Hey guys, been doing lots of reading/research on a fuel pump. Looks like the walbro gss340 fuel pump is a good choice, I am just looking for a 255lph to support around 500hp na. Plan to get the hot wire kit from racetronix as well.

After doing lots of digging the last few days I have found that some folks will grind a bit off the bottom of the bucket and put the fuel sock on the bottom outside of the butcket AND some will just grind the top opening of the bucket and kind of bend the fuel sock around the pump, then stuff the whole pump/sock assembly into the bucket.

Does anyone have any input or opinions on this and which route to go?

 

If I was going to replace my pump I would go with one of these.

Providing its a NA system.

 

Awesome! Thank you sir. Do you think the hot wire kit is necessary on those as well?

 

Those units were designed as a drop in with existing wiring. If a guy wanted to upgrade the power and ground wire to a heavier gauge it certainly wouldn't hurt. The pump that is in those drop-ins is actually the "Walbro 450."

There was a write up in the forced induction section from one of the members that used one on a turbo 2500hd build.

I just found that thread through a google search and was just reading through it. Thank you Drew.

I had thought the walbro 450 would overpower the stock regulator on the returnless system?

 

Not a problem with those drop in units. They are GTG.

 

Thank you for all the help and information.

 

Too bad those don't fit the 07.5+ trucks or I would order one today

 

There are some offerings for the 07.5+ that may work for you. They are offered by another seller. what is your year/make/engine

 

A walbro 450 is not a 255lph pump. They advertise as a 255lph unit.
