bosch 040 install

[hanyou]

hey peoples having problems installing the bosch 040.. ive got a r33 skyline series 2.. ive read a tutorial on the 989 or watever and yeah just few things im not sure of.

what im upto got everything off.. and hav found that the holder for the std fuel pump is way too small to fit the bosch 040.. so wat i have done is just bent the bottom bit straight and then just cable tied it to the pole.. is that alright to do?.

next thing is.. the positive and negative connectors to the actual pump.. ive stripped the wires and wrapped it around the connector and just put a bolt ontop of it.. is that ok? i have worries about it tho, cause the positive on the old pump was coverd with a black rubber however doesnt fit the new pump..

ive pretty much just replaced the std fuel pump with my new pump exactly. is that wat ur spose to do or are u meant to make modifications?. also ive found that the sock connected to the std fuel pump dont fit no where on the bosch 040.. am i spose to jus leave it off?..

what should i fix or be doing? thanks for your help guys.

most of that sounds right dude, there is nothing wrong with cable ties....they are designed to hold things and they do it well. as for the wiring....aslong as the positive is touching nothing but the postive terminal, it will be fine without the boot, the boot wouldve been there just to stop it coming in contact with anything. as for the sock....its purpose is to stop the pump sucking up any crap from the bottom of the tank....its probably a good idea to find a way to put it on or to think of something else..... even if you cut the adaptor off the sock and cable tie it directly to the inlet of the pump..

cheers

the 040s have a mesh/gauze on the base don't they (ie. filter)? there's no need to try and fit the stock filter sock. it'll mean that the reach won't be as far as the standard pump but i don't think that's anything major...

ziptieing.. i would take it out and replace those zipties with the right size hose clams

its safer and stronger

wazz....the fuel pump doesnt move around....i put a fuel pump in a mates 180, used cable ties....been over a year, hasnt moved at all....there is nothing wrong with zip ties. hose clamps can be over tightened and either damage the pump or the clamp, resulting in a useless clamp. why does everyone see zip ties as being dodgy??? why not get some aircraft grade T-Bolt hose clamps.

My opinion.....

1. Make sure the Bosch 040 is installed at the lowest point so it can be right near the bottom of the tank. Bending the cradle straight at the bottom is a good idea

2. Use electrical end terminals for the wiring part & soilder or crimp them.

3. Use nuts (stainless steel if you can) to place wire terminals on to pump

4. Use stainless steel clamps to hold the pump into place.

As for zip ties , I won't want that pump coming lose and the terminals moving about........bang.

I also wouldn't like anything contaminating my fuel, eg plastics, rust from metals.

Also the bosch 040 pump has a built in filter, no need for sock and the reason for it being mounted very low in tank.

Yeah I asked Bosch about the need for a sock on the bottom and they said it didn't need one. Stainless steel hose clamps are the go in my opinion. I bent the cradle out flat as well, then used the rubber base that the old pump was sitting on as a sort of 'cushion' to stop the 040 from making noise. Works really well, no noise at all until the car is almost out of fuel.
