MEP 803A fuel pump replacement

[Jerry Patenaude]

Hello
I replaced the main fuel pump with a NAPA pump rotary type .
Works good it was hard to get it started and running seem ok now
But having a problem with the 7.5 amp circuit breaker it will pop out trying to
Start. Anyone have a good idea on that can I replace it with a bigger breaker.

You don't want to go bigger because 7.5amps is there for a reason. May want to try and replace the breaker with a newer one. I've had a couple of units with weak breakers, that would pop for never reason.

Thanks I will try a new one . I was just thinking that the new pump pulled more amps than the one as I had no problems before. I hard a problem with the fuel tank had a wax build up about 1/2 inch in the bottom plugged all my lines filters . Wanted the OEM pump but could find a 24 volt all kinds of 12 volts that looked right . I fit the Carter rotary pump in place the old one was in . Fuel sender next job to do on it .
Thanks Jerry Patenaude

In the future, since the primary E1074 pump from Airtex has gone away again it seems, I believe you could have used the E8131 (https://www.summitracing.com/parts/atx-e8131). The body is the same size, you would just need to adapt the mounting slightly, and cobble some of the angle fittings off the stock pump to use with this.

Thank you
I should have checked here frist. I did checking on the fuel tank build up from the fuel glad I looked in the forums I thought I was the only one. If I had looked me it may have had the part number of the pump as they did say that the pump was replaced in most threads .
Your site is great help.
THANKS everyone for your help.
Thanks Jerry Patenaude

Some pump info here: https://www.steelsoldiers.com/threads/mep-8xx-series-fuel-pump.151124/page-2#post-2245958

This should get you close to your price point....but will need a few fittings and connectors: https://www.rockauto.com/en/partsearch/?mfr=AIRTEX&parttype=6256&partnum=E8135

Save a few pennies going with the 8131 via Rock Auto... their site is a bit screwed up though as they show like $900 in freight on this pump for me...

8131 is shown for diesel applications, where the 8135 says gas. Im sure EITHER would work in a pinch, but I would personally go with the 8131

8135 is good for gas and diesel: https://airtexasc.com/media/1178/16-universal-fuel-pump-applications.pdf
