carb fuel pump to an old efi pump/filter mounted to fender, then to fuel rail, then a long temporary return line back to the filler hose? Do you think the stock mechanical fuel pump would be enough gpm for the efi pump? I just wanna test this the circuit out to see if it runs and do a few self-tests.

 

I've heard this question a few times over the years, but I don't know anyone that has actually tried it to tell you that it works or not.
I'm not sure if the stock mechanical pump will supply enough volume to feed the high pressure pump. But since you're just doing it for testing purposes, give it a try.

Jason, I need to ask one more thing on this topic. Are you running the pusher pump on
the same f/p relay as the hi-pressure pump or is it on a seperate f/p relay?
thanks

 

Right now, it is on the same circuit and it has worked ok that way. But, I think I am going to change it and run a separate relay controlled by the existing fuel pump relay to supply the low pressure pump.

Jason

 

(I think I am going to change it and run a separate relay controlled by the existing fuel pump relay to supply the low pressure pump.)

Jason, were you going to trigger the push/pump relay from the out put side of the hi-p relay terminal?, or from the terminal that the ecu grounds? I also found an unused A/C relay on my wire harness. Can I use it for the pusher pump (carter p4594)? thanks
mike

 

I will probably trigger from the output side of the relay (12V) going to the high pressure pump. You could use the ECM ground as the trigger if you wanted.
You should be able to use the A/C relay as long as you can decipher which pins to use (Should be pretty easy with a multimeter). I use universal 30 amp Bosch relays because I have a bunch of them and they are easy to find at any parts store when I run out.
