Looking at putting together a budget EFI fuel system based around the Ford F150 pump. Going to be running a GM TBI unit.

Which Pre/Post filters should I use?

Which regulator? The 2000 vette filter/regulator combo seems cool but the pressure is way to high for me - any one make a similar one for say 20lbs?

What about fuel line - should I plumb hard lines all the way? stainless flex hoses - cloth braided hose or just cheapy rubber hose?

Anyone do this on the cheap?
Car is 69 B Body

What kind of engine are you putting this on? The gm tbi is awful low performance.

just a stockish 318 - higher fuel pressure and a custom ecu should work ok she is just a cruiser...

looking for better drivability.

Instead of using an F150 pump, why not use the GM TBI one? and with tons of pickups and suburbans in wrecking yards that had the TBI 350 in them, you could even grab the fuel lines off one..just shorten them to suit and go from there ?

(You'd get the right fittings to screw right into the throttle body that way, plus the return line, the inline fuel filter, flex sections, etc)

Well I already have a new F150 pump around from parts hoarding..and they are good for Multiport systems if I ever upgrade..

I have the lines at the throttle body - looking to build the system from the tank forward to the body.

Never thought of used lines - but the cost of bulk hard line is quite low - it would not be worth the effort to pull the lines..

Some food for thought... I swapped a magnum 318 into my carbed 88 jeep. Used a 99 dakota engine and disected the harness out of a 95 grand Cherokee. Cheaper and definitely easier than what you're planning, no tuning to do and more power than a LA 318.

Port injection as a rule runs a lot more pressure than TBI. Not compatible AFAIK.

Cheapest option would be to take the FI intake, injectors, fuel rails, regulator, wiring harness and PCM out of the same vehicle.

agree. i'd guess both the ferd pump and vette regulator are MPI. all tbi stuff is lower pressure, therefore stay with "all" tbi components. you can buy an inline pump, sorry i never remember who makes 'em. they look like the holley beer can pumps like the old commander and pro-jection used

you been to "binder planet" lots of info there on adapting and reprogramming gm computers

The GM TBI throttle body has a built in pressure regulator. You can not get much cheaper than using the GM TBI for fuel injection. The common ECUs are fully hacked and the info on them is free. You will need VSS vehicle speed sensor if you ever want consistent idle speed. All the parts can be junkyard sourced for really low prices.

why don't you just go w/ a 5.2 magnum and M1 intake? Everything is already there and you won't have to cobble something together. Really the costs of kits have dropped so much I have no idea why somebody would want to monkey w/ pieces from this and that these days.

There is no difference in fuel pumps. The regulator controls pressure by returning the excess to the tank. Just because the pump is capable of 43psi doesn't mean it has to run at that pressure. Look up a pump for a 88 Dodge 318 TBI and a 92 Magnum. Same pump. The GM TBI has the regulator built into the back of the unit. Only the 454 one was adjustable with an allen wrench, which is the same unit Holley used for the Projection 2 bbl. Run what you have, it will work just fine.

Maybe not so with deadhead systems.

But the GM TBI is well-known and can be made adjustable quite easily. There are tons of websites about these units.

Correct, I should clarify that only applies on a return type system.

What you are doing is essentially the setup on my W350. If I was going to do it again, I would use the Microsquirt. $369 with a wiring harness also. A few junkyard parts and connectors and you are up and running.

Not according to the info at RockAuto they aren't.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

I don't know how much truth there is to it, but I have been told that running a high pressure port efi pump at low pressure tbi pressure levels can drastically shorten it's lifespan.

Well with my $100 TBI system off a junk 350, my $10 ford fuel pump, my $50 hacking of the computer so I can run either Speeduino or a megasquirt equivalent ie clone...I don't the prices of kits will ever fall far enough. Add another $50 bucks for a cheap android tablet and even have remote tuning and dashboard...

And for the prices of these Ford pumps I can run 2 in paralell and keep a spare in the trunk for less than a case of decent Canadian beer..

My money is tight - and this stuff fell into my lap - plus I can make it work....where is the fun in plug and play?

good luck with that. you are already about half way there to a complete kit. AND you won't have any headaches. Hope you've done this before.

Half way? I have all Senors,wiring harness, throttle body, ecu-modded, fuel pump, return style sender unit,

I think I am a couple filters and fuel lines away...what am I missing?

I have not done this before but lots of the internet has....headaches I expect...who doesn't get those from modding classic cars...

He may be referring to being half way there financially.

Sometimes, people with slush funds forget what it's like to pinch pennies in order to reach a goal.

To some on this board, a $500 expense is insignificant. To others it represents 6 months (or more) of savings.

It's real easy to spend someone else's money.
