| Post subject: | Whats your fuel pump? |
I'm just curious to know which type of fuel pumps everybody is using. My fuel pump is next in line for a rebuild. Please mention your basic engine specs. |

I got a 3psi Facet fuel pump, does the job on my engine, which is a pretty stock S motor. I bought myself supercharger which will go in when I can afford to pay for the kit, and still I reckon the 3 psi pump wil lbe fine, if not I'll try a 6psi facet pump that I used to use on my car, don't think it effected the carbies but I have read that SU's don't like more than 2-4 psi. Cooper S stock was rated with a 3psi SU fuel pump. |

Same as above, no regulator. Single HIF6 on 1275 motor with dyno results posted somewhere... EDIT: I forgot I modified the Facet. Standard return spring in the guts was too strong and the pump wouldn't self prime above the fuel level. I found a spring of suitable diameter and pit it in and now she pulses slower but will self prime. M |

There is a big difference between pressure and volume. With carbies you don't need much pressure but you may need a larger volume. |

I have the same as slinkey. 3psi solid state facet. I run a 1310 A+, 12g940 unleaded head ported polished, kent 286 cam, omega dished pistons, 45dcoe weber on medium manifold. Its a pretty thirsty motor but the facet copes more that adequatly, I have a purolator fuel regulator just near the carby to keep things nice and smooth. |

3psi Facet/Purolator/TRW, (all same really) both cars. 1293 and 1360. Mount it on a Mini square exhaust mount, it really shuts it up. 
Mokesta, these pumps are really meant to be mounted below fuel level, this will ensure freedom from vapour lock in hot weather too. Worst place to put a pump is up on the firewall, where Morris Minors had it.

Agreed Doc but on a moke it's no easy task to run a line from the tank compartment to the rear subby and then forward again. My alloy tank has a pump mount inside which currently holds an EFI pump. The Facet was just there until I finished the EFI manifold and swapped over. Unfortunately the EFI computer $ stopped that project for a while so I've got a less than optimal pump location. Next time I'm bored, out comes the tank and in goes an in-tank low pressure pump. The facet paperwork says it is capable of priming up to 12 inches of inlet head difference, but it actually couldn't. |

People do seem to spend a lot of time worrying about fuel volume - if you take the crappiest old 'lectric fuel pump there is (mine for example!) and pump into a jar instead of your carb, you'll see one hell of a lot of fuel in just a few seconds. If your engine is using that much A) you'll have a range of about 4 miles and B) it's poked So yes, worry about correct pressure, not volume. |

VL commodore 044 on EFI. Want to make a surge tank and put an in-tank walbro type, currently using diesel fuel filter (about 600cc) as surge tank! Daniel |

On Skippy (now W33VAN) I used a Mazda 929 fuel pump that looked like a Facet. Cost me $2 at a garage sale. On the Auto-Moke I have a 6psi Facet. Too much pressure. I need to change pump or fit a regulator. Or I could fit a return line, as the HIF38 I have not fitted yet has the return line outlet. But taking out the Moke tank and brazing in a return line fitting doesn't bear thinking about! Cheers, |

On a 1310 motor with a modded 12G940 head and MG Metro cam, with a HIF44, I have the standard diaphragm fuel pump. Doesn't seem to be a problem as the motor currently pulls 7,000 rpm in all four gears. I have the luxury of country roads where I can rev it out on occasions. |
