i have an 05 evo 8 and when it is hot the car doesnt start the first time due to the fuel pump relays overheating but once it does start the fuel pump is whining. is that because of the overheated relays or what?

any ideas? kinda new to evos

thanksss

 

Common whine from the rear, mine is noticeable too. Walboro 255?

 

infamous walbro whine

 

oh maybe it is i never actually looked, i just picked it up a few weeks ago it looked all stock but u could hear the cams and i guess it has a walbro haha.

i just gotta rewire the relays so they dont over heat now fml

 

First you need to figure out why the fuel pump relays are overheating or replace the relay. If you have an aftermarket fuel pump, majority of them all have a high pitch whine. If this recently started whining, you need to replace the fuel pump before you breakdown.

 

no it didnt recently start whining but ive only had the car about 3 weeks. the whole time ive had it it has done it ill look to see what it has when i get over my flu. and i need to look into the relays

 

common with the 255lph walbros. Mine does it on hot humid days or after an hour drive or so which I rarely execute.

 

same here. Walbro 255 whines too loud.
Any other replacement for walbro out yet?

 

Nothing with the drop in capability that can support that type of flow is readily available. You can get different weld in units or other in line options, but the 255lph they make is the most sensible option that is a direct stock replacement.

Sounds like the normal whine to me. I had one that was pretty loud at one point. Never went out on me though, I switched it before its death I suppose.

 

i c

 

same thing. mine sounds like a printer

 

As all of the other guys stated. It is just the walbro whine. IF you want, pull the fuel pump out. It is stamped if it is the walbro. I have installed atleast 15 fuel pumps. Mine of course being the loudest. Mine sounds like it isnt even in my tank...

 

Mine is really loud also. My friends say I have a fish tank in the back of my DSM.

 

how long after they start to whine do they die out? Ive only started to hear mine whine since it got hot out... Is that happening because of the heat?

thanx

 

I have the whine also.i kind of like it lol
