dk_supra Posted July 28, 2008 Share Posted July 28, 2008 There is something really wrong in the whole install. You guys have removed the one way check valve that the 044 has. That's not clever, coz the pump will die in the long run from the pressure. I have 2 of this in my car, one intank and one outside. You NEED the one way check valve to protect the pumps on high boost from the constant high fuel pressure. Cheers Dimitri Quote Link to comment Share on other sites More sharing options...
Alex Posted July 28, 2008 Share Posted July 28, 2008 I can't see a difference from the first pic to the last...where is this checkvalve supposed to be? Is it on the hanger or the pump? Quote Link to comment Share on other sites More sharing options...
dk_supra Posted July 28, 2008 Share Posted July 28, 2008 It's supposed to be on the pump and then run a Banjo from the 044 to feed the fuel line. Quote Link to comment Share on other sites More sharing options...
MarkR Posted July 28, 2008 Share Posted July 28, 2008 Hi Dimitri...Have you got any pics of this? I'm trying to remember what was in the box, and I don't recall seeing a check valve... Quote Link to comment Share on other sites More sharing options...
dk_supra Posted July 28, 2008 Share Posted July 28, 2008 I'll find something in the old files, i should find something for you. Otherwise I'll get pictures tonight in the shop, from a new 044. Cheers Quote Link to comment Share on other sites More sharing options...

dk_supra Posted July 28, 2008 Share Posted July 28, 2008 And you can only fit a banjo fitting on it. Quote Link to comment Share on other sites More sharing options...
MarkR Posted July 28, 2008 Share Posted July 28, 2008 Cool, thanks. Will the banjo fitting you found on ebay fit onto the supra? Quote Link to comment Share on other sites More sharing options...
dk_supra Posted July 28, 2008 Share Posted July 28, 2008 it did fine with me. Although i did it a little bit different on my car. I bought aeroquip banjo, with 6 an, then went to a 6an 130 degrees fitting then to 6an braided and then went through the top with a 6an fitting. But keep it simple with the banjo of ebay and it will work just fine. Quote Link to comment Share on other sites More sharing options...
Wez Posted July 28, 2008 Share Posted July 28, 2008 I am confused, looking in the pics that Si has posted the check valve is in place without a banjo fitting, why can you only use a banjo? Quote Link to comment Share on other sites More sharing options...
dk_supra Posted July 28, 2008 Share Posted July 28, 2008 because it´s that kind of a check valve, that you can only use a banjo. Quote Link to comment Share on other sites More sharing options...
bolarbag Posted July 28, 2008 Share Posted July 28, 2008 As an alternative can't you just replace the check valve supplied with an NPT/AN type fitting? How noisy is not very noisy at all? Are you full interior Heckler? Quote Link to comment Share on other sites More sharing options...
dk_supra Posted July 28, 2008 Share Posted July 28, 2008 If you replace the check valve then the fuel pressure is forcing 100% of the time the pump bearings and internals. This way you are putting extra wear and tear on the pump for no reason. Result i have seen a 044 fail in about 7,500km due to this mistake running at 4,5-5 bars on full boost, that's like 3bars on 0 pressure. So it is wiser to keep the check valve, or just buy an inline one from aeromotive or some other company. BUT YOU need a check valve. This is how an EFI system should work. Think about all the pulses of the injectors, hitting the pump, if there is a check valve, no fuel vibration will even come close to the pump.

Are you full interior Heckler? I have full interior. when i ran the pump that was with me looking in the boot with everything removed, I didnt think i was too loud.
