fuel pick up

[chopthebass]

I have an in tank fuel pump but the fuel pick up has no holes to feed the pump wires. Is it simply a case of drilling holes? Can anyone advise? Do I need a different fuel pick up to the suppled FFR one?

Thanks
Ian

Hi Ian,

I'm not sure about your description of the "fuel pickup". If you are referring to the fuel pump assembly (3 inch diameter flange with fuel delivery and return connections and electrical plug female OEM usually red along with the bracket that holds the fuel pump and pump sock on the other side of the flange) then you don't need holes. You should refer to the pump installation instructions. You will attach the pump electrodes to the red and black wire hanging inside the assembly. Sometimes you have to install new end connectors to match the pump. The electrical input for the pump is supplied by the matching harness connector that mates to the female connector on the top of the fuel pump assembly. If you don't have a fuel pump assembly like I described, you may not have the correct part for a EFI setup. You can post a pic to verify the component you described in the first post.

WEK.

Your pickup should look like this. See the red and black wires leading from the pump to the white harness connector on the top.

Thank you guys. Yes we are talking about the correct part Skull. Mine doesn't have electrical connections on the top, so can't go with an internal pump I reckon, unless I change it.

The Breeze product says its good for 440 flywheel hp, so that's not enough. What do you guys do when you have more HP?

The easiest option is an external fuel pump, like Holley or Aeromotive.

Depending on the tank you have, there might be an option for dual pumps.

I think I'd prefer an external pump. Can I use the supplied fuel pickup with that idea? Mine has 3/8 and 1/4 external diameter connections.

It sounds like you are talking about the fuel pickup for a carb (or EFI with an external pump) so to use it you will need a fuel pump. If you go with an internal pump (like the Breeze photo) all you will need to do is hook up the wires, pressure and return lines. You can buy higher capacity in-tank fuel pump assemblies from many suppliers.

Mark sells a 190 LPH and 255 LPH in-tank pump as well. Not just the one referenced. Internal vs. external pump has pro's and con's both ways. But internal pumps are typically quieter and are cooled so may last longer. External pumps are certainly easier to service. I will be installing an internal pump on my new upcoming Mk4 build.

[chopthebass]

Thanks Ed. So I just need confirmation that if I go for an external pump, can I use the standard fuel pickup that FFR supply? I like the sound of the 255 LPH product that Mark sells, so if it gets too complicated maybe that is the route I should go!

I think I have a spare fuel pick up with the wires if you want it.

Good Luck

Thanks Norm!!. Would this be like the Breeze one including the pump? Or would I need to add pump?

[Norm B]

It is the stock one out of a 95 Mustang V6, I think, and might be too small for your application. Sounds like you are going to be making lots of power and the lines out of the pickup don't look big enough for that. Your best bet might be to use your current one and a good external pump. Easier to repair and much more powerful than anything that can be fitted to the pick up I have. Let me know if you still want it and I'll try and find it. Garage is a mess as I've started a new project with my son. Putting a 4.5 litre Q45 engine in a 1990 300zx. Wife is going to kill me soon!

Good Luck

Ian,

I was checking my Ford Racing Parts Catalog about the fuel pump delivery. It says that a 255 l/hr in tank pump will support up to 700 hp (I'm assuming they are talking about Ford Racing pumps). So it would make sense to go with that setup. If you need more you could piggy back an inline pump for more delivery. There are some great facts about the fuel delivery systems for Ford engines in these catalogs. Remember the system needs to be balanced so you get good pressure and large enough lines and fuel rails to insure the volume is there all the way through the power curve.

Good luck,

WEK.

Thanks Wek. I have upsized my fuel lines to 1/2 inch and 3/8 return. I managed to find a complete fuel pick up, including 340 l/hr pump and AN fittings welded to pipes. I think the issue is solved now.

[CraigS]

Out of curiosity pls tell us about this engine you are planning on. Also can you put some car details in your signature line. That helps us answer questions w/ more precision. IE; I just picked the first pickup I came across in the Breeze listings. If I had known you are planning a huge motor I would have looked at gph numbers.

[chopthebass]

Craig, you are right - I ought to put down my planned specs. No its not a huge motor, just I read in another build guide (David Smith?) that the supplied fuel lines are only good for 300hp, so once upgrading those, I had to upgrade pump too. One thing led to another!

The engine is a 351W stroked to 427, EFi, and the estimated horsepower is 580 (fly/w)

Your 1/2" fuel and 3/8" return lines are way over kill for the fuel your engine will need. There are a lot of online fuel line sizing programs that can give you the answer on what is required for your engine. I'm running a 400 HP Coyote and the 5/16" fuel and 1/4" return are very adequate. The smaller lines are easier to manage and the bends can be smaller. Google "fuel line sizing calculator" for a bunch. Here is one (https://www.lmengines.com/fuel-line-calculators/)

I have been guided by my engine builder.

Hi Ian,

BTW: what monster are you building to need all that gas?

I have read elsewhere that 1/2" is good for up to approx 800 hp.

Be careful about believing everything you read on the internet (of course you just read my comment on the internet so take that for what it's worth ;))

220 liter/hr is 50 gallons/hr... draining a 16 gal tank in ~20 minutes. that's a lot of fuel!

ha ha! I read that in D. Brain Smith's build book. He was given that info by Jesse Powell at Aeromotive. He advised him that for a 500hp engine 3/8 lines are ok, but he recommends 1/2 inch. My engine builder agreed with this, so good enough for me!
