I have highlighted before that I have bought a standard Metro Turbo fuel pump, and the inlet is 10mm OD and the outlet is 8mm OD. The outlet is the perfect size because it mateches my 8mm ID fuel hose to the regulator, but my problem is still with the fuel pump inlet. My fuel tank (a custom made alloy tank) has an 8mm outlet, and as some members on here suggested, a reducer would be required to plumb the two together.

Just use the reducer, i've seen it done on high pressure injection engine with the same pump, no problems. You'll also probibly find that most people on here using the same pump use a reducer in a similar manor.

We fed the pump in the metro van from the standard 6mm feed from the factory tank with a reducer. Had no problems at all. On 11th Feb, 2015 robert said:

I would try to stretch 8mm pipe onto the pump, then you wont have an adaptor causing a restriction.

as with getting anything into a hole that's too small its just a case of getting it hot and lubricated!! On 28th Aug, 2011 Kean said:

Seriously though, 8mm hose is already stretched to 10mm on the barb of the fitting, so stretching an 8mm hose onto a 10mm fitting you are actually trying to stretch it to 12mm................Just wont happen, and if it does, it'll split, and i'd rather have the fuel going through the engine that onto the floor

If you think about this. A similar pump with an inlet of 8mm is doing exactly the same thing as a pump with a 10mm inlet and a reducer. There is no efi pump with an 8mm inlet though. On 24th Mar, 2013 Joe C said:

I have a filter before the pump, its just one of those ones with gauze in to stop small children and the like. On 28th Aug, 2011 Kean said:

If you put the fuel return to the pump input it will reduce any fuel restriction to just the length of time it takes for the fuel to start returning after starting the pump. |
