View Full Version : Fuel Pump on a Type 1?

I run a 2275 in my baja. I was down for the 1000 prerunning and it seemed like the pump or something couldnt keep up with the fuel flow in high rpm 3rd and 4th gear. I was told it could be the fuel pump not keeping up. We ran the "facet" fuel pumps, I think Purolator brand. And we run two in-line. What do you guys run on your type 1's? Thanks.

Throw away the Facet pumps and get a Holley blue or red pump.They work awsome and they are rebuildable. Just be sure to get a regulator to bring it down to 3psi for your Webers.
here are the spec's for them.
Holley blue pump , 14psi / 110gph
Holley red pump , 7psi / 97 gph

The Holley Red works good. I have also had good luck with an electric from Kragen. It is a high volume pump made by Master. I run that on a 2.9 litre Type 4 and have never run out of fuel on top end. Like Stu said regulated to 2-3 psi and you will be good to go. The Master pump runs about $35 instead of $120 for the Holley

I have had no problems with the FACET on my Class 12 race car, and ran the last Baja 1000. I used the stock mechanical and the FACET as a backup. The FACET can be used this way as it allows fuel to flow through.
Wally at ORW says he does not remember any being brought back as defective.
My 02 worth.

I've never seen a problem with a Facet that wasn't operator error. They should pre-filtered and gravity fed to the inlet, cause they push fuel. They don't have any parts to go bad, thats why they were used in aircraft.

Use the Facet. Facet make s different psi pumps also. Aircraft spruce carrys all of them. The 5-6 psi pump comes with -6 fittings isted of the 1/8th pipe. I use this one on a 4.3 vortec with a 650 and do not have any problems.

the best type is a rotory pump bosh makes one i belive but pumps are like any other eltc part its a crap shoot i run holy with a fauset sucker pump and a faucet back up primary pump knock on wood no probs but had a holy regulator play mind games with me at parker last year .

Well we ran the car on the freeway yesterday. At about 4300rpm around 65-70mph 4th gear for 20 mins straight it was fine. But as we were heading home it started to lean out again so we're not sure what we are going to do right now.

Check the floats????

Are you running a fuel cell. I've seen the foam start to come apsrt and clog the pick up before, also if you are running a fuel cell and the pick up is from the top you can have a problem sucking up the fuel. I have seen this on many of my friends trucks and have installed a in tank pump from a Volvo or VW for them and it works great. just my 2 cents.

Thanks for the help guys. Yes, we took the cell apart to clean the foam particles out so that is becoming less of a factor, if any. But the pickup is on the top of the cell so it might have trouble sucking fuel through.

The pickup hole is on the top of the cell but there is a hose inside that goes to the bottom of the cell and that is where you actual pickup is. So foam could still be picked up and clogging the filter.

i dont think the faucet pump has the voulme to pull from the top .i bet thats your problem .

I agree with 5racer. Facet recommends that the pump be gravity fed and the base should be mounted on a vertical surface with the pump at a 45 degree angle and the inlet at the bottom. I know it sounds wierd, but they are bullet proof when done that way.
If you guys found bits of fuel cell anywhere then you should pull the fittings off of the pump and look inside. I have seen incredible amounts of garbage get packed in those little pumps. They aren't capable of passing anything big.
Next week, I am going to try one as a transfer pump. I guess I'll find out if it is possible for one to suck gas out of a fuel cell. It's mounted at a 45 and below the cell. What I expect is that it won't suck unless it's primed.
Sounds like your problem occurs after running a long time. Check the routing of your fuel lines. If your fuel is getting heated it would create "lean" symptoms. You can't get as much hot fuel in the cylinder as you can cold fuel.

The facet pump can be mounted 12" from the bottom fo a tank.
I built a 10 car w/ a pick up off the top af the tank 6 years ago and it is still the same way w/o any problems.
These pumps are idiot proof.

Also check the pickup hose in the tank. The hose will get warm, then softens a little and can kink restricting fuel.

if those faucet pumps dont suck too well then how do you explain alot of people using them as sucker pumps on the carbs that have return lines?? They are loud when empty but they still suck... lol

dont need much of a pump for a sucker system they work great with 1/4 line for return

I have a Purolator red facet "vibrator" pump for my 1835cc mounted just under the rear window of my bug. It has about 10" of line from the top of the cell to the petcock shut off, then another 2" to a plastic bulb filter then another 6" to the pump, from ther it has about 3' of line to the 40mm weber carb. I have a fuel safe 22 gallon square cell mounted in the package tray area.
This stuff about pulling fuel is BS. Ive never had a problem but do carry a new spare for whatever reason.
It takes my pump less than 5 seconds to prime after turning it on. Once I have about 1/2" of fuel in the filter bulb I know its primed and start the motor. Once primed it will never run out till the tank is empty. I change the filter yearly.

I run the cheapies in line with the stocker on my 5/1600 but before I took off to the 1000 I rigged a temporary fuel press guage. I have past exp. in blown alcohol,gas boats for race and rec. Running fuel press. is so important to check also fuel line size and filter size? A filter can actually be a restricter as well. I would try the fram HPG1 canister type, ypu can unscrew it and dump out some of the silt bed we all love! Good luck! In all of this rig yourself a temporary fuel press guage you can see while at full throttle, should have at least 2lbs tapped in closest to carbs.

A Facet pump is certainly capable of pulling fuel. That doesn't change the fact that it is designed as a pusher pump.
If its mounted close enough to the tank, it doesn't have to pull very far before it gets to push.
Has anybody has anybody had success mounting one a long way from the tank? Not that I have ever seen. Fuel injection is a good example. Most use a puller to get fuel out of the tank to a pusher that pressurizes the fuel rail.

So we are trying the holley, and mckenzies told us to try the blue and so far its working. Any suggestions on the pressure I should run. Thanks.

3 to 4 lbs. is usually good. Start at 3 and run it hard. Bump it up to 4 and run it hard again. If you notice a big power or performance difference then stick with 4, otherwise go back to 3.

I don't want to JINX myself..... but here it goes.
My facet pump is mounted above the top of my fuel cell. The fuel cell is tapped from the bottom for pick-up. There is about 20"-24" of line before I have a filter. The fuel line continues another 24"-30" up to the fuel pump. From there, another filter then the carb. I have NEVER had any fuel problems (other than an empty tank) and the pump has never had a problem "sucking" fuel to prime itself.
I do carry a spare on the car, but that is just so I'll never need it.
