Inline fuel pumps I have been reading threads about fuel systems and have some ideas. I'm swapping an LS1 into a Nissan 240sx and plan on running an inline fuel pump to a corvette filter/regulator. I was wondering which pumps were recommended in this situation? I plan on running 3/8 steel line, this LS1 is stock right now, but I might upgrade the engine later on. I saw the Walbro stuff but i don't like that metric thread most of their pumps seem to have. Any have plain SAE fittings?
The Aeromotive A1000 pump is rated for continous duty. There are a LOT of different pumps that will supply plenty of fuel, but the majority of them aren't made for the continous duty of street driving.
You have a metric automobile with a metric engine, but you don't want metric threads on the fuel pump?
The walbro or bosch pump is the way to go for your set up The A1000 is suppose to be a nice pump, but I don't know. It has way more capacity than you will need and is more than 3 times as much.

My LS1 test stand fuel system with the Walbro 255lph pump and Corvette regulator/filter. I also have a paper pre-filter which is designed for a carb but is perfect for this use. Fuel pressure with engine off - 5min as it slowly drops off. the last picture are the fittings you can buy from this web site for the Walbro pump - pretty cool. I also purchased Swagelok compression fittings and they work absolutely perfectly. The fuel line you see is rated for FI on the pressure side of the pump. The feed and return is not as the pressure requirements are low. I bought my pump from Jegs for $99 which seemed to have the best prices. As a side note the pump is very quiet for an external pump but after I hit the ignition I don't hear that anymore!

the bosch pumps are nice but they are double the money of a walbro and only $100 less than an aeromotive. If you are going to spend that much then just get an aeromotive EFI pump. Looks alot like an A1000 but is rated for less GPM and is less money. JMHO

I second the bosch 044, aeromotives are overkill for a stock motor (or a mildly built one)and are a lot louder. Haven't played with walbro, i know a lot of people do though, the bosch is an OEM pump so quality is supposedly very good and will support up to 700hp i beleive. There are a fair amount of people with problems with their a1000s. Do some searching before you go that route. A company called Jay racing has the 044 pump and adapters to get you to AN line sizes, fittings are always going to be a headache, going from hardline to braided and one size to another, so i wouldn't let that aspect sway you away or towards any pump in particular, it's best to make a drawing of your system and map out sizes so you can order the correct adapters/fittings, ect.
good luck
as a side note: aeromotive recommends using one of their fuel pump regulators if you use a a1000 on the street, otherwise the pump heats the fuel too much and can cause vapor lock and premature pump failure, the controller is big money too, just for consideration
