HOW TO: fit a walbro/ebay intank fuel pump

[Dave_IOW]

Eventually got it 5 mins after that message lol.

Put rubber over pump and get half way in there, then there's a bit where the pump isnt completely cylindrical which gives you abit of room.

Put the rubber on, and slam that pump in! 

Job done!

am i right in saying, if i was to get an uprated pump+swirl pot from an lcr, i'd only have to get up to step 7? ie, take current swirl pot out, disconnect plug and 2 hoses. put lcr pot in, connect plug and 2 hoses? and possible new o rings etc.

[Dave_IOW]

Indeed. Straight swap.

nice one

a lot less steps

Interesting guide, I like it.

One question though.....

Does anyone know exactly how much fuel comes back through the fuel return line? and does the return just pour back into the main tank, or directly into the swirl pot?

reason I ask, is that in my track car I'm flat out for much longer periods than you'd ever be in a road car, and with my injectors running near flat out at 350bhp I'd worry that the combination of a 4mm hole and the fuel return line wouldn't keep up with flow enough, considering the main lines are I think 8mm dia.

What stops the swirl pot from being emptied faster than it can fill?

I would guess it would be dependent on how your driving the car, piddling round town you would get a return but im sure at near flat out at 350bhp there is not going to alot of fuel returning.

Maybe use one of the uprated fuel rails that doesnt have the return? 

[jonrandom]

Ok by reading some google stuff dont think we can run a non-return fuel rail, well not with out alot of pointless work.

Prawn I'm sure you would be best having a external swirl pot.
Usin you original pump as a low pressure pump To fill the swirl pot (1L or so) with a return to the tank.
Then use a walbro inline pump to pump from the bottom of the swirl pot o the fuel rail and return to the top of the swirl pot

Bit like this...

just to update on this, i do currently get a bit of fuel starvation when low on fuel (only when im just about to touch the red and going round roundabouts below 1/4 tank). it may need a bigger hole than 4mm as prawny suggested that the fuel lines are 8mm and pressureised, something i didnt think of.. or it may just be a sh!t design.. i will experiment with the size of the hole and report back
