Look at a Summit Racing or Jegs catalog for a part number. Just FYI, if you have a good 13mm model 100 (450cc or more), that pump won't be adequate.

Probably dumb question would you run a regulator or straight to filter housing

real world test stand results = with a 5 mm camshaft you will need min. 80 psi @ 2.5 gpm. prefer 100 psi . go belt drive. hyper has a nice setup just for that and it works !! best if you have a dual feed hsg. and a good pump builder will use a head with extra charge port holes for better port filling.with a single plunger doing all the work, there is very little time to charge the plunger inlet port,,there is a sprayer pump. 12 volt that will supply the flow and pressure, but it will have a short life in this application

12-802 is the blue. I prefer the black 12-815, but I carry the BigEnd generic version which is much less $, and still made by holley, and has metal blades unlike the procomp knock-offs.

that pump will not have near enough flow to supply 13 mm..head seizure is very probable

Aeromotive A1000. May not seem cheap right away, but it'll have the flow, so its cheaper than seizing a head in a 13mm rotary...........

The blue Holley electric pump we called it a 110 Holley 110 gallons an hour I think it was more for a gas motor than diesel I ran an external regulator.It would feed two 1150 Dominator 4 barrel carbs truck pulling 614 Ford in the early 1980's. The red 110 Holley had a built in regulator flowed a little less 108 gph worked good with one 4 barrel on my old super stock Dodge 482 cid never ran out of fuel.

Yes you need to be running 80lbs pressure down the track, put a belt drive pump on and be done with it. 13mm pump takes pressure to work.

The holley pump is for gas only and it's maximum pressure is 14 psi no where near what you need a great pump to feed carbs on race gas none the less.
