Thanks to SER_GTR for his guidance. swap is under his virtual supervision
The swap was neat. I dont like the way mechanic made the bracket for mount but in the end, I was the one with 103KG who was standing and jumping on the engine and I didnt hear any cracking noise.
I am having a problem. The problem is, I am using an in tank fuel pump bought new from shop. The fuel line I am using is existing old charade line which is I believe is narrow.
The car is missing on idle and when after sometime, it gets a bit steady but as soon as i push the throttle all the way, it starts woobling as there is no fuel to feed.
KEEP IN MIND THIS IS A RETURNLESS FUEL SYSTEM and my system is purely returnless I mean I even dont have regulator in tank lol, pump directly feeding injector rails.
I tried to WOT and when the engine starts woobling I put a spray of petrol and it goes like normal. Everytime I did this, seems problem resolve.
So I conclude with my limited knowledge that either it is a low or high pressure problem.
what should I change? fuel line, pump, or what? I see there is a regulator on injector rail as well. should I play with it?
