MiKa Donating Members 4,243 Member For: 18y 6m 3d Gender: Male Location: Melbourne, VIC Posted 03/08/11 12:43 AM Share Posted 03/08/11 12:43 AM Ok my first walbro fuel pump was bought off ebay, genuine or not I dunno.. was installed by nizpro. Lasted a while, got fairly noisy, and was surging a lot more even with around half a tank full of fuel. After getting a few new parts and a dyno readout, it showed that the engine wasn't getting the amount of fuel asked by the tune.. Came to the conclusion 'faulty' pump..This time round, do the right thing buy from a forum sponsor, get installed by a forum sponsor.. The pump worked well and the tune was running a bit rich this time after another dyne run... Could drive with under 1/4 tank and have no surging (not giving it a boot full obviously)... Now, its got all the symptoms the first pump had, accelerating with around 1/4 tank and it surges, I went to overtake on the freeway, not hard at all just to get around a car and it surged.. Haven't put it back on the dyno yet to see what is join on, but I have a good idea...Its really annoying, I know a surge tank is the best option, but I can't afford one atm, I'm almost tempted to put a factory pump back in, they didn't surge? Surely a ford pump can handle 250rwkw's, until I get a few other things sorted with the car and save up for a surge tank, I just don't want anything bad happening till then (BANG!!)What do you think I should do..

So till then instead of going another Walbro, just chuck a stocker back in, cause even that should be good to feed the surge... Link to comment Share on other sites More sharing options...

Try that and cheap to replace make sure they don't give you a N/A regulator. Edited 03/08/11 03:22 AM by pazzo xr6t Link to comment Share on other sites More sharing options...

The car now starts straight away, runs smoother and I have about 1/4 tank of fuel left and it didn't even think of surging... Couldn't be happier, Just gotta save for a surge tank, among the other million things I want..What a pain in the ass those 3 fuel lines were to get off, the first 2 went ok, but the last one took like 20 mins of swearing and trying to use a few different tools before it came off. The pump I bought was the whole unit, so that part was a quick changeover.. Edited 10/09/11 12:34 AM by MiKa Link to comment Share on other sites More sharing options...

Like doesn't go when you put the foot in it? Link to comment Share on other sites More sharing options...

Sorta feels like when traction control kicks in.Yeah I knew how to do it, was still a bitch, as I said before the first 2 came off fairly easily, it was just the last one that gave me grief.. The ribbed bits didn't want to budge.. Edited 20/09/11 10:31 AM by MiKa Link to comment Share on other sites More sharing options...
