What PSI electric pump do I need for a 2.8 2bbl?

3-6, 3-7, 5-9, 5-10

I would think the 3-7 would be best?

Thanks

need to mesage ked85, he is doing a electric fuel pump swap. I belive he is using an old one from an opal automobile.

 

3-6 PSI is MORE than enough, realistically, your car only needs like 4. SO it's certainly more than enough.

I HIGHLY recommend going with the Purolator electronic fuel pump.

They are SOOO inexpensive, but the quality is excellent on them. I am currently using them on two of my cars.

1981 Pontiac TransAm with a 350 V8, and a 4-bbl Edelbrock 600cfm carburetor,

1973 Volkswagen Transporter with the 1800cc motor and 2-bbl Webber carburetor.

They are really great fuel pumps. Small, easy to install, I highly recommend them. I usually wire them directly to the ignition POWER wire.

I keep a spare one in the Volkswagen, but it's never gone out on me.

 

Where do I pick one of thesde bad boys up? All the local shops have their own brand of universal electric pumps.

Thanks!

 

The model numbers are:

Purolator:

pro12s_3x
pro42s_3x


Summit Racing sells them I believe.

 

I dont know what the intended pourpose of this truck will be but if you plan on driving out of town at all I wouldent reccomend the cheap purolator buzz box. It's a good pump for somthing in town but Ive had a few fail on me so I couldent reccomend one. You best bet is to break down and buy a rotary style pump, yes purolator makes them also, bosh, Master, Delco and juyst about everybody. thier kinda of pricey avrage about $60 but it's an extremly quite pump and hasent given me or and of the cars trucks or RV's Ive put them on any problems WSE. You should use a regulator with any inline pump Purolator makes a $24 that is good and most can be found in the chrome section of any parts store along with the pump.

 

For my 3.4 swap into my Blazer, I purchased a Carter Electric Fuel Pump.
Why a $65 Carter Fuel Pump when Kragen sells the less expensive items (Purolator item & the like ones)?
Longevity & reliability & not desiring to break down.
I do have an external electric fuel pump from my old 1975 Bosch Fuel Injected Opel Sport Wagon.
I did not use it on my Blazer 3.4 swap.
The Carter pump is regulated 5-7 pressure & the Opel Bosch Electric extrenal mount Fuel pump kicks out 40 pounds of pressure.
A regulator to take a 40 pound reading down to 5-7 for the Rochester 2SE carb was astronomical in price.
The Carter Fuel Pump is a bargin.
Get the best one you can & never worry.

FYI 3.4 engine blocks DO NOT HAVE A PROVISION FOR A MECHAICAL FUEL PUMP. Nor do the 2.8 MPFI blocks nor 3.1 blocks

You should be able to see the Carter pump in the engine bay of this pic.
This is a temporary set up, until I get engine in truck sorted out with minor details.
Then I'll place pump on frame rails by the tank

 

Aghhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh A vacuum line monster!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

How does ypur Blazer Run Karl? I hope it runs better then mine did.

 

When I got this Jimmy it had all the vac lines and such disconnected because they pulled the carb looking to see where the *knocking* was coming from. Hehe bad rod I suspect. Didn't wanna take a chance and had this 6 month old Camaro motor in my fingers for it.

Can't wait to play Vacuum tag!

 

I have the hose routing map IF that is a help to you.
Give me a bit to take that picture for you & then I'll post it or send me an email & I'll forward it to you that way.


My Blazer will run fine as soon as the pushrods are adjusted better.
Then once that is done, I attach all the smog stuff & go for my smog test.
I took it for a short drive (with noisy valve train) & BOY could I feel the torque!
This Blazer was to be my vehicle for using while I fix a house I bought (that is going up for sale very soon).

Let me tell ya, a Firebird can haul
4' x 8' sheets of wood
5' x 3' sheets of cement
MULTIPLE BOXES OF CERAMIC TILES (about maybe 300 - 600 pounds of the stuff!), bags of ceramic cement & family, all without braking a coil spring!
Also very handy for hauling 16 foot sections of trim!
This pic, I had carried only 5 pieces of 16 foot trim. Largest trim load with family was eleven!

Give a shout if you would like a pic of the vacuum hose set up.
Do you own a 49 state Jimmy? Or a CA version Jimmy?
