The mechanic completed the GTi swap several months back. However after a couple of months it died. A quick diagnosis at a local shop indicated that it was the fuel pump that had 'expired'. So assuming that a 1.3L would have different fuel flow requirements than a 1.0L I ordered the 1.3L and proceeded to change it out. Unfortunately when it was all out... in the middle of a Canadian winter... in the street:)... it became immediately apparent that the fuel pumps were not even close to being interchangable.

What I ordered was Carter In Tank Pump & Strainer Set; Turbin Style Connecting End for a 1990 1.3L DOHC L4 (see pic off the RockAuto site where I picked it up)

Image

However, when I popped the fuel pump access panel off the one inside was almost twice the size...

Image

If I'm reading it right it appears to be a Carter Electric In Tank; Spade Type (again, off the RockAuto site)

Image

So for those in the know, is the pump that is currently installed the correct pump for a 1.3L DOHC?

If not, would it work anyway or would it eventually kill a fuel pump designed for the 1.0L 3banger?

Can the 1.3L fuel pump be made to work with the existing wiring that is likely for a 1.0L 3cyl?

Lastly... what can I do from here to make the fuel pump work? Will it require a entire new pump mount? Maybe a whole new tank?

Thanks for the help lads!

the gt pump is bigger. the dohc engine doesn't run for shit on the smaller fuel pump.

here's a pic to show the difference.

there's also a difference in the fuel tank doors. the one for the gt has a pump mounting bracket that's bigger to accomodate the proper pump.

look at 1991 it list 2 pumps 1 of them is a 2" pump i think that is the one you need.There are some after market pumps that give you a rubber sleeve to take up the difference in diameter. check the cater web site and ck the fuel pressure for the pump you have and see if it meets specs for your car if so use the sleeve and install if possible.good luck.

When all else fails... read the instructions:)...

As quoted from the pack I didn't open as it seemed like the wrong part... put me off a bit as it definately was listed on the RockAuto site as being for the DOHC.

"This upgraded turbine style pump is a replacement for the original equipment 2" diameter pump. This smaller, more efficient design draws less current and will fit into the existing vehicle applications with the hardware provided in this kit"

I'll take a run at it tomorrow and see how it goes together. Thanks to T for the pic and HRR for the perspective...

that appears to be a standard denso 195130 style pump. very common in the japanese cars.



might be too late but there are a TON of direct bolt in pumps that will flow more than enough for whatever you will throw at that engine. 240sx, mr2 turbo, 3000gt VR4, FD rx7, mkiv supra TT....the list goes on.


those are in size from small to big. the denso supra pump is the highest flowing readily available 195130 pump out there. flows about 270 LPH but draws a LOT of current. the mr2 is about 170lph and the 3000gt is around 190LPH. stock 3000gt pumps can be had for about 50 bucks. i have around a dozen lying around.

Good info! So for comparison sake, a stock GT fuel pump should have a flow of what?
