fuel pump ideas for a ls1

[younggi]

basically I'm building a ls1 260z and have run into the problem of how to make a fuel pump system work for it .

i would like to try and keep the standard tank look but was wanting to see what other people were doing.

Have a look at what NZeder has done doing , I reckon its FAB and have gone the same way. http://www.viczcar.com/forum/index.php?topic=3490.105

 

Brand new BF/BF Falcon modules $99 !!! http://www.ebay.com.au/itm/FORD-FALCON-BA-BF-WAGON-6CYL-4-0L-FUEL-PUMP-ASSEMBLY-/190492873154?pt=AU_Car_Parts_Accessories&hash=item2c5a4291c2

 

In tank solution, built in swirl pot, with sender, quiet and can upgared top better pump easily.

My setup has an external lift and EFI fuel pump from a VL and surge tank all mounted off a bracket in front of the fuel tank. It's a bit of a plumbing nightmare and would like to eventually modify the fuel tank to just have a fuel pump on the outside and that's it. What I like with everything on the outside is when it comes time for fault finding, things can be accessed easily.

Right from the word go I wanted dual exhaust to complement my LS1 so I've removed the spare wheel well and plan a non-standard fuel tank - the drawing is with the fabricator and it should be made this week. The other consideration I have is wanting as many off-the-shelf Holden (GM) bits as I can so there will be few dramas finding replacement parts. So, I made up an adaptor for the new tank which will allow me to use the original LS1 in-tank pump.

 

If you still want to use the Datsun tank then you might want to consider welding in the section of a Holden tank which mounts the fuel pump (see photos)

The GM and Ford modules are pretty well the same except the Ford mounts with studs rather than the retainer ring of the GM....I reckon this makes the Ford option more attractive.

 

The wagon module also has the fuel sender incorporated so its easy to use an aftermarket fuel gauge.

As pointed out by katokid - I did this

http://www.viczcar.com/forum/index.php/topic,3490.msg81048.html#msg81048

and I was thinking about the GM version - however when looking at their modules for use in the stock Z tank the models with the level sender was pointing in the wrong direction and they are taller - maybe too tall.

 

I went with the BA Falcon wagon item as, already pointed out by David, it bolts up ie not using a special locking ring setup - can be fabricated up without getting the top of steel holden tank (most are plastic these days). And the sender faces opposite to the in/out/vent lines making the install cleaner IMHO in the Stock tank.

 

I picked up some earl fittings to take the GM/Ford push connects to AN6 fittings. After the tank was modified I used some POR15 tank sealer kit to coat the inside and stop any rust

 

Another reason I went with the Ford Wagon item was for the sender - I am using a speedhut fuel gauge and these sender units have more common ohm used these days - not like the zed item. If however you stick with a zed sender then a stock BA/BF sedan pump should work if the height works out - they are lower than the wagon unit - however the wagon unit does need to be compressed a bit to fit my tank - and I have the later 260z which does have a different tank to the 240z (just use the old rule - measure twice, or more, cut once)

The others are right and that is the way things are trending these days but if you want to keep your tank in place and the costs down, there is simpler ways.

 

You'll need a lift pump (hi volume, low pressure) to go straight out of the tank where your current pump would be. That will pump into a surge tank. From the surge tank you'll need a high pressure pump. Something like a Bosch 044 would be heaps. From here there are a few options. You can have your fuel reg straight off the pump so it recircs straight back into the surge tank and only have one fuel line travelling towards the engine which connects to the fuel rail with no return. That would be the simplest way. If you want to here about all the other options let me know. Have a look at my build thread, there should be some pics in there.

Good luck

I went the way of buying a daewoo fuel tank cuttting out the mount section from tank I then had my 240z tank steam cleaned inside then cut hole a littler smaller than section i cut from daewoo tank welded that to my 240z tank

Then used swirl pot from daewoo tank to base of my fuel tank for fuel pump to fit in Fitted walboro internal fuel pump to daewoo mount and bolted it in

I like idea of fuel pump intank as i was sick of listening to the old holley blue with old engine

thanks heaps guys

i had been looking for options for a while but was getting no where. so this info is great i like NZders fuel tank options so i think i will look into that route for the moment .

ist crazy how much you all have looked into or modify zeds i really should get to a gathering sum time
