EFI fuel tank.

I know a few guys out there are running fuel injection on the moggies but just wondering if anyone had managed to fit an efi pump to the standard moggy (traveller in particular) tank?? I am not against running external pumps but just thought maybe i would ask.
cheers,michael.

The trouble with using the original tank is one the capacity, there is no provision for a return pipe, there is no swirl pot , and there are no internal baffles. There is only one company offering a 9.5 gallon bespoke easy fit tank which offers all of these plus a drain plug,extra breathing tubes for anti splash back and ease of install. If you do not go for an internal swirl pot then you will need to double up on pumps as you need a low pressure feed to the pot then a filter then a high pressure fuel injection pump, fitting all of this in is a bit of a challenge.

ok so I am making a subtle guess of which company makes them...........Nice one, will have a look at the website of guessed company. I am not against an external swirl pot and 2 pumps but I already have an intank efi pump capeable of supplying 280 hp so it almost makes sense to buy a proper tank.
thanks Jonathan. As always it is nice to have a well balanced forum that doesnt completely freak out when someone mentions modification.
cheers,michael.

So would the aforementioned 9.5 gallon tank accept an internal F.I. fuel pump, eliminate the need for an external swirl pot and if so which fuel pump would you recommend?

We could add a suitable internal pump at the time of manufacture, but for ease of maintenance and different applications we do not normally do this.
The tanks are fully baffled with return feed, internal initial filtering drain plug,additional breather pipes and an internal swirl pot.
The pumps we use are Sytec units chosen individually for their suitability to the injection demands of the motor.

Okay, is the larger tank you fitted to my car as described above minus the pump (E.g. inc baffles and swirl pot) and how difficult is it to retro-fit the pump?

Darren your tank is the ordinary 9.5 gallon version I think. Does it have a return pipe. If not then it has no swirl pot or baffles as these were only fitted on our re designed/spec'd tanks from late 06 onwards. As the tanks are fusion welded togeter it might be easier to just buy a new version. I will ask about internal pumps next time I'm down at the plant. My opinion is that its better to have external pumps and filters just incase of failure, or just regular maintenance.
You may wish if opting for the new tank to wait a few months for our low level big tank which allows the fitting of a wheel above it as in normal minors. Capacity is only slightly lower than the injection type.

Ok cheers Jonathon. The tank does have a blanked off return. I think there was some sort of baffling as I could feel it with the fuel float when I changed the gasket a while back.

Ahha, that'll be the swirl pot then, baffles came in only at the end of last year.

What the issue with simply running a low power pump from your fuel tank, into a baked beans* tin and then having a high pressure pump coming off that. Plenty of space in the boot well for this setup.
Voila - external swirl pot and no need to spend a lot on a new tank.

(*ok, maybe not a bean tin but you get the idea)

I think that maybe when costing up, a swirl pot additional pump filter,piprwork,brackets etc it may be just as expensive as a new large capacity tank. Cannot speak for Darren and his particular application, but probablt it is a space issue.

This is all pretty useful - I'm looking at pressure regulators that go with the Metro turbo and note that they have a return pipe. I need to read up on fuel supply pressure and rate...

I'll have to get prices of the new tanks from the company concerned, to go with the other information I have from them.
