Hi all dont know much about the mpi/spi tanks so go easy on me lol

want to use it for my turbomini as it has the return on it but dont think the internal pump will have enough pressure?? I already have the common type of external electric fuel pump that came with my engine, and if i do need to use my external fule pump is there a write up on how to convert the internal to be a pickup only?

Thanks everyone *happy*

SPI is fine for 8-10 psi, MPi is find for fook loads of boost.

The SPI pump gives about 1 bar of pressure so will do for about 10psi of boost, the MPI pump is about 3 bar iirc so will be fine for 30 odd psi of boost.

you can replace the spi ones with a pump from something like a puma or some hondas etc.

join the wires inside the tank, bit of hose to join the new pump to the existing plumbing

The link I gave you is a kit everything you need is in there, the mod you have to do with that kit, shorten the feed pipe about 1/2", and the carrier, cut a piece out so you can sit the pump in, then use a plastic tie to hold it in place, job done, got my tank off at the moment trying to suss the smell of petrol in boot, if I decide to take out the pump again while sussing the smell Ill post a picture..

Cool pics are always good, what are the seals like for resealing?? Or do they always need replacing?

Just swapped my spi tank over to an mpi pump the other day, one thing i noticed which bugs me is the fact the spi pump pulled off the feed pipe tightly, but once taken off, neither the spi or mpi pumps seal as tightly as the spi once did, so i reckon its gonna just piss fuel out around the pipe under pressure...

You wont get that with the kit I fitted because the pump is connected via a piece of rubber pipe and two jubilee clips..

I doubt if my pump is still ok.
Since it's a spi pump i just ordered the one from the link of .bay.
A simple swap and one more job sorted.
God i love this forum*happy*

there is nothing wrong with a A-series that a turbo can't fix.

The thing about it being loose on the connection to the pipe I'm also concerned about :/

The Majority of MPi tanks have a shorter filler neck. Thta is likely to be the most concusive evidence. I'm not sure sound deadening is that conclusive as I have an SPi tank with sound deadening *tongue*

Tank is immaterial. Take the pump out, read the part number of it and do a search. *wink*

My car has an SPi Tank with an MPi pump as the MPi tank weighs the same as a small plannet.
