The MPI tanks have some bitument sound deadening on the outside and are baffled inside so weight quite a bit more than the SPI items.
If something is worth doing, it's worth doing half of. |

I must have an SPi one then because its just metal all round - 1 bar should be enough for a metro turbo engine though right? On 10th Mar, 2012 theoneeyedlizard said:

OK on low boost. 1 bar is about 14psi. You need to run your fuel pressure at 3.5psi + boost, so for 8psi of boost you need 11.5psi of fuel pressure.

you can stick the MPI pump in or one from a fiesta or similar, esentially any intank inlection pump can be made to fit pretty easily. On 28th Aug, 2011 Kean said:

The MPi tank has a shorter filler neck. The filler cap sits much closer to the body. On 26th Oct, 2004 TurboDave16v said:

I'm using a ford pump fuel pUmp in mine, it's an easy swap. Just take the top cover off the tank, lift out the old pump, unclip it (easier said than done, buts it's not complicated) and refit the pump pump in it's place. I removed the pump but left the original pipe work in as I though it better.

I get a bit worried about internal fuel pumps and also buying second hand. As I am rebuilding my car from the wheels up, I would prefer to buy new.

If it was designed to go inside a tank, then putting a new one inside the tank seems sense to me On 11th Feb, 2015 robert said:

Is that an uprated flow pump Gavin? On 26th Oct, 2004 TurboDave16v said:

Would you buy a new civic/ford internal fuel pump (like this http://cgi.ebay.co.uk/WALBRO-255-FUEL-PUMP...item56353c635e) or would you remove the pump from the SPI tank and fit an external pump (like this http://www.minispares.com/Product.aspx?ty=...d=35668&title=). I'm using the Walbro 255, but I know the standard SPi injection manifold regulator never liked it. I think its to do with the set pressure since the Walbro 255 is roughly 255 liters per hour at 3 bar, but at 1 bar, the flow will be greater, so the regulator really needs to be able to flow such volume, and the return really needs to be un restrictive.
