Aftermarket alternative for fuel pump for 90~? S/C Sambar EN07
This is a higher pressure pump than used on carb'd engine.
Jideco E8059 [NAPA uses same #] as used on following stock apps:
- Subaru DL 1986~1989
- Subaru GL 1986~1989
- Subaru GL-10 1986~1989
- Subaru Loyale 1990~1994
- Subaru Loyale Turbo 1990
- All above are TBI
The stock pump is pictured below - they can be Hitachi or Jecs or ? brands
This is the aftermarket Jideco pump
What you have to do to make this pump work on a Sambar:
- Although the mounting flange with the rubber grommets looks the same it is not quite the same. The mounting holes have slightly different centers. So I reused the old mount.
- This brings us to problem #2 - To use the new pump in the old bracket.
The new pump [Jideco] is quite a bit smaller O.D. than the oem pump, something like 41 mm vs 54 mm O.D..
I made up a sleeve to go around the new pump to bring it up to the O.D. of the oem pump so the clamp would hold it securly in place.
- Problem #3 - The plug on the wiring harness is different than on the Sambar so I soldered and heatshrinked my old connector on to the new pump.
- The good news is that both the inlet and outlet are the correct size and orientation
When I got my truck it wouldn't start due to a failed pump so I installed a used stock pump from a importer to get it going.
That pump cost me $200.00 CAD and lasted less than a year and less than 10K kms
and was getting ready to go again.
The list price on the NAPA pump is $133.00 CAD and a far better value than getting a used pump of unknown quality
Things to consider for using other than a stock fuel pump:
The volume that the stock pump puts out is matched to what the engine uses for fuel in a hour with a safety factor built in.
Excess fuel beyond what the engine uses at any given time is returned via the return line to the tank.
Choosing to large a volume pump for the EN07 will return a large volume of fuel via the return line which will start heating up the fuel quite a bit.
I looked for the smallest size engine [1800 cc and 90 HP] that was fuel injected and that had a similar configuration on the inlet/ outlet that I could find

not sure if I'm allowed to post in this thread, but after roughly 3 years of use, how's the aftermarket puel pump doing? Any issues to speak of?
