Just been down to the scrap yard to get a new fuel pump. I've got a Punto 85's fuel pump.

Pipes and connections are the same, but the design of the pump is more different than i thought it would be.

whats the easiest way to mod it so that it'd all fit. should i make a plate up that fits the cinquecento tank and then fit the punto pump into that? I'm a lil iffy around fuel systems, can cause big problems if it goes wrong!

whats the benifit of the new pump?i thought the cento pump would have been up to the job?

not for an MPI system, we're talking 1bar vs 3.5bar fuel pressure.

3.5bar fuel pressure you need that much? i know when my grale was mapped from 210-250bhp the fuel pressure was raised from 2.5 to 3.2bar as the grale pump is adjustable, but this was all done with a gas analyser, just seems really high. i thought it was 2.5bar on MPi's.

Silly q, but which ones which?

cento left, punto right

you see the little pump bits inside? just swop um

this bit?

was tempted to try and get the whole thing swapped over as the punto pump seems to have a better gauge sender unit. oh well though!

The cento gauge sender unit is shockingly awful isn't it, I hardly bother looking at it until the light comes on nowadays, which is every week .

its more the flickery light when cornering, love the way u can have over half a tank and get the light on

Easily, especially round our local roads

yeah that bit will be the bit wont it. tis how i thought it was done when i was looking the other day. some one wanted a 75 pump off me to do it with but they turned out to be time a waster

cento left, punto right. hmmm!

i dunno i love the idea of an empty tank when cornering hard to the right then goes full

nar you gotta swop the white bits i reckon

yeah, jsut trying to get the rubber bit off the cento one now. its a bit stuck though
