Fuel rail spacer

Hi all,

When I put my engine back together again a year ago I couldnít find the fuel rail spacers so I just used some washers to make one. Of course I wasnít exactly sure how tall the original ones were so I guessed. Iím thinking that I might have an injector leak issue tho and this might be part of the issue. Does anyone have one lying around they can measure for me by any chance?? I canít get ahold of one right now (special order everywhere) and I really want to try to solve this leak this weekend.

The Mitsubishi part number is MD095402.

Thanks!

S.

You definitely want to get the proper spacers for this. You won't get the proper spacing and pressure with washers alone.

This is not a good place to cheap out. A boost leak around the injector seals or any fuel-related leaks could easily lead to engine failure or worse. Spend the $20 on spacers now to save yourself from more expensive failures later.

I also recommend performing a boost leak test after seating the fuel rail. I had boost leaks around the injector seals every other year until I machined the Mitsubishi spacers down by about 0.5mm to put more pressure on the injectors. Those injector seals tend to dry out and shrink over time.

i agree - itís just an availability (not financial) issue for me - dealer is saying a week to get them, at least. They are only $8 each - just wish I could get some right now!!

thanks!

Yeah, I saw it on their site too, and have tried both calling and emailing them - no response yet. I will keep trying. I wanted to get it overnighted (Saturday delivery), but because I couldn't get ahold of them, it's too late now.

Thanks for checking for me tho!
